Optical(Photoelectric) Smoke Detector- for 12VDC Security System


Optical(Photoelectric )smoke detector responds to smoke. It has a chamber inside consists of a “light-emitting diode (LED)” that constantly shoots a beam of light and a “photocell” that senses light from darkness. In peacetime, the “photocell”can not senses the beam of light form the “light-emitting diode (LED)”. When there is smoke into the chamber of detector ,the beam of light is scattered by smoke particles, and the scattered light hit the“photocell”, thus the alarm is initiated.
