PRODUCT INTRODUCTION:
- This product, named a photoelectric smoke detector (hereafter called a detector), detects smoke using a pair of infrared diodes. The detection principle is that a granule in the smoke can reflect infrared light. Infrared diodes are placed in a special chamber. The chamber can shield external light but does not affect the smoke inside it. While there is no smoke, the diode can receive very weak infrared light. When the smoke enters the chamber, the diode can receive more and more light, and the detector can give out an alarm signal when the smoke reaches a certain density. To reduce interference and lower power consumption, the emitting circuit adopts a pulse signal. The product, in accordance with the networking approach, is divided into 2-wire and 4-wire detectors.
