smoke detector

This product named Photoelectric detector detects the smoke by acouple of infrared diodes. This product named Photoelectric detector detects the smoke by acouple of infrared diodes.The principle of detecting is granule in the smoke canreflecti nfrared light.Infrared diodes are placed in the specialchamber. The chamber can shield external light,butdon'taffect the smoke in to it.While have no smoke,the diode canreceive very weaki nfrared light.When the smoke entering thechamber,diode can receive more and more light,when thesmoke at tains the certain density,the detector can give outalarm signal.In order to reduce the interference and lowerpower consumption,the emitting circuit adopts the pulsesignal.The detector adopts the special structure design andASIC,has the dust proof,moth proof and anti outside lightinterference feature etc.The detector is suitable for detect thesmoke in house,shop,hotel,restaurant,office building,school,bank,library,computer house and storehouse etc.
