Long range smoke detector beam system
Beam system Fire Detector is a Long-interval reflection line infrared beam system , which must be used together with a reflector.
In case of smoke on the light path of the detector, the signal arriving at the receiver is reduced;
--when the light reduction rate reaches the preset threshold, the detector will produce the alarm signal;
--when the light beam is completely blocked, the detector will produce the fault signal to prevent the false alarm caused by non-fire blockage.
