The ISC-FPB1-W60QS, ISC-FPB1-W120QS and ISC-FPB1-W200QS are quad-beam
photoelectric detectors designed for indoor and outdoor applications. Consisting of a
separate transmitter and receiver, an alarm is activated when a person passes through all four
beams. Combination of features and adjustable parameters allow for better catch
performance, lower false alarm rates and reduced effects of environmental disturbances.
For stable operation, the detectors are equipped with the following feautres:
100% Sensitivity Allowance
Maintains stable operation even if 99% of beam energy is cut, for example by rain, fog, frost,
and so on.
Quad Beam Detection
Fewer false alarms caused by birds and other small animals because all four beams must be
blocked simultaneously to cause an alarm.
Beam Power Control
Select the appropriate beam intensity relative to the detection range to minimize reflection on
nearby walls and cross-talk with other detectors.
Beam Interruption Time Control
Use to change the beam interruption time to best fit the application.
