These homes were constructed as part of the Brightwalk Phase 8 Development (Phase 8 Development) in Charlotte, North Carolina (Site). The Brightwalk Phase 8 development is part of the Double Oaks Brownfields Project (Brownfields Project No. 11037-01-060). A Site location map is provided as Figure 1. The Double Oaks Brownfields property is developed with residential apartments, townhomes, and single-family homes. The Phase 8 Development includes eight (8) single family homes located along Double Oaks Road which is near the former Double Oaks Landfill. The former Double Oaks Landfill is managed in the North Carolina Department of Environmental Quality (DEQ) Pre-Regulatory Landfill Program (Project No. NONCD0000806). The Pre-Regulatory Landfill Program capped the former landfill area in 2014. Prior soil gas sampling at the Double Oaks Landfill site has indicated the presence of elevated methane concentrations. Due to the proximity of the Phase 8 Development to the former Double Oaks Landfill and the presence of elevated methane levels in soil gas, Geoscience Group, LLC (Geoscience) prepared the Methane Vapor Mitigation System Design and Methane Vapor Mitigation Operation and Maintenance Plan (MVMP) dated May 26, 2017 for the proposed single family residential homes. The purpose of the MVMP was to mitigate potential methane vapor intrusion in the homes constructed as part of the Phase 8 Development. The MVMP was provided to DEQ and subsequently approved by the Brownfields Program in a letter dated June 12, 2017. The 2 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Charlotte Mecklenburg Housing Partnership - CHP/CHP-041 Double Oaks Methane/Report/Draft _Methane VMS Double Oaks Rev 1.doc MVMSs were installed as part of the Phase 8 construction. The single-family homes with MVMSs include: 2531, 2535, 2539, 2601, 2605, 2609, 2613, and 2617 Double Oaks Road (Figure 2). The Phase 8 construction was completed in approximately December 2017. As-built drawings or a construction completion report for the MVMS installation was not available in DEQ files and Geosciences has failed to provide these documents to Hart & Hickman. However, the MVMP indicates that each home is equipped with a MVMS. According to the MVMP, the primary components of the MVMSs include a minimum 4-inch- thick gravel sub-slab base, sub-slab corrugated 4-inch diameter PVC piping, a 15-mil vapor barrier, radial blower, and PVC exhaust vent stack. MVMS monitoring equipment includes an analog manometer installed on the radial blower, two (2) sub-slab monitoring points installed in the living area of each home, and indoor methane monitors. The MVMP indicates that two (2) methane sensors are installed in each home and one (1) methane sensor is installed in each garage. The MVMP also includes requirements for “Initial Performance Testing” following installation of the MVMS. The Initial Performance Testing described in the MVMP included collection of differential pressure readings from the sub-slab sample ports installed in each home and the collection of sub-slab and indoor air samples for laboratory analysis of volatile organic compounds (VOCs) by EPA Method TO-15 and methane by EPA Method 8015M or EPA Method D1946. Geoscience provided H&H with data summary tables and laboratory analytical data summarizing the results of the differential pressure testing, sub-slab sampling, and indoor air sampling conducted in December 2017 and January 2018. The summary tables prepared by Geoscience along with laboratory analytical reports are provided in Appendix A. The sub-slab and indoor air samples submitted for laboratory analysis were collected concurrently. Please note that although differential pressure and soil gas data is available for the sub-slab monitoring points installed in each home, not all sub-slab monitoring points were identified during the inspection conducted by H&H in May 2021 (discussed further in Section 2.0). 3 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Charlotte Mecklenburg Housing Partnership - CHP/CHP-041 Double Oaks Methane/Report/Draft _Methane VMS Double Oaks Rev 1.doc As shown in Appendix A, results of the differential pressure testing conducted in the homes indicated the presence of a differential pressure below the slab ranging from -0.85 inches of water column (WIC) to -1.12 WIC. The differential pressure documented by Geosciences exceed the DEQ minimum sub-slab depressurization requirement of -0.016 WIC. This result indicates that the MVMS is effective at mitigating potential vapor intrusion. Laboratory analytical results of the methane analysis for sub-slab and indoor air samples collected from the homes that were tested did not indicate the presence of methane above laboratory detection limits. Laboratory analytical results of sub-slab TO-15 analysis indicated the presence of the VOC chloroform above the DWM Residential Vapor Intrusion Soil Gas Screening Level (SGSL) of 4.1 µg/L in samples 344SS (7.34 µg/m3), 345SS (8.78 µg/m3), and 347SS (152 µg/m3). However, chloroform was not detected in the indoor air sample collected from those locations. No other VOCs were detected in the sub-slab samples collected above DWM Residential SGSLs. Laboratory analytical results for indoor air samples collected from the homes indicated the presence of the VOCs benzene, ethylbenzene, 4-methyl-2-pentanone, methyl butyl ketone, 2- propanol, naphthalene, isopropanol, tetrachloroethylene, and/or xylenes above DWM Residential Indoor Air Screening Levels (IASLs). Trichloroethene (TCE) was not detected in the indoor air samples (or subslab vapor samples). Indoor air concentrations do not correlate with subslab vapor data. In fact, indoor air constituent concentrations are higher than sub-slab concentrations or were not detected in sub-slab samples. Because attenuation occurs between sub-slab and indoor air during structural vapor intrusion, these data suggest an alternate source for the indoor air compounds. As such, the concentrations detected in the indoor air samples are attributed to background and/or indoor sources, such as off-gassing building materials in the homes which were new at the time. Following the initial performance testing, the MVMP indicates “Routine System Inspection” activities will be conducted. Routine System Inspection activities described in the MVMP 4 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Charlotte Mecklenburg Housing Partnership - CHP/CHP-041 Double Oaks Methane/Report/Draft _Methane VMS Double Oaks Rev 1.doc generally include: inspecting system components, confirming system operation, and recording the “maximum methane concentration” detected by the methane sensors installed in each home since the previous inspection. The MVMP indicates that the Routine System Inspection should be conducted daily for the first week of operation, monthly for the first year, and semi-annually thereafter. On April 27, 2021, DreamKey was notified by DEQ that a report documenting the installation of the MVMS and results of routine inspections had not been received. Accordingly, DreamKey contacted H&H to inspect and confirm operation of the MVMS. Following H&H’s MVMS inspection, DEQ personnel visited the Site to meet with DreamKey and H&H to observe MVMS operation in select homes. A discussion of the MVMS inspection activities conducted by H&H and subsequent DEQ Site visit is provided below. 5 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Charlotte Mecklenburg Housing Partnership - CHP/CHP-041 Double Oaks Methane/Report/Draft _Methane VMS Double Oaks Rev 1.doc 2.0 MVMS Inspection and O&M On May 14 and 17, 2021, H&H conducted MVMS inspection and O&M activities at each home in the Phase 8 Development. The inspection activities were conducted in accordance with the “Routine System Inspection” procedure described in the approved MVMP. The inspection activities conducted by H&H included: identifying system components, confirming system blower operation, confirming system vents were unobstructed, confirming the presence of methane sensors in each home and garage, checking for the highest methane reading detected by the sensors since the last inspection, and recording the manufacture date for each sensor. As part of the MVMS inspection, H&H completed a “Methane and Vapor Intrusion Mitigation System Inspection Form” (Inspection Form) for each home which is the form prepared by Geosciences and provided in the approved MVMP. Copies of the Inspection Forms completed by H&H personnel are provided in Appendix B and our finding are summarized below. Results of the inspection conducted by H&H indicated that the MVMS blowers were operational for each home, and the exhaust vents were unobstructed. MVMS blower operation was confirmed by visually observing the u-tube manometer installed on each MVMS fan. Manometer readings ranged from 0.5 inches of water column (in WC) to 1.6 in WC. Please note that 3 manometers were observed by H&H during the inspection to be damaged or in poor condition. Accordingly, these manometers were replaced by H&H on May 21, 2021 and measurements were collected. H&H also noted that some of the u-tube manometers had some apparent fluid loss. The loss of fluid is likely due to evaporative loss. Over time, manometer fluid loss may prevent accurate differential pressure readings. Following confirmation of MVMS blower operation, H&H located the methane sensors installed in each home and garage. Once located, the “test” button was pushed on each sensor to confirm the sensors operated normally. The homeowners were also asked to confirm if they had experienced an explosive gas alarm during their occupancy. The owners reported to H&H that an explosive gas alarm had not occurred. 6 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Charlotte Mecklenburg Housing Partnership - CHP/CHP-041 Double Oaks Methane/Report/Draft _Methane VMS Double Oaks Rev 1.doc H&H identified that the sensors installed in the homes are Kidde® Plug-In Operated Carbon Monoxide and Explosive Gas Alarms (model no. KN-COEG-3) (Kidde sensor). The Kidde sensors are designed to produce an audible alarm if explosive gas (natural gas or propane) is detected at 25% of the lower explosive limit (LEL). The Kidde sensor does not have a maximum methane concentration memory feature. As such, maximum methane readings are not available. The user manual for the Kidde sensor is provided in Appendix C. H&H has attempted to find methane sensors designed for residential use with a maximum methane concentration memory feature but has not been able to identify such a device. During the inspection, at least one methane sensor was identified to be missing and/or malfunctioning in three homes (2601 Double Oaks, 2605 Double Oaks, and 2539 Double Oaks). Owners with missing sensors reported that they were provided sensors upon moving in, but they were recently discarded by the owners. Missing and malfunctioning sensors were subsequently replaced by H&H on May 21 and May 24, 2021. The replacement sensors are First Alert® Combination Explosive Gas and Carbon Monoxide Alarms (model no. GCO1CN) (First Alert sensor). Similar to the Kidde sensors, the First Alert sensors do not have a maximum methane reading memory feature but produce an audible alarm if explosive gas is detected above 25% of the LEL. The user manual for the First Alert sensor is provided in Appendix C. H&H also recorded the manufacture date of the methane sensors as part of the inspection activities. Manufacture dates for the sensors are included in the Inspection Forms in Appendix B. In accordance with approved MVMP and user manual, sensors should be replaced after a period of 5 years. Excluding the new sensors provided by H&H as part of the MVMS inspection activities, manufacture dates for the sensors range from December 2016 to September 2017, which are currently within the 5-year operation life for the sensors. During the O&M visit, H&H observed one potential sub-slab monitoring point behind an interior blank outlet cover plate near the front entrance of 2617 Double Oaks Rd. The location of the potential sub-slab monitoring point in 2617 Double Oaks Rd. is consistent with the location 7 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Charlotte Mecklenburg Housing Partnership - CHP/CHP-041 Double Oaks Methane/Report/Draft _Methane VMS Double Oaks Rev 1.doc depicted in the MVMS design prepared by Geosciences. Locations of other potential sub-slab monitoring points were not apparent during the O&M visit. 8 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Charlotte Mecklenburg Housing Partnership - CHP/CHP-041 Double Oaks Methane/Report/Draft _Methane VMS Double Oaks Rev 1.doc 3.0 DEQ Site Visit Following H&H’s MVMS inspection, DEQ conducted a site visit on May 21, 2021. The purpose of the DEQ Site visit was to observe the MVMS in select homes. H&H was present during the DEQ Site visit and assisted with coordination with access to the homes and identifying MVMS components. DEQ appeared to be satisfied with the methane mitigation and monitoring system. During the inspection, DEQ identified three landfill gas probes (LG-23, LG-24, and LG-25) installed on the perimeter of the closed landfill along Woodward Ave. These probes were installed as part of pre-regulatory landfill assessment activities for the former Double Oaks Landfill. During the Site visit, DEQ requested that H&H collect methane readings from those landfill gas probes. Locations of the landfill gas probes are shown on Figure 2. H&H collected methane readings from the landfill gas probes utilizing a calibrated GEM5000 methane gas detector. Please note that a connection port was not installed on the landfill gas probe plug to allow for a sealed connection to the GEM5000. However, H&H utilized an approximate 3 ft length of sample tubing to collect a sample near the screen interval of the probe and utilized plastic sheeting to seal the top of the landfill gas probe during sample collection. Methane readings collected from the landfill gas probes are provided in Table 1. As shown in Table 1, methane was not detected in landfill gas probes LG-24 and LG-25. Landfill gas probe LG-23 contained a concentration of methane (3.4%), but the concentration detected is below the North Carolina Landfill Gas Monitoring Regulation (LGMR) of 5% methane by volume (100% of the LEL) for landfill property boundaries. Reduced oxygen and increased carbon monoxide concentrations detected by the GEM5000 during sampling indicate that representative landfill gas data were obtained. H&H reviewed the March 13, 2018 Remedial Action Post-Construction Monitoring Report prepared by Shield Engineering (Shield) documenting the screening results of landfill gas probes installed in the former Double Oaks Landfill which is the most recently available report. 9 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Charlotte Mecklenburg Housing Partnership - CHP/CHP-041 Double Oaks Methane/Report/Draft _Methane VMS Double Oaks Rev 1.doc Screening results during the previous sampling event conducted by Shield (January 5, 2018) indicated the presence of low-level methane in LG-24 (0.1 %) and LG-25 (1.3 %) below the LGMR of 5% methane by volume. Methane was not detected in LG-23 during the January 2018 sampling event. In addition, methane above 5% was not detected in these three monitoring points in multiple monitoring events in 2017 and 2018. Copies of the landfill gas monitoring map and summary tables prepared by Shield are provided in Appendix D. 10 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Charlotte Mecklenburg Housing Partnership - CHP/CHP-041 Double Oaks Methane/Report/Draft _Methane VMS Double Oaks Rev 1.doc 4.0 Summary and Recommendations On May 14 and 17, 2021, H&H conducted inspection and O&M activities on the MVMSs installed in eight (8) single family homes in the Brightwalk Phase 8 development in Charlotte, North Carolina. The Brightwalk Phase 8 development is part of the Double Oaks Brownfields Project (Brownfields Project No. 11037-01-060). The inspection activities conducted by H&H included: identifying system components, confirming system blower operation, confirming system vents were unobstructed, confirming the presence of methane sensors in each home and garage, and recording the manufacturing date of the methane sensors. Results of the inspection indicated that the MVMS blowers were operational for each home and the exhaust vents were unobstructed. During the inspection, H&H observed that several manometers were damaged and several methane sensors were missing and/or malfunctioning. Accordingly, H&H replaced the damaged manometers and missing sensors as part of the MVMS inspection. Following the MVMS inspection, DEQ conducted a site visit on May 21, 2021 to observe the MVMSs in select homes. H&H was present during the DEQ Site visit and assisted with coordination with access to the homes and identifying MVMS components. During the DEQ Site visit and at DEQ’s request, methane readings were collected from three landfill gas probes (LG-23, LG-24, and LG-25) installed along Woodward Ave. Methane was not detected above the 5% by volume (100% of the LEL) regulatory threshold for landfill property boundaries. In addition, methane above 5% was not detected in these three monitoring points in multiple monitoring events in 2017 and 2018. Recommendations  The methane sensors installed in the homes do not have a maximum methane concentration memory feature as specified in the MVMP. Because routine monitoring appears to have not been conducted and the methane sensors installed in the homes do not meet the specification in the design, H&H recommends conducting quarterly 11 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Charlotte Mecklenburg Housing Partnership - CHP/CHP-041 Double Oaks Methane/Report/Draft _Methane VMS Double Oaks Rev 1.doc inspections for a period of 1-year to observe the performance of the MVMS. The quarterly inspections will include the following:  Inspection of MVMS components as described in the approved MVMP.  Ambient air monitoring in each home utilizing a GEM5000 (or similar device).  The collection of methane samples from LG-23, LG-24, and LG-25 utilizing a GEM5000 methane gas detector (or similar device). H&H will install valved well caps on LG-23, LG-24, and LG-25 prior to collecting the methane samples.  H&H will further inspect the homes for the presence of sub-slab monitoring points. The quarterly inspection will include the collection differential pressure measurements and methane samples utilizing a GEM5000 (or similar device) from the sub-slab monitoring points (where present). If methane is not detected in the homes during the quarterly inspections and the MVMS is determined to be functioning, H&H will reduce the MVMS inspections to an annual basis. The annual MVMS inspections will be conducted in accordance with the annual inspection protocols described in the approved MVMP and also include the collection of methane samples from LG- 23, LG-24, and LG-25. H&H has confirmed with DreamKey that the Home Owners Association (HOA) for the Brightwalk Phase 8 Development has reserve funds for continued MVMS inspections and O&M.  H&H observed that some of the u-tube manometers installed on the MVMS blowers appeared to have lost fluid over time due to evaporation. Fluid loss may prevent accurate differential pressure readings during inspection events. Accordingly, H&H recommends replacing the u-tube manometers with differential pressure gauges. The differential pressure gauge will be a Dwyer Series 2-5005 Minihelic® II. The body of the differential 12 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Charlotte Mecklenburg Housing Partnership - CHP/CHP-041 Double Oaks Methane/Report/Draft _Methane VMS Double Oaks Rev 1.doc pressure gauge will be mounted inside the panel of the MVMS blower housing and the dial will be visible to residential occupants. A specification sheet for the proposed differential pressure gauge is included in Appendix E.    H&H observed that the vertical exhaust stacks were not installed with rain protection. H&H recommends opening the MVMS clean outs and observing for the potential presence of water in the accessible MVMS piping. If accumulated water is observed, H&H recommends removing the water and installing rain caps on the exhaust piping. Because it is anticipated that accumulated water in the MVMS is not impacted, water removed from the MVMS piping (if any) will be discharged to the surface.  The MVMP and methane sensor manufacturer recommends that sensors replaced after a period of 5-years. Several of the methane sensors are nearing their expiration date. Accordingly, H&H recommends replacing the sensors prior to the end of their 5-year service life.

