Specification

The Photoelectric smoke detector is detect the smoke by
couple of infrared diodes. The principle of detecting is
granule in the smoke can reflect infrared light.
In order to reduce the interference and lower power
consumption, the emitting circuit adopt the pulse signal.
The smoke detector adopts the special structure design
and ASIC, has thr dustproof, mothproof and anti outside
light interference feature and etc.
-10 0C ~ 55 0C
0 - 95 % RH
80 Square meter
ø 104 x 49 mm
Infrared diodes are placed in the special chamber. The
chamber can sheild 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 entering the chamber,
diode can receive more and more light, when the smoke
attains the certain density, the
