smoke detector

This product named Photoelectric detector detects the smoke by acouple of infrared diodes.The principle of detecting is granule in the smoke can
reflecti nfrared light.Infrared diodes are placed in the special
chamber. The chamber can shield external light,butdon't
affect the smoke in to it.While have no smoke,the diode can
receive very weaki nfrared light.When the smoke entering the
chamber,diode can receive more and more light,when the
smoke at tains the certain density,the detector can give out
alarm signal.In order to reduce the interference and lower
power consumption,the emitting circuit adopts the pulse
signal.The detector adopts the special structure design and
ASIC,has the dust proof,moth proof and anti outside light
interference feature etc.The detector is suitable for detect the
smoke in house,shop,hotel,restaurant,office building,
school,bank,library,computer house and storehouse etc.