NATIONWIDE.CASE NARRATIVE All sample aliquots were received at the correct temperature, in the proper containers, with the appropriate preservatives, and within method specified holding times, unless qualified or notated within the report. All MDL (LOD) and RDL (LOQ) values reported for environmental samples have been corrected for the dilution factor used in the analysis. All radiochemical sample results for solids are reported on a dry weight basis with the exception of tritium, carbon-14 and radon, unless wet weight was requested by the client. All Method and Batch Quality Control are within established criteria except where addressed in this case narrative, a non-conformance form or properly qualified within the sample results. By my digital signature below, I affirm to the best of my knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the quality of the data have been identified by the laboratory, and no information or data have been knowingly withheld that would affect the quality of the data.

NATIONWIDE.GLOSSARY OF TERMS Guide to Reading and Understanding Your Laboratory Report The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Abbreviations and Definitions MDL Method Detection Limit. ND Not detected at the Reporting Limit (or MDL where applicable). RDL Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. (S) Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description B The same analyte is found in the associated blank. J The identification of the analyte is acceptable; the reported value is an estimate. 1 Cp 2Tc 3Ss 4Cn 5Sr 6Qc 7Gl 8Al 9Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: GeoScience Group, Inc - NC CH17.0151.EV L960124 12/29/17 16:58 19 of 22 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: GeoScience Group, Inc - NC CH17.0151.EV L960124 12/29/17 17:04 19 of 22 ONE LAB.

NATIONWIDE.CASE NARRATIVE All sample aliquots were received at the correct temperature, in the proper containers, with the appropriate preservatives, and within method specified holding times, unless qualified or notated within the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples have been corrected for the dilution factor used in the analysis. All radiochemical sample results for solids are reported on a dry weight basis with the exception of tritium, carbon-14 and radon, unless wet weight was requested by the client. All Method and Batch Quality Control are within established criteria except where addressed in this case narrative, a non-conformance form or properly qualified within the sample results. By my digital signature below, I affirm to the best of my knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the quality of the data have been identified by the laboratory, and no information or data have been knowingly withheld that would affect the quality of the data.

NATIONWIDE.GLOSSARY OF TERMS Guide to Reading and Understanding Your Laboratory Report The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Abbreviations and Definitions MDL Method Detection Limit. ND Not detected at the Reporting Limit (or MDL where applicable). RDL Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. (S) Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description B The same analyte is found in the associated blank. J The identification of the analyte is acceptable; the reported value is an estimate. 1 Cp 2Tc 3Ss 4Cn 5Sr 6Qc 7Gl 8Al 9Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: GeoScience Group, Inc - NC CH17.0151.EV L961948 01/16/18 09:20 41 of 45 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: GeoScience Group, Inc - NC CH17.0151.EV L961948 01/16/18 09:40 41 of 45 ONE LAB.

This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Abbreviations and Definitions MDL Method Detection Limit. ND Not detected at the Reporting Limit (or MDL where applicable). RDL Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis.

PLUG-IN EXPLOSIVE GAS AND CARBON MONOXIDE ALARM WITH BATTERY BACK-UP AND SILENCE FEATURE USER’S MANUAL INSTALLATION WHERE TO INSTALL THIS ALARM For Gas Alarms, mounting depends on the type of explosive gas you intend to detect. Natural Gas (methane) is typically supplied through a main utility line connected to your home. If you do not live in a rural area you are likely to be a user of natural gas. Natural gas is a fossil fuel consisting mainly of Methane. Methane is much lighter than air and will rise rapidly in air. If you are a user of natural gas, the Alarm should be mounted between 6 and 12 inches (152mm and 305 mm) away from the ceiling (using cord feature) to ensure the earliest opportunity to detect a leak. Propane is typically supplied to homes by delivery truck in liquid form and stored near the home in propane tanks. Propane is used by homes in rural areas that do not have natural gas service. Since propane is the most commonly used Liquefied Petroleum Gas (LPG), propane and LP-Gas are often used synonymously. Unlike natural gas, propane is heavier than air and will collect at lower levels. If you are a user of propane, the Alarm should be mounted near the floor (using the direct plug-in feature) to ensure the earliest opportunity to detect a leak. Both propane and natural gas are colorless and odorless. For safety reasons, an ordorant (Mercaptan) is added so that any leak can be detected by smell. The common detection threshold for smelling the gases is around 20% of the Lower Explosion Limit (LEL). This can vary greatly depending on the individuals sense of smell and how long they have been exposed to it. The LEL of each of these gases defines the bottom range of flammability for the gas. Your Alarm is calibrated to sound before 25% of the LEL of either gas detected. Therefore, it is possible that you may smell gas before the Alarm is activated. If you are not sure which gas your home uses, contact your utility company. For CO Alarms, the National Fire Protection Association (NFPA) recommends that a CO Alarm should be centrally located outside of each separate sleeping area in the immediate vicinity of the bedrooms. For added protection, install additional CO Alarms in each separate bedroom, and on every level of your home. In general, install combination Explosive Gas and Carbon Monoxide Alarms: • WHERE YOU CAN HEAR THE ALARM FROM ALL SLEEPING AREAS • In or near bedrooms and living areas or wherever you suspect a gas or CO exposure is likely. • On each level of a multi-level home. Improper location can affect the sensitive electronic components in this Alarm. Please see “Where this Alarm Should Not Be Installed”. Recommended Placement DINING ROOM KITCHEN BEDROOM BEDROOM BEDROOMLIVING ROOM See “Avoiding Dead Air Spaces” for more information. NOTE: For any location, make sure no door or other obstruction could keep carbon monoxide or gas from reaching the Alarm. This unit should receive continuous electrical power. (The battery is meant for emergency back-up only). Choose an outlet where it can’t be accidentally unplugged or switched off by children. Keep small children away from the unit. Teach them not to play with it or unplug it. Explain what the alarms mean. 120VAC ~ 60Hz, 0.25 A IMPORTANT! PLEASE READ CAREFULLY AND SAVE. This user’s manual contains important information about your Smoke Alarm’s operation. If you are installing this Smoke Alarm for use by others, you must leave this manual—or a copy of it—with the end user. Model GC01CONFORMS TO UL STD 1484 and UL STD 2034 Printed in Mexico M08-0123-013 K1 5/16 3.875 inches 3.875 inchesMounting Guide Template 3 7/8 inches (98mm) WHAT TO DO IF EXPLOSIVE GAS IS DETECTED If you hear the alarm horn sound one beep per second, gas has been detected. The word GAS will be displayed. Evacuate everyone from the building. 1. Leave the house immediately, opening doors and windows as you leave. 2. Do not use your telephone or appliances. Do not turn any light switches off or on. Any spark or flame could ignite the gas. 3. Call 911 and your gas company from a phone that is away from your home. 4. Do not re-enter the area until the source of the leak is found and corrected. • If the unit alarms and you are not testing the unit, it is warning you of a potentially dangerous situation that requires your immediate attention. NEVER ignore any alarm. Ignoring the alarm may result in injury or death. • Never disconnect the power to quiet an unwanted alarm. Disconnecting the power disables the Alarm. This will remove your protection. Alarms have various limitations. See “General Limitations of Explosive Gas/CO Alarms” for details. IF THE CO ALARM SOUNDS: 1. Operate the Test/Silence button. 2. Call your emergency services, fire department or 911. Write down the number of your local emergency service here: _______________________________________________________________ 3. Immediately move to fresh air—outdoors or by an open door or window. Do a head count to check that all persons are accounted for. Do not re-enter the premises, or move away from the open door or window until the emergency services responder has arrived, the premises have been aired out, and your CO Alarm remains in its normal condition. 4. After following steps 1-3, if your CO Alarm reactivates within a 24-hour period, repeat steps 1-3 and call a qualified appliance technician to investigate for sources of CO from fuel-burning equipment and appliances, and inspect for proper operation of this equipment. If problems are identified during this inspection have the equipment serviced immediately. Note any combustion equipment not inspected by the technician, and consult the manufacturers’ instructions, or contact the manufacturers directly, for more information about CO safety and this equipment. Make sure that motor vehicles are not, and have not, been operating in an attached garage or adjacent to the residence. Write down the number of a qualified appliance technician here: _______________________________________________________________ IF YOUR GAS/CO ALARM SOUNDS WHAT TO DO IF CARBON MONOXIDE IS DETECTED Actuation of your CO Alarm indicates the presence of carbon monoxide (CO) which can kill you. In other words, when your CO Alarm sounds, you must not ignore it! USING THE SILENCE FEATURES NEVER disconnect the power to your Alarm to silence the horn—use the Silence Feature. Disconnecting the Alarm removes your protection! • The Silence Feature is intended to temporarily silence the horn while you identify and correct the problem. • To use the Silence Feature, press the Test/Silence button until the horn is silent. • If the Test/Silence button is pressed while the Alarm is in the silence mode, the alarm will start sounding again. When the GAS Alarm is silenced... The Alarm will remain silent for approximately 2 minutes and then return to normal operation. If the gas has not cleared within the silence period, the unit will go back into alarm. When the CO Alarm is silenced... The CO Alarm will remain silent for up to 4 minutes. While the Alarm is silenced, it will continue to monitor the air for CO. After 4 minutes, if CO levels remain potentially dangerous the horn will start sounding again. The Silence Feature is intended to temporarily silence the Alarm horn. It will not correct a CO or gas problem. SILENCING THE LOW BATTERY WARNING This Silence Feature can temporarily quiet the low battery warning “chirp” for up to 8 hours if AC power is present. You can silence the low battery warning “chirp” by pressing the Test/Silence button on the Alarm cover until you see the Green LED flicker, acknowledging the button-press. The display will flash “SILENCE” for 8 hours while the low battery warning “chirp” silence feature is activated. After 8 hours, the low battery “chirp” will resume. The Alarm will continue to operate as long as AC power is supplied. However, replace the battery as soon as possible, to maintain protection in event of a power outage. USING THE PEAK CO MEMORYThe CO Memory Feature lets you check the highest level of CO recorded. To check CO Memory: 1. Press the Display button until the peak CO level is displayed. To clear CO Memory: 1. Automatically resets after 24 hours. 2. a. While checking CO memory, press or hold the Display button until “CLEAR” is displayed. b. Press or hold the Display button until the CO Memory is cleared. 3. Remove all power; unplug the Alarm and remove the battery. NOTE: The highest CO level will be saved for 24 hours. DO NOT clear the CO Memory reading if you plan to call someone to investigate a CO problem! Clear the CO Memory reading only after the investigator has checked your home. If the investigator will not arrive within the 24 hour time period before the unit automatically resets, be sure to write down the peak level. SILENCING THE END OF LIFE SIGNAL This silence feature can temporarily quiet the End of Life warning “chirp” for up to 2 days. You can silence the End of Life warning “chirp” by pressing the Test/Silence button. The horn will chirp, acknowledging that the End of Life silence feature has been activated. After approximately 2 days, the End of Life “chirp” will resume. POTENTIAL SOURCES OF CO IN THE HOME Fuel-burning appliances like: portable heater, gas or wood burning fireplace, gas kitchen range or cooktop, gas clothes dryer. Damaged or insufficient venting: corroded or disconnected water heater vent pipe, leaking chimney pipe or flue, or cracked heat exchanger, blocked or clogged chimney opening. Improper use of appliance/ device: operating a barbecue grill or vehicle in an enclosed area (like a garage or screened porch). Transient CO Problems: “transient” or on-again-off-again CO problems can be caused by outdoor conditions and other special circumstances. The following conditions can result in transient CO situations: 1. Excessive spillage or reverse venting of fuel appliances caused by outdoor conditions such as: • Wind direction and/or velocity, including high, gusty winds. Heavy air in the vent pipes (cold/humid air with extended periods between cycles). • Negative pressure differential resulting from the use of exhaust fans. • Several appliances running at the same time competing for limited fresh air. • Vent pipe connections vibrating loose from clothes dryers, furnaces, or water heaters. • Obstructions in or unconventional vent pipe designs which can amplify the above situations. 2. Extended operation of unvented fuel burning devices (range, oven, fireplace). 3. Temperature inversions, which can trap exhaust close to the ground. 4. Car idling in an open or closed attached garage, or near a home. These conditions are dangerous because they can trap exhaust in your home. Since these conditions can come and go, they are also hard to recreate during a CO investigation. HOW CAN I PROTECT MY FAMILY FROM CO POISONING?A Gas/CO Alarm is an excellent means of protection. It monitors the air and sounds a loud alarm before Carbon Monoxide levels become threatening for average, healthy adults. A Gas/CO Alarm is not a substitute for proper maintenance of home appliances. To help prevent CO problems and reduce the risk of CO poisoning: • Clean chimneys and flues yearly. Keep them free of debris, leaves, and nests for proper air flow. Also, have a professional check for rust and corrosion, cracks, or separations. These conditions can prevent proper air movement and cause backdrafting. Never “cap” or cover a chimney in any way that would block air flow. • Test and maintain all fuel-burning equipment annually. Many local gas or oil companies and HVAC companies offer appliance inspections for a nominal fee. • Make regular visual inspections of all fuel-burning appliances. Check appliances for excessive rust and scaling. Also check the flame on the burner and pilot lights. The flame should be blue. A yellow flame means fuel is not being burned completely and CO may be present. Keep the blower door on the furnace closed. Use vents or fans when they are available on all fuel-burning appliances. Make sure appliances are vented to the outside. Do not grill or barbecue indoors, or in garages or on screen porches. • Check for exhaust backflow from CO sources. Check the draft hood on an operating furnace for a backdraft. Look for cracks on furnace heat exchangers. • Check the house or garage on the other side of shared wall. • Keep windows and doors open slightly. If you suspect that CO is escaping into your home, open a window or a door. Opening windows and doors can significantly decrease CO levels. In addition, familiarize yourself with all enclosed materials. Read this manual in its entirety, and make sure you understand what to do if your Gas/CO Alarm sounds.

