The D340 Two‐wire duct smoke housings mount on the ducts of heating, ventilation, and air conditioning (HVAC) systems. The housing works with the D285DH Duct smoke head. The D285DH detector in the housing monitors the presence of smoke in the conditioned air.
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. The control panel or HVAC control equipment initiates the necessary action to control air handling systems.
