Intoduction:This photoelectric smoke detector detects 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 exteral light, but
doesn't affect the smoke into it. While there is no smoke, the
diode can receive very weak infrared light. When the smoke entering
the chamber, diode can receive more and more light, and the
detector can give out alarm signal when the smoke attains the
certain density. In order to reduce the interference and lower
power consumption, the emitting circuit adopts the pulse signal.
The photoelectric smoke detector in accordance with the networking
approach is divied into 2-wire and 4-wire photoelectric smoke
alarm. Technical Data:Category2 wires/4wiresOperation