END OF LIFE LED flashing Green 5 times in sync with 5 chirps 5 chirps every minute “End” is displayed. WHERE THIS ALARM SHOULD NOT BE INSTALLED To avoid causing damage to the unit, to provide optimum protection, and to prevent unnecessary alarms, Do NOT locate this Alarm: • In garages, kitchens, crawl spaces and unfinished attics. Avoid extremely dusty, dirty or greasy areas. Installation in these areas could lead to nuisance alarms, may expose the sensor to substances that could damage or contaminate it, or the Alarm may not be heard by persons in other areas of the home, especially if they are sleeping. • In the garage, vehicle exhaust can contain some carbon monoxide. These levels are higher when the engine is first started. Within hours of starting a vehicle and backing it out of the garage, the levels present over time can activate the Alarm and become a nuisance. • In the kitchen, some gas appliances can emit a short burst of CO or gas upon start-up. This is normal. If your Explosive Gas/CO Alarm is installed too close to these appliances, it may alarm often and become a nuisance. • Keep units at least 20 feet (6 meters) from the sources of combustion particles (stove, furnace, water heater, space heater) if possible. In areas where a 20-foot (6m) distance is not possible – in modular, mobile, or smaller homes, for example – it is recommended the Alarm be placed as far from these fuel-burning sources as possible. The placement recommendations are intended to keep these Alarms at a reasonable distance from a fuel-burning source, and thus reduce “unwanted” alarms. Unwanted alarms can occur if an Alarm is placed directly next to a fuel-burning source. Ventilate these areas as much as possible. If you must install the Alarm near a cooking or heating appliance, install at least 5 feet (1.5 meters) from appliance. • In extremely humid areas. This Alarm should be at least 10 feet (3 meters) from a shower, sauna, humidifier, vaporizer, dishwasher, laundry room, utility room, or other source of high humidity. • In direct sunlight. • In turbulent air, like near ceiling fans or open windows. Blowing air may prevent CO or gas from reaching the sensors. • In areas where temperature is colder than 40˚ F (4.4˚ C) or hotter than 100˚ F (37.8˚ C). These areas include non-airconditioned crawl spaces, unfinished attics, uninsulated or poorly insulated ceilings, porches, and garages. • Less than 12 inches (305 mm) away from fluorescent lights. Electrical “noise” can interfere with the sensor. • In “dead air” spaces. See “Avoiding Dead Air Spaces”. AVOIDING DEAD AIR SPACES “Dead air” spaces may prevent gas from reaching the Alarm. To avoid dead air spaces, follow installation recommendations below. On ceilings, install Alarms as close to the center of the ceiling as possible. If this is not possible, install the Alarm at least 4 inches (102 mm) from the wall or corner. For wall mounting, the top edge of Alarms should be placed between 6 inches (152 mm) and 12 inches (305 mm) from the wall/ceiling line. On a peaked, gabled, or cathedral ceiling, install Alarm within 3 feet (0.9 meters) of the peak of the ceiling, measured horizontally. BEFORE YOU BEGIN INSTALLATIONSince CO generally mixes well with air, mounting the Alarm will depend on the type of explosive gas you intend to detect. If you are not certain which type of gas you are using in your home, please read about natural gas and propane in “Where to Install this Alarm”. • Make sure the alarm is not receiving excessively noisy power. Examples of noisy power could be major appliances on the same circuit, power from a generator or solar power, light dimmer on the same circuit or mounted near fluorescent lighting. Excessively noisy power may cause damage to your Alarm. Find the pair of self-adhesive labels included with this Gas/CO Alarm. • On each label write in the phone number of your emergency responder (like 911) and a qualified appliance technician. • Place one label near the Gas/CO Alarm, and the other label in the “fresh air” location you plan to go if the alarm sounds. HOW TO INSTALL THIS GAS/CO ALARMIMPORTANT! Read all instructions before using this product. Tools you will need: Screwdriver, drill. 1. Determine the best location for your Gas/CO Alarm. 2. Your Alarm is equipped to be mounted as a corded unit (recommended for natural gas detection), a direct plug unit (recommended for propane gas detection). The unit can be plugged directly into a wall outlet. If your outlets are mounted horizontally, refer to “If Outlet is Mounted Horizontally (Sideways)” If the adapter is taken out of the unit, the Alarm can be installed high on the wall, while the adapter is plugged into a wall outlet. The explosive gas you use will determine if the Alarm should be installed high on the wall (AC cord option) or low on the wall (direct plug option). ACTIVATING THE BATTERY BACK-UP Activate the battery back-up by installing the battery. The battery is for back-up only and is not intended to power the Alarm for an extended period of time in the absence of AC. The Alarm will light-up the display briefly to indicate the unit is receiving power. DIRECT PLUG ALARM INTO AN OUTLET (FOR PROPANE DETECTION) This Alarm can be plugged directly into a wall outlet located close to the floor. This is the recommended configuration for detecting propane. 1. Choose a standard UNSWITCHED 120V AC outlet. 2. Plug Alarm in. IF OUTLET IS MOUNTED HORIZONTALLY (SIDEWAYS)` If you are going to use your Alarm as a direct plug into an outlet that is mounted horizontally (sideways), you may want to rotate the adapter 90º, as follows: 1. With back of unit facing you (AC blades on your left), place your left thumb on adapter release and grab AC blades with your right hand to release the left side. 2. Repeat for the other side adapter thumb release. This will allow adapter to slide out. 3. Remove adapter. 4. Rotate the adapter 90º and snap firmly back into place. 5. Plug Alarm into AC outlet. SECURING THE POWER CORD TO AN OUTLET DISCONNECT POWER TO THE OUTLET TO AVOID ELECTRICAL SHOCK. 1. Remove the wallplate screw from the outlet and hold the wallplate in position. 2. Plug the power cord into the wall outlet so that the screw hole lines up with the wallplate screw hole. 3. Insert the screw through the power cord screw hole and into the wallplate screw hole. 4. Tighten screw in place and restore power to the outlet. WALL MOUNTED ALARM (FOR NATURAL GAS DETECTION) Installation tips for power cord models: The power cord option provides more flexibility in mounting locations and allows the Alarm to be easily installed at or above eye level. NOTE: If you mount the Alarm high on a wall, make sure it is between 6 to 12 inches (152-305 mm) down from the ceiling. Any higher than this, it will be in “dead air” space and carbon monoxide or natural gas may not reach the sensors. NOTE: Do not cover the Alarm with a curtain. To install for a wall-mount, you will need to pull out the removable adapter and power cord, as follows: 1. 1. Repeat steps 1 to 3 as described above in “to rotate the adapter”. 2. With adapter out, pull out power cord and unwrap it. 3. Insert the screws provided until head is approx. 1/8 inch (3 mm) from wall (if mounting in plaster board or drywall, drill 3/16 inch (5 mm) hole and use plastic anchor provided). Use mounting guide template to locate holes as shown in diagram below. 4. Hook the Alarm over the screw onto the keyhole in back of unit. 5. Plug power cord into AC outlet. TEST THE ALARM 1. Make sure the Alarm is receiving AC power. Under normal operation, the Green indicator light will shine continuously. If the Green power indicator light does not light, recheck connections. If connections are correct and the Green power indicator still does not light, the unit should be replaced immediately. 2. Press and hold the test button until the alarm sounds. You will hear the signal that indicates the presence of explosive gas followed by the signal for carbon monoxide. When testing the Alarm, have someone else check that the Alarm can be heard easily from the sleeping areas. The unit should be located where it can wake you if it alarms at night. 1. Test/Silence Button: Press and hold to activate test, or to silence the alarm. 2. POWER Light (GREEN) 3. Display 4. (Behind the Cover) Alarm Horn: 85 dB audible alarm for test, alarm, and unit malfunction warning. 5. Display Button: Press to recall highest CO level recorded 6. Battery Compartment 23 4 1 5 6 HOW YOUR ALARM WORKS THE COVER OF YOUR ALARM REGULAR MAINTENANCE This unit has been designed to be as maintenance-free as possible, but there are a few simple things you must do to keep it working properly: • Test it at least once a week. • Clean the Alarm at least once a month; gently vacuum the outside of the Alarm using your household vacuum’s soft brush attachment. Test the Alarm. Never use water, cleaners or solvents since they may damage the unit. • Relocate the unit if it sounds frequent unwanted alarms. See “Where This Alarm Should Not Be Installed” for details. • When the battery back-up becomes weak, the Alarm will “chirp” about once a minute (the low battery warning). You should replace the battery immediately to continue your protection. This Alarm must have AC or battery power to operate. If AC power fails, and the battery is dead or missing, the Alarm cannot operate. DO NOT spray cleaning chemicals or insect sprays directly on or near the Alarm. DO NOT paint over the Alarm. Doing so may permanently damage the Alarm. CHOOSING A REPLACEMENT BATTERY: Your Alarm requires one standard 9V alkaline battery. The following batteries are acceptable as replacements: Duracell #MN1604, (Ultra) #MX1604; Eveready (Energizer) #522. These batteries are available at many local retail stores. • Always use the exact batteries specified by this User’s Manual. DO NOT use rechargeable batteries. Clean the battery contacts and also those of the device prior to battery installation. Install batteries correctly with regard to polarity (+ and -). • Please dispose of or recycle used batteries properly, following any local regulations. Consult your local waste management authority or recycling organization to find an electronics recycling facility in your area. DO NOT DISPOSE OF BATTERIES IN FIRE. BATTERIES MAY EXPLODE OR LEAK. • Keep battery out of reach of children. In the event a battery is swallowed, immediately contact your poison control center, your physician, or the National Battery Ingestion hotline at 202-625-3333 as serious injury may occur. Actual battery service life depends on the Alarm and the environment in which it is installed. All the batteries specified above are acceptable replacement batteries for this unit. Regardless of the manufacturer’s suggested battery life, you MUST replace the battery immediately once the unit starts “chirping” (the “low battery warning”). WHAT YOU NEED TO KNOW ABOUT CO WHAT IS CO?CO is an invisible, odorless, tasteless gas produced when fossil fuels do not burn completely, or are exposed to heat (usually fire). Electrical appliances typically do not produce CO. These fuels include: Wood, coal, charcoal, oil, natural gas, gasoline, kerosene, and propane. Common appliances are often sources of CO. If they are not properly maintained, are improperly ventilated, or malfunction, CO levels can rise quickly. CO is a real danger now that homes are more energy efficient. “Air-tight” homes with added insulation, sealed windows, and other weatherproofing can “trap” CO inside. SYMPTOMS OF CO POISONINGThese symptoms are related to CO POISONING and should be discussed with ALL household members. Mild Exposure: Slight headache, nausea, vomiting, fatigue (“flu-like” symptoms). Medium Exposure: Throbbing headache, drowsiness, confusion, fast heart rate. Extreme Exposure: Convulsions, unconsciousness, heart and lung failure. Exposure to Carbon Monoxide can cause brain damage, death. Some individuals are more sensitive to CO than others, including people with cardiac or respiratory problems, infants, unborn babies, pregnant mothers, or elderly people can be more quickly and severely affected by CO. Members of sensitive populations should consult their doctors for advice on taking additional precautions. FINDING THE SOURCE OF CO AFTER AN ALARMCarbon monoxide is an odorless, invisible gas, which often makes it difficult to locate the source of CO after an alarm. These are a few of the factors that can make it difficult to locate sources of CO: • House well ventilated before the investigator arrives. • Problem caused by “backdrafting.” • Transient CO problem caused by special circumstances. Because CO may dissipate by the time an investigator arrives, it may be difficult to locate the source of CO. BRK Brands, Inc. shall not be obligated to pay for any carbon monoxide investigation or service call. REGULATORY INFORMATION FOR EXPLOSIVE GAS/CO ALARMS REGULATORY INFORMATION FOR CO ALARMS UNDERWRITERS LABORATORIES INC. UL2034 WHAT LEVELS OF CO CAUSE AN ALARM? Underwriters Laboratories Inc. Standard UL2034 requires residential CO Alarms to sound when exposed to levels of CO and exposure times as described below. They are measured in parts per million (ppm) of CO over time (in minutes). UL2034 Required Alarm Points*: • If the alarm is exposed to 400 ppm of CO, IT MUST ALARM BETWEEN 4 and 15 MINUTES. • If the alarm is exposed to 150 ppm of CO, IT MUST ALARM BETWEEN 10 and 50 MINUTES. • If the alarm is exposed to 70 ppm if CO, IT MUST ALARM BETWEEN 60 and 240 MINUTES. Approximately 10% COHb exposure at levels of 10% to 95% Relative Humidity (RH). The unit is designed not to alarm when exposed to a constant level of 30 ppm for 30 days. CO Alarms are designed to alarm before there is an immediate life threat. Since you cannot see or smell CO, never assume it’s not present.• An exposure to 100 ppm of CO for 20 minutes may not affect average, healthy adults, but after 4 hours the same level may cause headaches. • An exposure to 400 ppm of CO may cause headaches in average, healthy adults after 35 minutes, but can cause death after 2 hours. This CO Alarm measures exposure to CO over time. It alarms if CO levels are extremely high in a short period of time, or if CO levels reach a certain minimum over a long period of time. The CO Alarm generally sounds an alarm before the onset of symptoms in average, healthy adults.Why is this important? Because you need to be warned of a potential CO problem while you can still react in time. In many reported cases of CO exposure, victims may be aware that they are not feeling well, but become disoriented and can no longer react well enough to exit the building or get help. Also, young children and pets may be the first affected. The average healthy adult might not feel any symptoms when the CO Alarm sounds. However, people with cardiac or respiratory problems, infants, unborn babies, pregnant mothers, or elderly people can be more quickly and severely affected by CO. If you experience even mild symptoms of CO poisoning, consult your doctor immediately! Standards: Underwriters Laboratories Inc. Single and Multiple Station carbon monoxide alarms UL2034. According to Underwriters Laboratories Inc. UL2034, Section 1-1.2: “Carbon monoxide alarms covered by these requirements are intended to respond to the presence of carbon monoxide from sources such as, but not limited to, exhaust from internal-combustion engines, abnormal operation of fuel-fired appliances, and fireplaces. CO Alarms are intended to alarm at carbon monoxide levels below those that could cause a loss of ability to react to the dangers of Carbon Monoxide exposure.” This CO Alarm monitors the air at the Alarm, and is designed to alarm before CO levels become life threatening. This allows you precious time to leave the house and correct the problem. This is only possible if Alarms are located, installed, and maintained as described in this manual. Gas Detection at Typical Temperature and Humidity Ranges: The CO Alarm is not formulated to detect CO levels below 30 ppm typically. UL tested for false alarm resistance to Methane (500 ppm), Butane (300 ppm), Heptane (500 ppm), Ethyl Acetate (200 ppm), Isopropyl Alcohol (200 ppm) and Carbon Dioxide (5000 ppm). Values measure gas and vapor concentrations in parts per million. Audible Alarm: 85 dB minimum at 10 feet (3 meters). REGULATORY INFORMATION FOR EXPLOSIVE GAS ALARMS Standards: Underwriters Laboratories Inc. UL1484. According to Underwriters Laboratories Inc. UL1484, this unit meets the alarm response time for gas as follows: This unit shall alarm before 25% of the LEL of either natural gas or propane is detected. In all cases, the unit will detect gas as a priority over carbon monoxide. If the device is detecting CO, then detects an amount of gas to cause an alarm, the device will stop alarming for CO and begin to alarm for gas. GENERAL LIMITATIONS OF EXPLOSIVE GAS/CO ALARMS This Gas/CO Alarm is intended for residential use. It is not intended for use in industrial applications where Occupational Safety and Health Administration (OSHA) requirements for Carbon Monoxide Alarms must be met. This device is not intended to alert hearing impaired residents. Gas/CO Alarms may not waken all individuals. If children or others do not readily waken to the sound of the Gas/CO Alarm, or if there are infants or family members with mobility limitations, make sure that someone is assigned to assist them in the event of an emergency. This Gas/CO Alarm will not sense gas or CO that does not reach the sensors. It will only sense gas or CO at the sensor. Gas or CO may be present in other areas. Doors or other obstructions may affect the rate at which CO or gas reaches the sensors. Gas/CO Alarms may not be heard. The alarm horn loudness meets or exceeds current UL standards of 85 dB at 10 feet (3 meters). However, if the Gas/CO Alarm is installed outside the bedroom, it may not wake up a sound sleeper or one who has recently used drugs or has been drinking alcoholic beverages. This is especially true if the door is closed or only partly open. Even persons who are awake may not hear the alarm horn if the sound is blocked by distance or closed doors. Noise from traffic, stereo, radio, television, air conditioner, or other appliances may also prevent alert persons from hearing the alarm horn. This Gas/CO Alarm is not intended for people who are hearing impaired. This Gas/CO Alarm is not a substitute for life insurance. Though this Gas/CO Alarm warns against increasing CO levels or the presence of gas, BRK Brands, Inc. does not warrant or imply in any way that they will protect lives. Homeowners and renters must still insure their lives. This Gas/CO Alarm is not foolproof. Like all other electronic devices, this Gas/CO Alarm has limitations. It can only detect gas or CO that reaches the sensors. It may not give early warning of the source of gas or CO is in a remote part of the home, away from the alarm device. This Gas/CO Alarm has a limited life. Although this Gas/CO Alarm and all of its parts have passed many stringent tests and are designed to be as reliable as possible, any of these parts could fail at any time. Therefore, you must test this device weekly. The unit should be replaced immediately if it is not operating properly.

