How smoke alarms work

This small toolbar alert and warning people to stay away from the danger area when smoke detectors.
This product named photoelectric detector (hereinafter detector) detects smoke by two infrared diodes. The principle of disclosure is granular in smoke can reflect infrared light. Infrared diodes are placed in a special room. The room can external light shield, but did not affect the smoke.
While no smoke, no infrared light diode receive very weak. When smoke enters the room, the diode can be more light and more, when a certain intensity, smoke can give out to detect an alarm signal. In order to reduce interference and low power consumption, emitting a pulse signal depends.
Detector design special structure and adopts the ASIC, with dust-resistant, mothproof outside intervention feature light etc.
Appropriate detector of smoke detectors in the home, shop, hotel, restaurant, Office building, school, Bank, library, computer House, etc.
