Product description
It adopts the principle of infrared light refraction by the particles in smoke to detect the fire circuit.Mainly consists of infrared transmitter and receiver, the transmitter and receiver are placed in an optical labyrinth.The transmitter tube and receiver tube are placed in the optical labyrinth optical labyrinth can be shielded from outside interference with stray light, but does not affect the entry of smoke. interference, but does not affect the entry of smoke. In the smoke state, only receive a very weak Infrared light, smoke, due to the scattering effect, so that the receiving optical signal increase interference and reduce power consumption, the transmitter circuit adopts pulse mode, which can improve the life of the transmitter tube.