INSTALACIÓN DÓNDE INSTALAR ESTE DETECTORPara detectores de Gas, el montaje depende del tipo de gas explosivo que pretenda detectar. Gas Natural (metano), se lo suministra típicamente a través de un tubo de servicio principal conectado a su hogar. Si no vive en una zona rural es muy probable que sea usuario de gas natural. El gas natural es un combustible fósil que consiste principalmente de metano. El metano es mucho más liviano que el aire y se elevará rápidamente en él. Si es usuario de gas natural, el detector debe montarse entre 152mm y 305 mm (6 y 12 pulgadas) separado del cielorraso (usando el modelo con cable) para asegurar la rápida detección de fugas. El Propano es típicamente suministrado a los hogares en estado líquido por camiones repartidores y almacenado en tanques de propano cercanos a las casas. El Propano se usa en hogares ubicados en zonas rurales que no poseen servicio de gas natural. Como el propano es el Gas de Petróleo Licuado (GPL) más usado, Propano y Gas Licuado de Petróleo son frecuentemente usados como sinónimos. A diferencia del gas natural, el propano es más pesado que el aire y se acumula cerca del suelo. Si es usuario de propano, el detector debe ser montado cerca del suelo (usando el modelo para enchufar) para asegurar la rápida detección de fugas. El propano y el gas natural son ambos incoloros e inodoros. Por razones de seguridad, se les incorpora una sustancia odorífera (Mercaptan) para poder detectar cualquier fuga mediante el olfato. El umbral de detección usado para oler los gases es de aproximadamente un 20% del Limite Inferior de Explosión (LIE). Esto puede variar ampliamente dependiendo del sentido del olfato de cada individuo y de cuanto tiempo han estado expuestos al gas. El LIE de cada uno de estos gases define el rango inferior de inflamabilidad del gas. Su detector está calibrado para activarse antes del 25% del LIE de cualquiera de los gases. Por lo tanto, es posible que halla olor a gas antes de que se active la alarma. Si no está totalmente seguro de que tipo de gas usa en su hogar, contacte a la compañía de servicios. En el caso de los detectores de CO, la Asociación Nacional de Protección contra Incendios (NFPA) recomienda que el detector de CO tenga una ubicación central fuera de cada área de dormitorios, en proximidad inmediata a las recámaras. Para mayor protección, instale detectores de CO en cada recámara independiente y en cada nivel de su casa. En general, instale los detectores combinados de gas explosivo y monóxido de carbono: • DE MODO QUE PUEDA ESCUCHAR LA SIRENA DESDE LOS DORMITORIOS • En o cerca de los dormitorios y zonas habitadas o donde sospeche que será probable quedar expuesto al CO. • En cada nivel de una casa con varios niveles. Una ubicación incorrecta puede afectar los sensibles componentes electrónicos de este detector. Por favor consulte la sección “Dónde no instalar este detector”. Ubicaciones recomendadas COMEDOR COCINA DORMITORIOS DORMITORYSALA DE ESTAR Si desea más información, consulte “Cómo evitar espacios con aire viciado”. NOTA: Para cualquier ubicación, cerciórese de que ninguna puerta u otra obstrucción pueda impedir que el monóxido de carbono o el gas lleguen al detector. Esta unidad debe recibir alimentación eléctrica ininterrumpidamente (use la batería sólo como respaldo de emergencia). Elija un tomacorriente donde no pueda ser desconectado accidentalmente o apagado por los niños. Mantenga a los niños lejos del detector. Enséñeles a no jugar con él ni desconectarlo. Explíqueles lo que significan las alarmas. © 2016 BRK Brands, Inc. Todos los derechos reservados.

Modelo GC01CUMPLE CON LA NORMAS UL 1484 Y UL 2034 Impreso en Mexico M08-0123-013 K1 5/16 DÓNDE NO INSTALAR ESTE DETECTOR Para evitar dañar la unidad, para protegerla y prevenir falsas alarmas, NO ubique este detector en: • Garajes, cocinas, espacios donde los bebés gatean y áticos sin terminar. Evite áreas extremadamente polvorientas, sucias o grasosas. Instalaciones en estas áreas conducen a alarmas con interferencias, pueden exponer el sensor a sustancias que podrían dañarlo o contaminarlo, o el detector podría no ser escuchado por personas que se encuentren en otras áreas de la casa, sobretodo si están durmiendo. • En el garaje, el gas de escape del vehículo puede contener algo de monóxido de carbono. Estos niveles son mayores cuando el motor recién arranca. Luego de varias horas de haber arrancado el vehículo y de haberlo sacado del garaje, los niveles remanentes pueden activar el detector y convertirse en una interferencia. • En la cocina, algunos artefactos a gas pueden emitir pequeñas ráfagas de CO o gas en el momento del encendido. Esto es normal. Si su detector de gas explosivo/CO es instalado demasiado cerca de estos artefactos, puede llegar a activarse frecuentemente y convertirse en una interferencia. • De ser posible, mantenga la unidad a una distancia mínima de 6 metros (20 pies) de las fuentes de partículas de combustión (estufas, calderas, calentadores de agua y calefactores). En las áreas donde no es posible respetar la distancia de 6 metros (20 pies) – por ejemplo, en casas modulares, móviles o pequeñas – se recomienda colocar el detector tan lejos como sea posible de estas fuentes de combustión. Las recomendaciones de ubicación tienen el propósito de mantener estos detectores a una distancia razonable de cualquier fuente de combustión y, de ese modo, reducir las alarmas “indeseadas”. Puede haber falsas alertas si el detector se encuentra muy cerca de alguna fuente de combustión. Ventile estos lugares lo mejor que pueda. Si debe instalar el detector cerca de un artefacto de cocina o calefacción, instálelo al menos a 1.5 metros (5 pies) del artefacto. • En sitios extremadamente húmedos. Este detector debe estar a por lo menos 3 metros (10 pies) de cualquier regadera, sauna, humidificador, vaporizador, lavavajillas, cuarto de lavado, cuarto de limpieza u otras fuentes de humedad. • Bajo la luz directa del sol. • En lugares con turbulencia de aire, como sucede en torno a los ventiladores de techo o las ventanas abiertas. Las corrientes de aire pueden impedir que el CO o el gas lleguen a los sensores. • En sitios donde la temperatura descienda a menos de 4,4° C (40° F) o se eleve por arriba de 37,8° C (100° F). Estos lugares incluyen pasadizos sin aire acondicionado, áticos sin terminar, techos con poco o ningún aislamiento, vestíbulos y garajes. • A menos de 305 mm (12 pulgadas) de las lámparas fluorescentes. La “interferencia” eléctrica puede interferir con el sensor. • En espacios con “aire viciado”. Vea “Cómo evitar espacios con aire viciado”. CÓMO EVITAR ESPACIOS CON AIRE VICIADO Los espacios con “aire viciado” pueden impedir que el gas llegue al detector de gas y CO. Para evitar espacios con aire viciado, apéguese a las recomendaciones siguientes. En los techos, instale los detectores tan cerca del centro del techo como sea posible. De no ser posible, instale el detector al menos a 102 mm (4 pulgadas) del muro o la esquina. Para adosarlos a un muro, el borde superior de los detectores debe quedar entre 102 mm (4 pulgadas) y 152 mm (6 pulgadas) del ángulo entre el muro y el techo. En un techo de dos aguas, con aleros o en forma de catedral, instale primero el detector a menos de 90 cm (3 pies) de la cúspide del techo, medidos horizontalmente. ANTES DE INICIAR LA INSTALACIÓNComo el CO generalmente se mezcla bien con el aire, el montaje del detector dependerá del tipo de gas explosivo que pretenda detectar. Si no está del todo seguro de que tipo de gas utiliza en su casa, por favor lea acerca del gas natural y propano en “Dónde instalar este detector”. • Cerciórese de que el detector no reciba un suministro eléctrico excesivamente fluctuante. Como ejemplos de suministro fluctuante pueden mencionarse la presencia de aparatos eléctricos grandes conectados al mismo circuito, la electricidad procedente de un generador o de fotoceldas solares, la presencia de un atenuador en el mismo circuito o que la unidad esté cerca de luminarias fluorescentes. El suministro eléctrico excesivamente fluctuante puede dañar su detector. Encuentre el par de etiquetas autoadheribles que se incluyen con este detector de gas y CO. • • Escriba en cada etiqueta el número de teléfono de emergencias de su localidad (por ejemplo, 911) y el de algún electricista calificado. • • Adhiera una etiqueta cerca del detector de gas y CO y la otra en el lugar con “aire fresco” en donde piense refugiarse en caso de que suene la alarma. CÓMO INSTALAR ESTE DETECTOR DE GAS/CO¡IMPORTANTE! Lea todas las instrucciones antes de usar este producto. Herramientas necesarias: Destornillador, taladro.1. Determine la mejor ubicación para su detector de Gas/CO. 2. Su detector está preparado para ser montado como unidad con cable (recomendado para detección de gas natural), o para enchufar directamente (recomendado para detección de gas propano). La unidad puede enchufarse directamente en un tomacorrientes. Si sus tomacorrientes están en posición horizontal, refiérase a “Si los tomacorrientes están en posición horizontal (lateral)”. 3. Si el adaptador se extrae de la unidad, el detector puede ser instalado a determinada altura sobre la pared, mientras que el detector está enchufado al tomacorrientes. El gas explosivo que utilice determinará si el detector debe estar alto sobre la pared (opción cable de AC) o bajo sobre la pared (opción de enchufe directo). ACTIVACION DE LA BATERÍA DE RESGUARDO Active la batería de resguardo instalando la batería. La batería es sólo para resguardo y no está pensada para energizar el detector por un período largo de tiempo en ausencia de CA. El detector encenderá brevemente la pantalla para indicar que la unidad está recibiendo energía. ENCHUFAR DIRECTAMENTE EL DETECTOR A UN TOMACORRIENTES (para detección de propano) Este detector se puede enchufar directamente a un tomacorrientes ubicado cerca del piso. Esta es la configuración recomendada para la detección de propano. 1. Elija un tomacorrientes estándar NO CONMUTADO de 120V CA. 2. Enchufe allí la alarma. SI EL TOMACORRIENTES ESTA MONTADO HORIZONTALMENTE (LATERAL) Si va a usar su detector como un enchufe directo en un tomacorrientes que está montado horizontalmente (lateral), puede desear rotar el adaptador 90º, de la siguiente forma: 1. Con la parte trasera de la unidad mirando hacia Ud. (las clavijas de CA a su izquierda), coloque su pulgar izquierdo sobre el desenganche del adaptador y tome las clavijas de CA con su mano derecha para desenganchar el lado izquierdo. 2. Repita la operación para el desenganche del otro lado. Esto permitirá que el adaptador se desplace hacia afuera. 3. Retire el adaptador. 4. Gire el adaptador 90º y engánchelo firmemente en su lugar. 5. Enchufe el detector en el tomacorrientes de CA. DETECTOR MONTADO EN PARED (para detección de Gas Natural) Consejos de instalación para modelos con cable: La opción con cable brinda mayor flexibilidad de ubicación y permite instalar el detector fácilmente al nivel de los ojos o por encima de él. NOTA: Si instala el detector en la pared, asegúrese de que quede a una distancia de 152 a 305 mm (6 a 12 pulgadas) del cielorraso. Si lo ubica por encima de este nivel, estará en un espacio con “aire viciado” y el monóxido de carbono o gas natural puede no llegar a los sensores. NOTA: No cubra el detector con una cortina. Para instalarlo en pared, deberá extraer el adaptador desmontable y el cable, de la siguiente forma: 1. Repita los pasos 1 a 3 descriptos arriba en “para rotar el adaptador”. 2. Con el adaptador afuera, extraiga y desenrolle el cable. 3. Introduzca los tornillos provistos hasta que la cabeza esté a aprox. 3 mm (1/8”) de la pared (si el montaje se realiza en paneles de yeso o drywall, perfore un agujero de 5 mm (3/16“) y utilice el anclaje plástico provisto). Use la plantilla guía de montaje para ubicar los agujeros como muestra el diagrama de abajo. 4. Enganche el detector en los tornillos usando las caladuras de la parte trasera. 5. Enchufe el cable de alimentación en el tomacorrientes de CA. 1. Botón de Test/Silence (Prueba/Silencio): Presione y mantenga oprimido para iniciar la prueba o para silenciar la alarma 2.

