MANUAL FOR PHOTOELECTRIC SMOKE DETECTOR
PRODUCT INTRODUCTION
This product named Photoelectric smoke 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 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 product in accordance with the
networking approach is divided into 2-wire and 4-wire detectors.
