This product named Photoelectric detector (hereinafter
called detector) detects the smoke by a couple of infrared
diodes. The principle of detecting is granule in the
smoke can reflect infrared light. Infrared diodes
are placed in the special chamber. The chamber can shield
external light, but don’t affect the smoke into it. While have
no smoke, the diode can receive very weak infrared
light. When the smoke enters the chamber, the diode can
receive more and more light, when the smoke attains 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
detecting smoke in house, shop, hotel, restaurant, office
building, school, bank,