Después de seguir los pasos 1 a 3, si su detector de gas y CO se vuelve a activar en menos de 24 horas, repita los pasos 1 a 3 y llame a un experto en equipos domésticos para que investigue cuál de sus equipos y aparatos de combustión es la fuente de CO y asegúrese de que tales equipos funcionen correctamente. Si se identificaran problemas durante esta inspección, haga que reparen de inmediato el equipo. Tome nota de cualquier equipo de combustión que no haya sido inspeccionado por el técnico y consulte los instructivos del fabricante o bien, comuníquese directamente con el fabricante para obtener mayor información sobre seguridad en cuanto al CO y dicho equipo. Cerciórese de que no existan o hayan existido vehículos automotores en marcha en el garaje o junto a la residencia. Anote aquí el número de teléfono de un técnico experto en equipos domésticos: _____________________________________________________________ ¿QUÉ HACER SI SE DETECTA GAS EXPLOSIVO? Si escucha sonar la sirena con un pitido por segundo, significa que se ha detectado gas. La palabra GAS será presentada en pantalla. Evacue a todas las personas que estén dentro de las instalaciones. 1. Abandone la casa inmediatamente, dejando puertas y ventanas abiertas. 2. No utilice su teléfono o artefactos del hogar. No apague ni encienda ningún interruptor de luz. Cualquier chispa o llama puede encender el gas. 3. Llame al 911 y a la compañía de gas desde un teléfono alejado de su casa. 4. No vuelva a ingresar al área hasta que la fuente de pérdida sea identificada y reparada. • Si la unidad suena la alarma y usted no está probándola, esto le advierte de una situación potencialmente peligrosa que requiere atención inmediata. JAMÁS ignore una alarma. Ignorar la alarma puede dar por resultado lesiones e incluso la muerte.• Nunca desconecte la alimentación para silenciar una alarma no deseada. Desconectando la alimentación se desactiva el detector. Esto lo dejará sin protección. Los detectores tienen diversas limitaciones. Consulte “Limitaciones generales de los detectores de gas explosivo y CO” para obtener detalles. USO DE LA FUNCIÓNS DE SILENCIAMIENTO JAMÁS interrumpa el suministro de electricidad hacia su detector de gas y CO para silenciar la bocina; utilice la función de silenciamiento. ¡Desconectar el detector le deja sin protección!• La función de silenciamiento tiene por objeto callar temporalmente la bocina mientras usted identifica y corrige el problema. • Para activar la función de silenciamiento, presione el botón Test/Silence hasta que la sirena se apague. • Si el botón Test/Silence es presionado mientras el detector está silenciado, la sirena comenzará a sonar nuevamente. CUANDO SE SILENCIA UN DETECTOR DE GAS... La sirena permanecerá en silencio por aproximadamente 2 minutos y luego volverá a operar normalmente. Si el gas no se ha despejado durante el período de silencio, la unidad volverá a dar la alarma. CUANDO SE SILENCIA UN DETECTOR DE CO... El detector de CO permanecerá en silencio durante un máximo de 4 minutos. Mientras el detector esté silente, continuará detectando la presencia de CO en el aire. Luego de 4 minutos, si las concentraciones de CO siguen siendo potencialmente peligrosas la bocina empezará a sonar de nuevo. La función de silenciamiento tiene por objeto acallar temporalmente la bocina del detector. No corregirá el problema de gas/CO. SILENCIAMIENTO DE LA ADVERTENCIA DE BATERÍA DESCARGADALa Opción de Silencio puede silenciar temporariamente el “chirrido” de advertencia de batería descargada por un período de hasta 8 horas si el suministro de CA está presente. Puede silenciar el “chirrido” de advertencia de batería descargada presionando el botón Test/Silence en el frente del detector hasta que vea parpadear el LED Verde, reconociendo la presión del botón. En la pantalla parpadeará “SILENCIO” por 8 horas mientras esté activada la opción de silenciamiento del “chirrido” de advertencia de batería descargada. Pasadas las 8 horas, el “chirrido” de batería descargada se reanuda. El detector seguirá operando mientras tenga suministro de CA. Sin embargo es conveniente reemplazar la batería lo más pronto posible, para mantener la protección en caso de corte de energía. CÓMO USAR LA OPCIÓN DE MEMORIA DE CO PICOLa característica de memoria de CO permite comprobar el más alto nivel de CO registrado.Para revisar la memoria de CO: 1. Presione el botón de visualización hasta que aparezca el nivel pico de CO. Para borrar la memoria de CO: 1. Se restablece automáticamente después de 24 horas.2. a. Mientras verifica la memoria de CO, mantenga presionado el botón de visualización hasta que aparezca “BORRAR”. b. Mantenga presionado el botón de visualización hasta que se borre la memoria de CO. 3. Desconecte toda la alimentación eléctrica, desenchufe el detector y retire la batería. NOTA: El nivel máximo de CO se memoriza por 24 horas. ¡NO borre la lectura de la memoria de CO si piensa llamar a alguien para investigar un problema de CO! Borre la lectura de la memoria de CO sólo después de que el investigador haya revisado su vivienda. Si el investigador no va a llegar dentro del período de 24 horas previo al restablecimiento automático de la unidad, asegúrese de anotar el nivel máximo. CÓMO SILENCIAR LA SE—AL DE FIN DE VIDA ÚTILEsta función de silencio puede silenciar temporalmente el “chirrido” de advertencia de fin de vida útil durante hasta 2 días. Puede silenciar el “chirrido” de advertencia de fin de vida útil pulsando el botón Test/Silence. La bocina chirriará, indicando que se activó la función silencio de fin de vida útil.

