Particularly appropriate for protecting area from 10 – 100 meters. The system comprises of three parts:
The transmitter, the receiver and the circuit control system. The transmitter projects modulated infrared beams ( 880 nm ) sent to the receiver through reflectors. Reduction of infrared’s intensity in case of smoke, is detected from the circuit control system and from the loop is transmitted to the control panel. Four sensitivity settings within the alarms limit of 25%, 35%, 50%, 65% coverage per meter.
Loop activates both the circuit control system and the receiver which can also be powered to initiate its functions from other sources within the range of 17 Vdo – 28 Vdo.
