Bosch ISC-FPB1-W120QF 4-Channel Photoelectric Quad Beam Detector

Bosch ISC-FPB1-W120QF 4-Channel Photoelectric Quad Beam Detector

The Photobeam 5000 Series consists of the single channel quad beam ISC-FPB1-W60QS, ISC-FPB1- W120QS, ISC-FPB1-W200QS, and the four channel quad beam ISC-FPB1-W60QF, ISC-FPB1-W120QF, and ISC-FPB1-W60QF detectors with separate transmitters and receivers. The detector series uses four pulsed infrared beams that are designed to activate an alarm when all four beams are simultaneously blocked. False alarm immunity is increased by the utilization of four beams compared to single or dual beam models. The detector series also features interlocked upper and lower beams, signal voltage LED, and optional environmental discrimination circuitry.

Consisting of a separate transmitter and receiver, it is designed to activate an alarm when an intruder passes within the direct line of sight between the transmitter and receiver.

This feature allows an added level of detection by generating an alarm when four beams from two units are blocked simultaneously. Environmental conditions require higher false alarm tolerance against smaller objects passing through the detector's line of sight. To do this, set the AND/OR gate option to AND gate mode that only causes an alarm condition when all four infrared beams are interrupted simultaneously. High Security applications might require the detection of smaller objects passing through the detector's line of sight. To do this, set the AND/OR gate option to OR gate mode that causes an alarm condition when either the upper two beams or the lower two beams are interrupted.