MANTENIMIENTO NORMAL Esta unidad ha sido diseñada para ser tan libre de mantenimiento como sea posible, pero existen unas cuantas cosas sencillas que usted debe hacer para mantenerla funcionando correctamente: • Pruébe al menos una vez por semana. • Limpie su detector por lo menos una vez al mes; aspire suavemente el exterior del detector utilizando el aditamento de cepillo de su aspiradora doméstica. Pruebe el detector. Nunca use agua, limpiadores o solventes, pues eso puede dañar la unidad. • Reubique la unidad si ésta emite falsas alarmas con frecuencia. Vea los detalles en “Dónde no instalar este detector”. • Cuando la batería de respaldo se debilite, el detector emitirá un “chirrido” cada minuto (la advertencia de batería baja). Usted deberá reemplazar inmediatamente la batería para seguir disfrutando de protección continua. Este detector debe tener alimentación de CA o carga de batería para operar. Si se interrumpe el suministro eléctrico y no hay batería o ésta se encuentra descargada, el detector no podrá funcionar. NO atomice sustancias químicas de limpieza ni insecticidas directamente encima o cerca del detector. NO pinte el detector. Hacerlo así puede dañarlo permanentemente. ELECCIÓN DE UNA BATERÍA DE REEMPLAZO: Su detector requiere una batería estándar de 9 voltios. Las siguientes baterías son aceptables como reemplazo: Duracell No. MN1604, (Ultra) No. MX1604; Eveready (Energizer) No. 522. Estas baterías pueden conseguirse en muchas tiendas minoristas de su localidad. • Siempre utilice las baterías exactas especificadas por este Manual de Usuario. NO use baterías recargables. Antes de instalar las baterías limpie los contactos de las baterías y también los del aparato. Instale baterías correctamente en cuanto a la polaridad (+ y -). • Por favor, desechar o reciclar adecuadamente las baterías usadas, siguiendo todas las regulaciones locales. Consulte con su autoridad local de manejo de desechos o con una organización de reciclaje para encontrar un centro de reciclaje de productos electrónicos en su área. NO DESECHE LAS BATERÍAS EN EL FUEGO. LAS BATERÍAS PUEDEN EXPLOTAR O DERRAMARSE. Mantenga las baterías fuera del alcance de los niños. En el caso de que una batería sea ingerida, contacte inmediatamente a su centro de toxicología, su médico, o a la línea de emergencia Nacional de Ingestión de Baterías al 202-625-3333 ya que pueden ocurrir daños graves. La vida útil real de la batería depende del detector y del ambiente en que éste sea instalado. Todas las baterías antes especificadas son reemplazos aceptables para esta unidad. Independientemente de la vida útil indicada por el fabricante, usted DEBE reemplazar la batería en cuanto la unidad empiece a emitir “chirridos” (la advertencia de batería baja). QUÉ NECESITA SABER SOBRE EL CO ¿QUÉ ES EL CO?El monóxido de carbono (CO) es un gas invisible, inodoro e insípido que se genera cuando los combustibles fósiles no se queman por completo o están expuestos al calor (generalmente fuego). Por lo común, los aparatos eléctricos no generan CO. Tales combustibles son: Madera, carbón mineral, carbón vegetal, aceite, gas natural, gasolina, querosene y propano. Los equipos domésticos son fuentes comunes de CO. Si no se les da mantenimiento adecuado, están mal ventilados o fallan, las concentraciones de CO pueden aumentar rápidamente. El CO es un verdadero peligro ahora que las casas son más eficientes en cuanto a la conservación de la energía. Las viviendas “hermetizadas” con mayor aislamiento, ventanas selladas y otros tratamiento de impermeabilización pueden “atrapar” el CO en su interior. SÍNTOMAS DE ENVENENAMIENTO CON COEstos síntomas se relacionan con el ENVENENAMIENTO CON CO y deben ser explicados a TODOS los ocupantes de la casa. Exposición leve: Ligero dolor de cabeza, náusea, vómito, fatiga (síntomas “parecidos al catarro”). Exposición media: Dolor de cabeza punzante, somnolencia, confusión, ritmo cardíaco acelerado. Exposición extrema: Convulsiones, pérdida del conocimiento, insuficiencia cardíaca y pulmonar. La exposición al monóxido de carbono puede ocasionar daños cerebrales y la muerte. Algunos individuos son más sensibles al CO que otros. Personas que presentan problemas cardíacos o respiratorios, infantes, fetos, madres embarazadas, o adultos mayores que pueden verse afectados más rápida y gravemente por el CO. Miembros de estos grupos sensibles deberán consultar con sus médicos para obtener consejos sobre precauciones adicionales que deberán tomar. CÓMO UBICAR LA FUENTE DE CO TRAS LA ALARMAEl monóxido de carbono es un gas inodoro e invisible, lo que dificulta a menudo la ubicación de su origen después de una alarma. Estos son unos cuantos de los factores que complican la identificación de las fuentes de CO: • Casa bien ventilada antes de que llegue el investigador. • Problemas ocasionados por “corrientes de retroceso”. • Problemas de CO momentáneos debido a circunstancias especiales. Puesto que el CO puede haberse disipado para cuando el investigador arribe, a veces es difícil ubicar su origen. BRK Brands, Inc. no estará obligada, en modo alguno, a cubrir los gastos de cualquier investigación o solicitud de servicio motivadas por monóxido de carbono. 3.875 inches3.875 inches Plantilla Guía de Montaje(98mm) (3 7/8 pulg.) POSIBLES FUENTES DE CO EN EL HOGAR Equipos de combustión domésticos, como: calentadores portátiles, chimeneas de gas o madera, estufas o parrillas de gas, secadoras de gas. Ventilación obstruida o insuficiente: tubo de ventilación de un calentador de agua corroído o desconectado, fugas en el conducto o tiro de una chimenea, fisuras en un radiador de calor, tiro de chimenea obstruido o tapado. Uso incorrecto de equipos o aparatos: utilizar una parrilla de carbón o encender un vehículo en un lugar encerrado (como un garaje o un vestíbulo cerrado). Problemas momentáneos de CO: los problemas de CO “transitorios” o intermitentes pueden deberse a condiciones externas u otras circunstancias especiales. Las siguientes condiciones pueden ocasionar problemas de CO transitorios: 1. Desborde excesivo o ventilación inversa de los equipos de combustión debido a condiciones externas como: • Dirección y/o velocidad del viento, incluyendo ventarrones fuertes e irregulares. Aire denso en los conductos de ventilación (aire frío y/o húmedo con periodos prolongados entre ciclos). • Un diferencial de presión negativo como consecuencia del uso de ventiladores de escape. • Varios equipos que funcionan al mismo tiempo compiten por una fuente limitada de aire fresco. • Las conexiones de los conductos de ventilación de secadoras, calderas o calentadores de agua se aflojaron debido a vibraciones. • Obstrucciones o configuraciones tortuosas de los conductos de ventilación, lo que acrecienta las situaciones anteriores. 2. Operación prolongada de equipos de combustión no ventilados (estufas, hornos o chimeneas). 3. Inversiones térmicas que pueden atrapar los gases de escape cerca del suelo. 4. Vehículo en marcha al ralentí en un garaje abierto o cerrado, o cerca de la casa. Estas condiciones son peligrosas porque pueden atrapar los gases de combustión dentro de su casa. Puesto que tales situaciones son impredecibles, también es difícil reproducirlas durante una investigación de CO. ¿CÓMO PUEDO PROTEGER A MI FAMILIA DEL ENVENENAMIENTO CON CO? Un detector de gas y CO es un medio de protección excelente. Éste mide el aire y emite una fuerte alarma antes de que las concentraciones de monóxido de carbono pongan en peligro a los adultos promedio saludables. El detector de gas y CO no sustituye el mantenimiento adecuado de los equipos domésticos de combustión. Para prevenir problemas de CO y disminuir el riesgo de envenenamiento con CO: • Limpie anualmente las chimeneas y los conductos de tiro. Manténgalos libres de basura, hojas y nidos de aves para permitir el libre flujo del aire. Además, haga que un profesional los revise en busca de indicios de oxidación y corrosión, fisuras o separaciones. Estas condiciones pueden impedir el flujo adecuado del aire y provocar corrientes de retroceso. Jamás “tape” o cubra una chimenea de modo que se interrumpa el libre flujo del aire. • Verifique y mantenga anualmente todos los equipos de combustión. Muchas compañías locales de gas y aire acondicionado ofrecen inspecciones de tales equipos mediante el pago de un honorario nominal. • Inspeccione visualmente con regularidad todos sus equipos de combustión. Revíselos en busca de oxidación excesiva y formación de escamas. Revise también la llama del quemador y las llamas piloto. La llama debe ser azul. Una llama amarilla significa que el combustible no está quemándose por completo y que puede estar generándose CO. Mantenga cerrada la compuerta del soplador de las calderas. De ser posible, use ventiladores o extractores en todos los equipos de combustión. Cerciórese de que los equipos de combustión expulsen sus gases de escape al exterior. No encienda parrillas de carbón en el interior de la casa, en un garaje o en un vestíbulo cerrado. • Asegúrese de que no haya corrientes de retroceso en las fuentes de CO. Cerciórese de que la capucha de tiro de las calderas no tenga corrientes de retroceso cuando la caldera esté encendida. Busque fisuras en los radiadores de calor de las calderas. • Revise la casa o el garaje por el otro lado del muro compartido. • Mantenga las ventanas y puertas ligeramente abiertas. Si sospecha que se está generando CO dentro de su casa, abra una ventana o una puerta. Abrir ventanas y puertas puede disminuir considerablemente las concentraciones de CO. Además, conozca en detalle toda la información que le proporcionamos. Lea por completo este manual y cerciórese de haber comprendido lo que debe hacer en caso de que su detector de gas y CO suene. INFORMACIÓN NORMATIVA PARA DETECTORES DE GAS EXPLOSIVO Y CO INFORMACIÓN NORMATIVA PARA DETECTORES DE CO NORMA DE SEGURIDAD UL2034 ¿QUÉ CONCENTRACIONES DE CO PROVOCAN UNA ALARMA? Según la Norma UL2034 de Underwriters Laboratories, Inc., los detectores de CO de tipo residencial deben sonar al estar expuestos a las concentraciones de CO y los tiempos de exposición siguientes. Estos valores se miden en partes por millón (ppm) de CO respecto al tiempo (en minutos). Puntos de alarma exigidos por la UL2034*: • Si el detector está expuesto a 400 ppm de CO, DEBE SONAR EN 4 A 15 MINUTOS. • Si el detector está expuesto a 150 ppm de CO, DEBE SONAR EN 10 A 50 MINUTOS. • Si el detector está expuesto a 70 ppm de CO, DEBE SONAR EN 60 A 240 MINUTOS. * Aproximadamente 10% de exposición a COHb, con una humedad relativa (HR) de 10% a 95%. La unidad está diseñada para no sonar cuando está expuesta a concentraciones constantes de 30 ppm durante 30 días. Los detectores de CO están diseñados para sonar antes de que exista un riesgo inmediato para la vida. Puesto que usted no puede ver ni oler el CO, jamás suponga que no está presente. • Una exposición a 100 ppm de CO durante 20 minutos puede no afectar a los adultos promedio saludables, pero después de 4 horas, la misma concentración puede provocar dolores de cabeza. • Una exposición a 400 ppm de CO le provoca dolor de cabeza a los adultos promedio saludables en 35 minutos y puede ocasionarles la muerte en 2 horas. Este detector de CO mide la exposición al CO con el tiempo. Hace sonar la alarma si las concentraciones de CO se vuelven extremadamente altas en poco tiempo o si alcanzan un cierto mínimo en un tiempo prolongado. En general, el detector de gas y CO empieza a sonar la alarma antes de que se presenten síntomas en el promedio de los adultos saludables.¿Por qué es importante esto? Porque usted necesita ser advertida(o) de un posible problema de CO mientras aún puede reaccionar a tiempo. En muchos casos reportados de exposición al CO, las víctimas están concientes de no sentirse bien, pero se desorientan y ya no pueden reaccionar suficientemente bien para salir del edificio o solicitar ayuda. Además, los niños chicos y las mascotas son los primeros en ser afectados. El adulto promedio saludable pudiera no sentir ninguno de los síntomas al sonar la alarma de CO. Sin embargo, el CO puede afectar más rápida y gravemente a las personas con problemas cardíacos o respiratorios, los lactantes, los bebés por nacer, las madres embarazadas o los ancianos. Si usted percibiera síntomas de envenenamiento por CO, por leves que sean, ¡consulte de inmediato a su médico! Estándares: Underwriters Laboratories, Inc. UL2034, Detectores de monóxido de carbono con una o múltiples estaciones. Según la norma UL2034 de Underwriters Laboratories, Inc., Sección 1-1.2: “Los detectores de monóxido de carbono cubiertos por estos requisitos, deberán responder a la presencia de monóxido de carbono proveniente de fuentes como motores de combustión interna, operación anormal de equipos alimentados por combustibles y chimeneas, sin limitarse a ellas. Los detectores de CO tienen por objeto alertarle en cuanto a la presencia de concentraciones de monóxido de carbono inferiores a las que puedan provocar pérdida de la capacidad de reaccionar ante el peligro de exposición al monóxido de carbono”. Este detector de CO evalúa el aire que llega a él y está diseñado para sonar antes de que las concentraciones de CO pongan en riesgo la vida. Esto le da a usted un tiempo precioso para salir de la casa y corregir el problema. Esto sólo es posible cuando los detectores se ubican, instalan y mantienen como se explica en este manual. Detección del gas dentro de los límites normales de temperatura y humedad: En general, el detector de CO no está diseñado para detectar concentraciones de CO por debajo de 30 ppm. Ha sido probado por UL como resistente a la falsa alarma por metano (500 ppm), butano (300 ppm), heptano (500 ppm), acetato de etilo (200 ppm), alcohol de isopropilo (200 ppm), y dióxido de carbono (5000 ppm). Los valores miden las concentraciones de gas y vapor en partes por millon. Alarma auditiva: 85 dB como mínimo a 3 metros (10 pies) de distancia. INFORMACIÓN NORMATIVA PARA DETECTORES DE GAS EXPLOSIVOEstándares: Underwriters Laboratories Inc. UL1484. En conformidad con Underwriters Laboratories Inc. UL1484, esta unidad cumple con el tiempo de respuesta de alarma para gas de la siguiente forma: Esta unidad sonará antes de que el 25% del LIE de gas natural o propano sea detectado. En todos los casos, la unidad le dará prioridad a la detección de gas por sobre la de monóxido de carbono. Si el dispositivo está detectando CO, y luego detecta una cantidad de gas como para dar la alarma, el dispositivo dejará de dar la alarma de CO y comenzará a dar la de gas. LIMITACIONES GENERALES DE LOS DETECTORES DE GAS EXPLOSIVO Y CO Este detector de gas y CO fue diseñado exclusivamente para uso residencial. No fue pensado para aplicaciones industriales en las que deban cumplirse los requisitos que señala la Occupational Safety and Health Administration (OSHA) para los detectores de monóxido de carbono. Este dispositivo no fue diseñado para alertar a las personas con problemas auditivos. No todas las personas se pueden despertar con los detectores de gas/CO. Si los niños u otras personas no se despiertan rápidamente ante el sonido del detector de gas/ CO o si hay bebés o miembros de la familia con limitaciones de movilidad, asegúrese de que se les asigne alguien para que les ayude en el caso de una emergencia. Este detector de gas y CO no detectará el gas o el CO que no llegue hasta los sensores. Sólo detecta el gas o el CO que llega al sensor. Puede haber gas o CO en otras áreas. Las puertas u otras obstrucciones pueden afectar la rapidez con que el CO o el gas llega a los sensores. Las alarmas de gas y CO pueden no ser escuchadas. El volumen de la sirena de alarma cumple o rebasa las normas actuales de los UL, es decir, 85 dB a 3 metros (10 pies) de distancia.

Carbon Monoxide and Explosive Gas Alarm User’s Guide Model: KN-COEG-3 (900-0113) • 120V AC • 9V Battery Backup • Peak Level Memory KN-COEG-3 with Digital Display SINGLE STATION CARBON MONOXIDEALARM ALSO SUITABLE FOR USE AS ARESIDENTIAL GAS DETECTOR 2509-7214-01(820-1557B ):_ 2010.2.1 9:27 AM Page 1 Carbon Monoxide Alarm Procedure 1)Operate the Test/Reset button; 2)Call your emergency services (Fire Department or 911); 3)Immediately move to fresh air - outdoors or by an open door/window. Do a head count to check that all persons are accounted for. Do not reenter the premises nor move away from the open door/window until the emergency services responders have arrived, the premises have been aired out, and your alarm remains in its normal condition. 4)After following steps 1-3, if the alarm reactivates within a 24 hour period, repeat steps 1-3 and call a qualified appliance technician to investigate sources of CO from fuel burning equipment and appliances, and to inspect for proper operation of equipment. If problems are identified during this inspection, have the equip- ment serviced immediately. Note any combustion equipment not inspected by the technician and consult the manufacturer’s instruc- tions, or contact the manufacturer’s directly for more information about CO safety and the equipment. Make sure that motor vehicles are not, or have not been, operating in a garage attached or adja- cent to the residence. Never restart the source of a CO problem until it has been corrected. Never ignore the sound of the alarm! If the alarm is sounding, pressing the test/reset button will terminate the alarm. If the CO condition that caused the alert in the first place continues, the alarm will reactivate. If the unit alarms again within six minutes, it is sensing high levels of CO which can quickly become a dangerous situation. WARNING:Activation of the CO Alarm indicates the presence of Carbon Monoxide (CO) which can kill you. PHONE NUMBER: PHONE NUMBER: What to do When the Alarm Sounds!2509-7214-01(820-1557B ):_ 2010.2.1 9:27 AM Page 2 Gas Alarm Procedure When the unit senses either natural gas or propane, the display will show “GAS” and emit a loud alarm pattern. The alarm pattern for gas is a 1/2 second beep followed by a 1/2 second of silence then repeat- ing. Know how to respond to a CO or gas emergency. If the unit alarms for gas: 1)Evacuate the premises; 2)Do not activate any electrical switch or telephone; 3)Contact your fire department. NOTE: If Gas is present the unit will continue to alarm even if the “Test/Reset” button is pressed. Unit will stop alarming if gas is removed. WARNING:Activation of the Gas Alarm indicates the presence of an explosive gas which can cause an explosion and/or fire. PHONE NUMBER: What to do When the Alarm Sounds!2509-7214-01(820-1557B ):_ 2010.2.1 9:27 AM Page 3 WelcomeNote: Many times throughout this User’s Guide, we will refer to Carbon Monoxide as “CO”. The words “Gas” or “Explosive Gas” will refer to Natural Gas or Propane. This Kidde carbon monoxide (CO) and gas alarm is an important part of your family’s home safety plan. This alarm has been designed and tested to detect CO and gas buildup in a residential environment. Your alarm is for use specifically in the home. As an owner of a CO and gas alarm, there are some basic facts you should know about for your protection. Many people think that CO and gas alarms operate like smoke alarms. Like smoke alarms, CO and gas alarms monitor the air in your home and sound a loud alarm to warn you of trouble. The way you respond to a CO and gas alarm is quite different than a smoke alarm. That’s because a house fire and a CO or gas problem are distinctly different situations. If your smoke alarm were to alarm, you would quickly be able to judge the level of danger you were in with your senses. You can see and smell the smoke, feel the heat, see, and possibly hear the fire burning. You can also readily see if your smoke alarm is alarming in a non-emergency situ- ation. Because your sense of sight, smell, hearing and touch give you information, you can almost instantly judge what action to take if you hear your smoke alarm. CO is an invisible, odorless, tasteless and non-irritating gas – completely undetectable to your senses. That’s why it is important to your safety that you have a CO alarm. Note: Refer to Section 1 for information about natural gas and propane. Important Warning Statements IMPORTANT: This carbon monoxide and gas alarm is designed to detect carbon monoxide from ANY source of combustion. This alarm will also detect the presence of natural gas or propane. It is NOT designed to detect smoke or fire. WARNING: Carbon monoxide alarms are not smoke alarms. This carbon monoxide alarm is not a substitute for installing and maintaining an appropriate number of smoke alarms in your home. This carbon monoxide and gas alarm will not sense smoke or fire, even though carbon monoxide can be generated by fire. For this reason you must install smoke alarms to provide early warning of fire and to protect you and your family from fire and its related hazards. 2509-7214-01(820-1557B ):_ 2010.2.1 9:27 AM Page 4 Important Warning StatementsCAUTION: This alarm will only indicate the presence of carbon monoxide, natural gas or propane at the sensor. Carbon monox- ide, natural gas or propane may be present in other areas. WARNING: This product is intended for use in ordinary indoor locations of family living units. It is not designed to measure com- pliance with Occupational Safety and Health Administration (OSHA), commercial or industrial standards. It is not suitable for installation in hazardous locations as defined in the National Electric Code. The installation of this device should not be used as a substitute for proper installation, use and maintenance of fuel burning appliances, including appropriate ventilation and exhaust sys- tems. It does not prevent CO or gas from occurring, nor can it solve and existing CO or gas problem. WARNING: This device is designed to protect individuals from acute effects of carbon monoxide exposure. It may not fully safe- guard individuals with specific medical conditions. If in doubt, consult a medical practitioner. Individuals with medical problems may consider using warning devices which provide audible and visual signals for carbon monoxide concentrations under 30 PPM. This carbon monoxide and gas alarm requires a continuous supply of electrical power – it will not work without power. Models without battery backup will not operate during power failure. The alarm will detect carbon monoxide primarily and explosive gas secondarily. CO events will take presidence over explosive gas events. This alarm has not been investigated for carbon monoxide detec- tion below 70 PPM.

