Description
Model:DCPS
Operated by a change in the amount of light that is tangent to the photoelectromagnetic device as air enters, including a certain amount of smoke (due to fire). When the sensor is energized, it produces a pulse of 50 μs per second, during which it is illuminated. At this time, scattered light is generated by smoke coming into the darkroom, and the voltage generated by the amount of light detected in the light field is higher than the reference voltage, which causes a fire signal.
