Nor are they a substitute for early warning in a building’s regular fire detection system.  \nSystem Sensor supports this position and strongly recommends that the user read NFPA Standards 90A, 72, and 101. The D2 Air Duct Smoke Detectors are listed per UL 268A.  \nThis device will not operate without electrical power. Fire situations may cause an interruption of power. The system safeguards should be discussed with your local fire protection specialist.  \nThis device will not sense smoke unless the ventilation system is operating and the cover is installed.  \nFor this detector to function properly, it MUST be installed acc","cbCaimgdebHW53CC","https://ap.wps.com/l/cbCaimgdebHW53CC","pdf",1054718,"English","# Limitations of Duct Smoke Detectors\n# General Description\n## Detector Feature Set\n# Contents of the Duct Smoke Detector Kit\n# Exploded View of Duct Smoke Detector Components\n# Detector Installation\n## Verify Duct Air Flow Direction and Velocity","[{\"question\":\"What are the key operating and storage temperature ranges for the D2 duct smoke detector?\",\"answer\":\"Operating temperature is −4°F to 158°F (−20°C to 70°C), and storage temperature is −22°F to 158°F (−30°C to 70°C).\"},{\"question\":\"What does the manual state about using duct smoke detectors?\",\"answer\":\"DUCT DETECTORS MUST NOT BE USED AS A SUBSTITUTE for open area detector protection or as a substitute for early warning in a building’s regular fire detection system.\"},{\"question\":\"How often should the detector be tested and cleaned?\",\"answer\":\"The detector must be tested and maintained regularly following NFPA 72 requirements, and it should be cleaned at least once a year.\"}]","I56-3050-001R - Installation and Maintenance Instructions - D2 Duct Smoke Detector | PDF",15]
