Two-wire Duct Smoke Detector Housings. The D340 Duct Smoke Detector Housings mount on the ducts of heating, ventilation, and air conditioning (HVAC) systems to monitor the presence of smoke in the conditioned air. The housing works with the D285DH Photoelectric Duct Smoke Detector Head. The efficient housing design samples the air passing through a duct and detects potentially hazardous conditions. When smoke is detected, the detector sends an alarm signal to the control panel or HVAC control equipment that initiates the necessary action to control air handling systems.
