Description
The CS235 System Smoke Detector is a photo electric type with a pulsed infrared LED as the light source and a silicon photodiode as the light detector. The CS235 IC, along with passive external compo nents, controls the system timing and signal processing.

Features
■ Synchronous Detection for High Noise Immunity
■ Pulsed Operation for Low Average Current Drain
■ System Gain Externally Set
■ System Sensitivity Externally Adjustable
■ System Operation Monitored by Means of External Red LED
