Simplex 4098-9714 TrueAlarm Photoelectric Sensor / Detector  0742444CN

The Simplex 4098-9714 TrueAlarm photoelectric sensors use a stable, pulsed infrared LED light source and a silicon photodiode receiver to provide consistent and accurate low power smoke sensing.  Seven levels of sensitivity are available for each individual sensor, ranging from 0.2% to 3.7% per foot of smoke obscuration.  Sensitivity is selected and monitored at the fire alarm control panel.

The sensor head design provides 360° smoke entry for optimum response to smoke from any direction.  A built-in screen keeps insects from entering the smoke chamber.  Due to its photoelectric operation, air velocity is not normally a factor, except for impact on area smoke flow.

This photoelectric detector can be used with the 4010 and 4100U series control panels from Simplex. It also is compatible with the 4008, 4020, 4210, and 4100 series, as well as with 2120 TrueAlarm CDT’s. This high-quality sensor will ensure your system is always in proper working order, so place your order today and we’ll ship it to you immediately.
