This product is a photoelectric smoke detector (hereinafter referred to as the detector) is by using the principle of particle refractive infrared smoke of fire detection, circuit is mainly composed of an infrared transmitting part and receiving part, the launch tube and receiving tube is placed in the optical labyrinth maze, optical interference shielding external stray light, but does not affect the smoke into. In the free state, receiving tube receiving only a very weak light, when the smoke enter, because the scattering effect, the received optical signal enhancement, when the smoke reaches a certain concentration, detector output alarm signal. In order to reduce interference and reduce power consumption, emission circuit using pulse mode, can improve the transmitting tube service life. Products with dust, insects, resistance to external light interference and other functions, to ensure the stability of the product. Function characteristics: • • • • manual test automatic reset • • using special microprocessor control
• • dustproof, insect resistant, anti white light interference, strong environmental adaptability
• • using SMT process, good stability
• • using SMT process, good stability