CO inhibits the blood’s capacity to carry oxygen. Periodically review this alarm manual and discuss your CO alarm emer- gency procedure with all the members of your family. Never ignore a CO alarm. A true alarm is an indication of potentially dangerous levels of CO. CO alarms are designed to alert you to the presence of CO before an emergency – before most people would experience symptoms of CO poisoning, giving you time to resolve the problem calmly. Determine if anyone in the household is experiencing symptoms of CO poisoning. Many cases of reported CO poisoning indicate that while victims are aware they are not well, they become so disoriented they are unable to save themselves by either exiting the building or calling for assistance. Also, young children and household pets may be the first affected. You should take extra precautions to protect high-risk persons from CO exposure because they may experience ill effects from CO at levels that would not ordinarily affect a healthy adult. Symptoms of CO Poisoning The following common symptoms are related to CO poisoning and should be discussed with ALL members of the household. Mild Exposure: Slight headache, nausea, vomiting, fatigue (often described as “flu-like” symptoms). Medium Exposure: Severe throbbing headache, drowsiness, confusion, fast heart rate. Extreme Exposure: Unconsciousness, convulsions, cardio-respiratory failure, death. If you experience even mild symptoms of CO poisoning, consult your doctor immediately! Carbon Monoxide PPM Levels Model KN-COEG-3 is equipped with a digital display that shows levels of CO (displayed in PPM – parts per million). Learn the difference between dangerous, high, mid and low levels. Dangerous Levels: When someone is experiencing symptoms of CO poisoning and CO readings are generally above 100 PPM. Anytime someone is experiencing the symptoms of CO poisoning this should be treated as an emergency. 1. Information About Carbon Monoxideand Explosive Gas2509-7214-01(820-1557B ):_ 2010.2.1 9:27 AM Page 6 See “What to do When the Alarm Sounds” (inside front cover). High Levels: Generally above 100 PPM, with no one experiencing symptoms. This should be treated as an urgent situation. See “What to do When the Alarm Sounds” (inside front cover). Mid Levels: Generally between 50 PPM to 100 PPM. This should be cause for concern and should not be ignored or dismissed. See “What to do When the Alarm Sounds” (inside front cover). Low Levels: Generally below 50 PPM. Kidde recommends you take action to eliminate the source of CO. See “What to do When the Alarm Sounds” (inside front cover). Possible Sources of Carbon Monoxide Inside your home, appliances used for heating and cooking are the most likely sources of CO. Vehicles running in attached garages can also produce dangerous levels of CO. CO can be produced when burning any fossil fuel, such as gasoline, propane, natural gas, oil and wood. It can be produced by any fuel- burning appliance that is malfunctioning, improperly installed, or not ventilated correctly, such as: • Automobiles, furnaces, gas ranges/stoves, gas clothes dryers, water heaters, portable fuel burning space heaters and generators, fireplaces, wood-burning stoves and certain swimming pool heaters. • Blocked chimneys or flues, back drafts and changes in air pressure, corroded or disconnected vent pipes, loose or cracked furnace exchangers. • Vehicles and other combustion engines running in an open or closed garage, attached or near a home. • Burning charcoal or fuel in grills and hibachis in an enclosed area. Conditions That Can Produce Carbon Monoxide The following conditions can result in transient CO situations: • Excessive spillage or reverse venting of fuel-burning appliances caused by outdoor ambient conditions, such as, wind direction and/or veloci- ty, including high gusts of wind, heavy air in the vent pipes (cold/humid air with extended periods between cycles). 1. Information About Carbon Monoxideand Explosive Gas2509-7214-01(820-1557B ):_ 2010.2.1 9:27 AM Page 7 • Negative pressure resulting from the use of exhaust fans. • Simultaneous operation of several fuel-burning appliances competing for limited internal air. • Vent pipe connections vibrating loose from clothes dryers, furnaces, or water heaters. • Obstructions in, or unconventional, vent pipe designs which can amplify the above situations. • Extended operation of unvented fuel-burning devices (range, oven, fireplace, etc.). • Temperature inversions which can trap exhaust gases near the ground. • Vehicle idling in an open or closed garage, or near a home. To be safe, know the possible sources of CO in your home. Keep fuel- burning appliances and their chimneys and vents in good working condi- tion. Learn the early symptoms of exposure, and if you suspect CO poi- soning, move outside to fresh air and get emergency help. Your first line of defense is an annual inspection and regular maintenance of your appliances. Contact a licensed contractor or call your local utility compa- ny for assistance. Information About Carbon Monoxide Alarms – What They Can and Cannot Do: CO alarms provide early warning of the presence of CO, usually before a healthy adult would experience symptoms. This early warning is possible, however, only if your CO alarm is located, installed and maintained as described in this guide. Because carbon monoxide is a cumulative poison, long-term exposures to low levels may cause symptoms, as well as short-term exposures to high levels. This Kidde unit has a time-weighted alarm – the higher the level of CO present, the sooner the alarm will be triggered. This CO alarm can only warn you of the presence of CO. It does not prevent CO from occurring, nor can it solve an existing CO problem. If your unit has alarmed and you’ve provided ventilation by leaving your windows and doors open, the CO buildup may have dissipated by the time help responds. Although your problem may appear to be temporarily solved, it’s crucial that the source of the CO is determined and that the appropriate repairs are made. 1. Information About Carbon Monoxideand Explosive Gas2509-7214-01(820-1557B ):_ 2010.2.1 9:27 AM Page 8 This CO alarm is designed to act as a monitor; it is not designed for use as a short-term testing device to perform a quick check for the presence of CO. CO alarms have limitations. Like any other electronic device, CO alarms are not fool-proof. CO alarms have a limited operational life. You must test your CO alarm weekly, because it could fail to operate at any time. If your CO alarm fails to test properly, or if its self-diagnostic test reveals a malfunction, immediately have the unit replaced. This alarm will not monitor CO levels while in an error condition. CO alarms can only sense CO that reaches the unit’s sensor. It’s possible that CO may be present in other areas without reaching the alarm. The rate and ability that which CO reaches the alarm may be affected by: • Doors or other obstructions. • Fresh air from a vent, an open window or other source. • CO being present on one level of the home and not reach a CO alarm installed on a different level. (For example, CO in the basement may not reach an alarm on the second level, near the bedrooms). For these reasons, we recommend you provide complete coverage by placing a CO alarm on every level of the home. Please carefully read all information on properly installing this CO alarm. CO alarms should not be used to detect the presence of natural gas (methane), propane, butane, or other combustible fuels. Instruct children never to touch, unplug or otherwise interfere with the alarm. Warn children of the dangers of CO poisoning. General Information About Explosive Gas: Natural Gas is typically supplied through a main utility line connected to your home. If you do not live in a rural area you are likely to be a user of natural gas. Natural gas is much lighter than air and will rise rapidly. If you are a user of natural gas, mount your CO and Gas alarm 12 inches away from the ceiling to ensure the earliest opportunity to detect a leak. Propane is typically supplied to homes via delivery truck in liquid form and stored near the home in propane tanks. Propane and LP-gas (lique- fied petroleum) are often used synonymously. Propane is much heavier than air and will collect at lower levels. If you are a user of propane, mount your CO and Gas alarm near the floor to ensure the earliest opportunity to detect a leak. 1.

For safety rea- sons, an odorant (Mercaptan) is added so that any leak can be detected by smell. The common detection threshold for smelling the gases is around 20% of the lower explosion limit (LEL). This can vary greatly depending on the individuals’ sense of smell and how long they have been exposed to either gas. The LEL of each of these gases defines the bottom range of flammability for the gas. Your CO and Gas alarm is cali- brated to alarm before 25% of the LEL of either gas detected. Therefore, it is possible that you may smell gas before the alarm activates. 1. Information About Carbon Monoxideand Explosive Gas2509-7214-01(820-1557B ):_ 2010.2.1 9:27 AM Page 10 2. Product Features and SpecificationsIMPORTANT: Seven (7) years after the initial power up, this alarm will “beep” two times every 30 seconds to indicate that it is time to replace the alarm. Replace the alarm immediately! It will not detect CO in this condition. To help identify the date to replace the alarm, a label has been affixed to the side of the alarm. Write the “replace by” date (seven years from power up) in a permanent marker on this label.

CO Alarm Response Times: 70 PPM = 60-240 min., 150 PPM = 10-50 min., 400 PPM = 4-15 min. Gas Alarm Response Times: Before 25% of low explosion limit (LEL) for natural gas or propane is detected. 2509-7214-01(820-1557B ):_ 2010.2.1 9:27 AM Page 11 Recommended Installation Locations CO and Gas alarms should be mounted in or near bedrooms and living areas. It is recommended that you install a CO and Gas alarm on each level of your home. When choosing your installation locations, make sure you can hear the alarm from all sleeping areas. If you install only one CO and Gas alarm in your home, install it near bed- rooms, not in the basement or furnace room. • When wall mounting, place out of reach of children. Under no cir- cumstances should children be allowed to handle the CO and Gas alarm. • Mounting the CO and Gas alarm should depend on the type of explo- sive gas you intend to detect: – If you are a user of natural gas, mount your CO and Gas alarm high on the wall (no closer than six inches from the ceiling) to ensure the earliest opportunity to detect a natural gas leak. – If you are a user of propane, mount your CO and Gas alarm near the floor to ensure the earliest opportunity to detect a propane leak. Locations To Avoid IMPORTANT:Improper location can affect the sensitive electronic com- ponents in this alarm. To avoid causing damage to the unit, to provide optimum performance, and to prevent unnecessary nuisance alarms: • Do not install in kitchens, garages or furnace rooms that may expose the sensor to substances that could damage or contaminate it. • Do not install in areas where the temperature is colder than 40°F (4.4°C) or hotter than 100°F (37.8°C) such as crawl spaces, attics, porches and garages. • Do not install within 5 ft. of heating or cooking appliances. (Kidde recommends 15 ft. to prevent nuisance alarms). • Do not install near vents, flues, chimneys or any forced/unforced air ventilation openings. • Do not install near ceiling fans, doors, windows or areas directly exposed to the weather. 3. Installation Locations Recommended Locations 2509-7214-01(820-1557B ):_ 2010.2.1 9:27 AM Page 12 How to Install Your Alarm Your Kidde CO and Gas alarm with its removable adapter allows you to install the alarm as a wall mounted unit, a direct plug unit, or as a table top unit. Direct Plug Alarm In its “as shipped” configuration, all you need to do is install the 9V backup battery and your Kidde CO and Gas alarm is ready to be plugged directly into a wall socket. To install: 1. Choose a standard 120V unswitched outlet to plug the alarm into. 2. Pull the slide support out approximately 1/4” until the slide snaps into place. This will help support unit in the wall outlet. 3. Plug the alarm into the outlet. If the outlet is mounted horizontally (sideways): If you are going to use your alarm as a direct plug and you are going to plug in to an outlet that is mounted horizontally (sideways), you will need to rotate the adapter 90˚. To rotate the adapter: 1. Remove back door by sliding it down and out. 4. Installation Instructions Back of alarm when used as direct plug unit Back of alarm when used as direct plug unit • Do not install in dead air spaces, such as peaks of vaulted ceilings or gabled roofs, where CO or gas may not reach the sensor in time to provide early warning. • Do not install this unit near deep-cell large batteries. Large batteries have emissions that can cause the alarm to perform at less than opti- mum performance. • Do not obstruct the vents located on the alarm. Do not place the alarm where drapes, furniture or other objects block the flow of air to the vents. • Do not install on a switched or dimmer-controlled outlet. 3. Installation Locations2509-7214-01(820-1557B ):_ 2010.2.1 9:27 AM Page 13 2. Spread adapter thumb releases out and carefully turn alarm over. This will allow adapter to slide out. 3. Lift the adapter completely out of the alarm and rotate the adapter 90˚ to the right (clockwise). Snap it firmly back into place. 4. Carefully replace the back door. Insure the “latches” on all four corners of the door are lined up, then press the door securely into place. 5. Plug the alarm into an unswitched wall socket. Wall Mounted Alarm Installation tips for power cord models: The power cord option provides more flexi- bility in mounting locations and allows the alarm to be easily installed at eye level. For a wall-mounted unit, you will need to pull out the removable adapter and power cord. To install: 1. Follow steps 1 through 4 in the previous section under “To Rotate the Adapter.” 2. With the adapter removed, pull the power cord out of the cord recess, remove the twist tie, and extend the power cord. 3. With the power cord extended, press the last few inches of the power cord back into the cord recess. Gently pull the cord at the bottom of the cord recess until the cord becomes taught and lays flat in cord recess. 4. Carefully replace the back door. Insure the “latches” on all four cor- ners of the door are lined up, then press the door securely into place. 5. Mark the location for the two mounting holes on the wall spaced ver- tically 2 5/8" apart. 6. If you are mounting the alarm in plaster board or drywall, drill a 3/16" hole into the wall and insert the plastic anchors provided. Install the 4.

