Apollo Fire Detectors Detector Smoke Optical Alarmsense

This type of smoke detector works by a Infrared LED pulsating its beam on the smoke particles and when the Infrared beam reflects of it, the photodiode light receptor recieves it and sends a signal to the circuit which sounds the alarm. · · · Responds well to slow-burning, smouldering fires · · Well suited for bedrooms and escape routes · · 360°C visibility of LEDs · · Reduces false alarms · · Quick and simple installation · · Works using the light scatter principle · · Detector changes to alarm state at a pre-set threshold of smoke penetration into the sensing chamber
