Sampling tubes are installed into the duct and air is directed to a 4098-9714EA smoke sensor mounted in the housing. These duct housings provide the high reliability performance of TrueAlarm analog sensing featuring programmable sensitivity, consistent accuracy, environmental compensation, status testing, and monitoring of sensor dirt accumulation. The TrueAlarm Duct Sampling Unit require only two
wires for both communications and power.
