The Simplex 4098-9714 TrueAlarm Photoelectric Sensor / Detector, designated as 0742444CN, employs a stable pulsed infrared LED light source and a silicon photodiode receiver. This combination ensures reliable and accurate low-power smoke detection. The sensor offers seven levels of sensitivity, customizable for each unit, ranging from 0.2% to 3.7% per foot of smoke obscuration. Sensitivity settings are configured and monitored at the fire alarm control panel.

The sensor head's design incorporates a 360° smoke entry feature, optimizing responsiveness to smoke from any direction. An integrated screen prevents insects from entering the smoke chamber. Air velocity typically does not impact the sensor's operation, except in terms of influencing area smoke flow.

This photoelectric detector is compatible with the 4010 and 4100U series control panels by Simplex. It also works seamlessly with the 4008, 4020, 4210, and 4100 series, in addition to the 2120 TrueAlarm CDTs.
