AS SD201 4L Conventional 4 Wire Smoke Detector

AS-SD201 is a Conventional Photoelectric smoke detector, In accordance with the networking approach is divided into 2-wired and 4-wired detectors. 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 enter the chamber, diode can receive more and more light, and the detector can give out alarm signal when the smoke allains the certain density. In order to reduce the interference and lower power consumption, the emitting circuit adopts the pulse signal.
