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.

Product feature
● Test by hand
● Auto reset
● Asic adopted
● Anti-light
● Strong adaptability for circumstance
● SMT design, high stability
