Wireless Smoke Detector This product named Photoelectric 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. It reacts very quick to visible smoke released by smoldering fire and flaming fire, and suitable for fire alarm in house, factories, shopping malls, restaurants, office buildings, banks, libraries, etc. Features: Size: 10.5×10.5×3.5cm White color Excellent stability. High sensitivity. Alarm test button for easy testing. Low battery indicator Designed for the fastest possible installation. These small devices will alert and warn people to stay away from the danger field when they detect smoke. This product called photoelectric detector (hereinafter called detector) detects smoke by a pair of infrared diodes. The detection principle is that the granules in the smoke can reflect infrared light. Infrared diodes are placed in the special chamber. The camera can shield the external light, but does not affect the smoke in it. Although it is smokeless, the diode can receive very weak infrared light. When the smoke enters the chamber, the diode can receive more and more light, when the smoke reaches a certain density, the detector can emit an alarm signal. To reduce interference and reduce power consumption, the emitter circuit adopts the pulse signal. The detector adopts the special structure design and ASIC, it has the function of dustproof, mothproof and anti outside light interference, etc. The detector is suitable for detecting smoke in house, shop, hotel, restaurant, office building, school, bank, library, computer house and warehouse, etc. …
