Simplex 4098-9756 Duct Sensor Housing P/N: 0631149

In the first place, the Simplex 4098-9756 air duct smoke sensor housings provide TrueAlarm operation for the detection of smoke in air conditioning or ventilating ducts. Also, sampling tubes are installed into the duct allowing air to be directed to the smoke sensor mounted in the housing.

In fact, monitoring each Simplex 4098-9756 photoelectric sensor’s average value provides a software filtering process that compensates for environmental factors (dust, dirt, etc.) and component aging, providing an accurate reference for evaluating new activity. Besides, The result is a significant reduction in the probability of false or nuisance alarms caused by shifts in sensitivity, either up or down.
