Product details

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.

Features

include an ICC current limiter. The current limiter eliminates power-on false alarming. The oscillator controls the IR LED excitation frequency and provides drive to the synchronous detector. The synchronous detection method has very high noise rejection performance. The internal latch is capable of sinking 100 milliamps maximum and will clamp the VCC pin to 5 volts when tripped. The latch current is determined by an external resistor typically located in the master panel and is reset by tempora.
