The working principle of photoelectric pyrotechnics
The emission tube and the receiving tube are placed in the optical labyrinth. The optical maze can shield the external stray light interference, but does not affect the smoke into the smoke-free state. The receiving tube receives only the weak infrared light. When the smoke enters, , The received optical signal enhancement, when the smoke reaches a certain concentration, the detector output alarm signal. In.
The launch tube and the receiving tube are placed in the optical labyrinth, and the optical maze shields the external stray light interference without affecting the smoke.
Photoelectric smoke detectors referred to as detectors, is the use of smoke particles in the principle of refraction infrared light detection of fire, the circuit mainly by the infrared emission part and accept the part of the composition
