The D340 Air Duct Smoke Detector Housing is designed to mount to the ducts of HVAC systems to monitor the presence of smoke in the conditioned air. It is designed to work with two-wire photoelectric and ion smoke detectors. The efficient housing design samples the air passing through a duct and allows the detection of a potentially hazardous condition. When smoke is detected, the detector sends an alarm signal to the control panel and/or HVAC control equipment which will initiate the necessary action to control air handling systems.