Alarm Characteristics Carbon Monoxide Alarm Indicator This CO and Gas alarm is designed to act as a monitor. It is not designed for use as a short term testing device to perform a quick check for the presence of CO or gas. When the alarm senses a dangerous level of CO, the unit will emit a loud alarm pattern. The alarm pattern is 4 quick beeps followed by 5 seconds of silence. This cycle repeats as long as a dangerous CO condi- tions exist. The digital display will indicate the CO concentration in parts per million (PPM). When the unit senses either natural gas or propane, the display will show “GAS” and emit a loud alarm pattern. The alarm pattern for gas is 1/2 second beep followed by a 1/2 second of silence then repeating. In all cases, the unit will detect CO as a priority over gas. If the unit is detecting gas, then detects an amount of CO to cause an alarm, the unit will stop alarming for gas and alarm for CO. two screws provided into the wall or wall anchors until the screw head is approximately 1/8" from the wall. 7. Hook the unit over the screw head and into the key- hole in back of the unit. 8. Plug the adapter into an unswitched wall socket. Table Top Alarm You can use your CO and Gas alarm as a table top unit. Follow steps 1 thru 4 above. Instead of mounting the unit to a wall, pull out the slide support and place in a location that is easily visible. Be sure the alarm is no more than three feet from the floor. Important Labels Provided Two labels have been provided that have important information on what to do in case of an alarm.

Alarm CharacteristicsWARNING:When powered by battery backup only; after four minutes, this alarm pattern occurs only every 60 seconds, until the alarm is reset or the CO is eliminated. • The digital display will show a the PPM of CO or show “GAS” only if it senses carbon monoxide or gas while in backup mode. • If gas is detected while on battery backup, the unit will display “GAS” and alarm in 1/2 second beeps. For the first four minutes after the unit goes into battery backup operation, the explosive gas sensor will operate as if on AC power. However, after four minutes, to extend battery life, the unit will go into battery conserve mode and will only sample for explosive gas once every eight minutes. Explosive gas could be present during this 8-minute peri- od without the unit going into alarm. If the alarm is on battery backup for an extended period of time, replace the battery to ensure maximum protection is provided. The battery will last only a couple hours in a gas alarm condition. WARNING:If at any time you test the alarm and it does not perform as described, have it replaced immediately. Whenever the CO and Gas alarm is first powered up, it will sound briefly to let you know it is receiving power and that the alarm is functioning. You will see three eights on the digital display, indicating the alarm is in the start-up mode. The three eights will remain for approximately 20 seconds. You will see a blinking red dot to the lower right of the digital display. The blinking dot shows that the alarm is operating. Within 20 seconds, your CO and Gas alarm will start monitoring for CO. Within 2 minutes your alarm will start monitoring for gas. This alarm will display a 0 if CO concentrations between 0 and 30 PPM have been detected within the last 15 seconds. The alarm has begun monitoring the air for CO and gas and will continue to as long as it receives power. When the alarm is unplugged or loses power and a good 9V bat- tery is installed: The alarm will automatically switch to its battery back- up mode and you will notice the following: • After 4 minutes the digital display will show a blinking dot only – this helps conserve the battery’s power. 6. Model KN-COEG-3 Operating Characteristics 2509-7214-01(820-1557B ):_ 2010.2.1 9:27 AM Page 16 If the battery is low or missing, or if the unit malfunctions, it will display other readings (and alarm differently) to alert you of specific conditions. Please familiarize yourself, and other family members, to the difference between a CO reading and and indication signifying a problem with the unit itself. NOTE: When AC power is restored, the alarm will automatically switch back to normal operating mode. The alarm will not detect CO or gas if battery is depleted. Replace bat- tery. The following table illustrates the possible digital displays, describes the audible alarm patterns, and the recommended actions to take. 6.

The Peak Level display feature will display levels between 11-999 PPM. Although the Peak Level feature will display levels below 30 PPM, these levels will not result in an alarm no matter how long the device is exposed to these levels. The Peak Level feature is helpful in identifying if you have had a CO reading since resetting the alarm. Concentrations of CO between 1 and 30 PPM can often occur in nor- mal, everyday conditions. Concentrations of CO below 30 PPM may be an indication of a transient condition that may appear today and never reappear. Some CO conditions may start out as low level leaks but could develop into CO concentrations that may become harmful. Peak Level Memory Reset Press the Peak Level button; with the button still pressed, press the Test/Reset button for two seconds and release. The number on the dis- play will turn to “0”, the memory will be cleared and the alarm will begin monitoring for CO. The Peak Level memory is also reset when the unit loses power. 6.

Due to the loudness of the alarm, we suggest that you place your fingers over the sounder opening while testing your alarm. CAUTION: Continuous exposure to the high sound level of this alarm over an extended period of time may cause hearing loss. Testing Observe the alarm weekly to make sure the red dot is blinking, indicat- ing normal operation. If the dot is not blinking, unplug the alarm for three minutes, then plug in again. This will clear the alarm for restart. If the dot does not resume blinking, your alarm may be malfunctioning. To test the alarm,press the Test/Reset button. If the alarm is operating properly, you will notice the following: • The display shows three “eights”, then shows the word “GAS” while the alarm is sounding three short “beeps”. Then, the display shows a number (usually around 200). You will then hear four quick “beeps” – followed by five seconds of silence – followed by four quick “beeps” repeating until reset stops. The unit will then show three “eights” for several seconds. It will then return to monitoring for CO and gas. Familiarize yourself and household members with the alarm pattern described above for a CO or gas event. While on AC power, in the event of a CO or gas incident, the appropriate pattern will continue to repeat as long as CO or gas is present. NOTE:Pressing the Test/Reset button tests the functions of the alarm’s internal components, circuitry and micro-computer. You do not need to press the Test/Reset button to take a CO or gas reading.CO readings or the presence of gas are automatically shown on the alarm’s digital display. If the alarm shows “0”, then no measurable amount of CO or gas has been sensed by the alarm within the past 15 seconds. Battery Replacement NOTE: This CO and Gas alarm is not battery operated.However, this alarm is equipped with 9 volt battery backup – the 9 volt battery is to supply short term back-up during a power outage. When replacing the battery, use one of the following approved brands: • Duracell MN1604 or MX1604 • Energizer 522 • Gold Peak 1604A 2509-7214-01(820-1557B ):_ 2010.2.1 9:27 AM Page 19 7. MaintenanceThese batteries can be purchased where you bought the alarm or at a local hardware store. Use of a different battery may have a detrimental effect on the alarm operation. The 9 volt battery is not rechargeable. If the 9 volt battery is missing, disconnected, or if the battery’s power is low, “Lb” will be displayed alternately with the current CO reading once every second accompanied by an audible beep every 15 seconds. If this happens, the battery must be replaced. To replace battery: Remove back door by sliding it down and out. Remove battery by unsnapping it from the battery clip. Install a new battery by connecting it to the battery clip and place into the recessed battery cavity. Reinstall the back door of the unit. IMPORTANT:Constant exposures to high or low humidity may reduce battery life. A good safety measure is to replace the battery at least once a year, or at the same time as you change your clocks for daylight saving time. After installing or changing the battery, reinstall your alarm. Test your alarm by using the Test/Reset button and check that the display is on. Maintenance Tips To keep your alarm in good working order, you must follow these steps: • Test the alarm once a week by pressing the Test/Reset button. • Vacuum the alarm cover once a month to remove accumulated dust. • Never use detergents or solvents to clean the alarm. Chemicals can permanently damage or temporarily contaminate the sensor. • Avoid spraying air fresheners, hair spray, paint or other aerosols near the alarm. • Do not paint the unit. Paint will seal the vents and interfere with proper sensor operation. 2509-7214-01(820-1557B ):_ 2010.2.1 9:27 AM Page 20 7. MaintenanceMove the CO and Gas alarm to a remote location, to prevent possible damage or contamination of the sensor, prior to performing any of the following: • Staining or stripping floors or furniture, painting or wall-papering • Using aerosols or adhesives WARNING:Reinstall the CO and Gas alarm as soon as possible to assure continuous protection. The following is a list of substances that at high levels can damage the sensor or cause temporary readings that are not CO readings: • Ethylene, ethanol, alcohol, iso-propanol, benzene, toluene, ethyl acetate, hydrogen, hydrogen sulfide and sulfur dioxide. • Also most aerosol sprays, alcohol based products, paint, thinner, sol- vent, adhesive, hair spray, after shave, perfume, auto exhaust (cold start) and some cleaning agents. 2509-7214-01(820-1557B ):_ 2010.2.1 9:27 AM Page 21 FIVE YEAR LIMITED WARRANTYWarranty Coverage:The manufacturer warrants to the original consumer purchaser, that this product (except battery) will be free of defects in material and workmanship for a period of five (5) years from date of purchase.

Approximate Area of New Home Construction 13MAR18   Appendix E Dwyer 2-5005 Specification Sheet Differential Pressure GagesPRESSUREDWYER INSTRUMENTS, INC.| www.dwyer-inst.com10 Combining clean design, small size, and low cost with enough accuracy for all, but the most demanding applications our Minihelic®II gage offers the latest in design features for a dial type differential pressure gage. It is our most compact gage, but is easy to read and can safely operate at total pressures up to 30 psig. The Minihelic®II is designed for panel mounting in a single 2-5/8˝ diameter hole. Standard pressure connections are barbed fittings for 3/16˝ ID tubing; optional 1/8˝ male NPT connections are also available. Over-pressure protection is built into the Minihelic II®gage by means of a blow-out membrane molded in conjunction with the diaphragm. Accidental over-ranging up to the rated total pressure will not damage the gage. With removable lens and rear housing, the gage may be easily serviced at minimum cost. With the housing molded from mineral and glass filled nylon and the lens molded from acrylic, the gage will withstand rough use and exposure as well as high total pressure. The 5% accuracy and low cost of the Minihelic®II gage make it well-suited for a wide variety of OEM and user applications. OEM applications include cabinet air purging, medical respiratory therapy equipment, air samplers, laminar flow hoods, and electronic air cooling systems. As an air filter gage, the Minihelic®II gage finds many end use applications on large stationary engines, compressors, ventilators, and air handling units. The Minihelic®II gage is suitable for many of the same applications as the Magnehelic®gage where the greater accuracy, sensitivity, and higher and lower differential pressure ranges of the Magnehelic®gage are not required.

Wetted Materials: Consult factory. Housing: Glass filled nylon; acrylic lens. Accuracy: ±5% of FS at 70°F (21.1°C). Pressure Limits: 30 psig (2.067 bar) continuous to either pressure connection. Temperature Limits: 20 to 120°F (-6.67 to 48.9°C). Size: 2-1/16˝ (52.39 mm) diameter dial face. Mounting Orientation: Diaphragm in vertical position. Consult factory for other position orientations. Process Connections: Barbed, for 3/16˝ ID tubing (standard); 1/8˝ male NPT (optional). Weight: 6 oz (170.1 g). Agency Approvals:RoHS. A. The standard Minihelic®II gage is supplied with two barbed pressure taps molded into the rear housing of the gage. These connections allow easy, fast connection to the gage using 3/16˝ ID rubber or plastic tubing. B. For applications in systems having higher total operating pressures, optional male 1/8˝ NPT pressure connections can be supplied. Note: The oblong over-pressure vent hole on the back of the gage at the right of the connections. This vent is sealed by a membrane molded in conjunction with the diaphragm and will blow out at approximately 75 psi. CAUTION: For use only with air or compatible gases. RoHS 010_Layout 2 8/14/13 1:38 PM Page 10 Differential Pressure GagesPRESSURE11 Housing is molded from strong mineral and glass filled nylon. Pointer stops of molded rubber prevent pointer over-travel without damage. Full view lens is removable and molded of acrylic. Aluminum scale litho-printed black on white, enhances readability. Red tipped aluminum pointer,rigidly mounted to helix is easy to see. Wishbone assembly provides mounting for helix, helix bearings, and pointer shaft. Jewel bearings provide virtually friction-free helix motion. Helix is free to rotate in jewel bearings. It aligns with magnetic field of magnet to transmit pressure indications to pointer. Zero adjustment screw, located behind the removable lens, eliminates tampering. Range spring calibration clamp fixes live length of spring for proper gage calibration and is factory set and sealed. Silicone rubber diaphragm allows accurate response to a broad range of temperatures and at extremely low pressure. Incorporates blow out area for overpressure protection. Diaphragm support plates of lightweight aluminum on each side of the diaphragm minimize position or attitude sensitivity and help define pressure area. Flat leaf range spring reacts to pressure on the diaphragm. Live length is adjustable for calibration. Small amplitude of motion minimizes inaccuracies and assures long life. Low pressure tap connects to rear chamber. Coil spring link provides a resilient connection between the diaphragm and the range spring. Ceramic magnet mounted on a molded bracket at the end of the range spring rotates the helix without direct mechanical linkage. High pressure tap connects with the front chamber through passageway in the plastic case and a sealing ring molded into the edge of the diaphragm. Simplicity of Design Ensures Reliable Operation Mounting hardware is supplied with the Minihelic®II gage for panel mounting through a single hole, 2-5/8˝ (67 mm) in diameter. Panel thickness up to 1/2˝ (13 mm) can be accommodated with the hardware supplied. If necessary, surface mounting of the gage can be accomplished by means of two 4-40 screws into the tapped mounting bracket stud holes in the rear of the gage. Surface mounting requires clearance holes in the panel for the two pressure taps.
