【 Product Introduction 】
This product named Photoelectric 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 don’t affect the smoke into it. While have no smoke, the diode can receive very weak infrared light. When the smoke entering the detector, the diode can receive strong infrared light. Through Light-Electric signal transform, the detector can send alarm signal.
