FOUR-WIRE DUCT SMOKE DETECTOR HOUSING


The D341 Four+wire duct smoke detector housings mount on the ducts of heating, ventilation, and air conditioning (HVAC) systems. The D285DH detector in the housing monitors the presence of smoke in the conditioned air. The housing works with all 24 VDC or VAC or 120 VAC, UL Listed four+wire control panels. 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.

D341 Alarm/Trouble Indication

A D344+RT, a D344+RL, or a DRA+5 can provide remote LED indication of alarm and trouble status. The red LED lights for an alarm. An open loop causes the yellow Trouble LED to flash.
