FAAC Photo Eye Retroreflective | FAA-2800

The IRB-RET retroreflective photo eye is an external entrapment protection device type B1, a non-contact sensor for use with automatic gates and doors. The light beam is near-infrared and pulses at a rate of 300/second (300Hz). Since the reflector directs the beam back to the photo eye, wiring to the other side of the roadway is not required. The IRB-RET provides a signal to the gate or door operator that the beam is not obstructed. The operating range is up to 60ft. The IRB-RET operates over a wide range of 6-40VDC and 12-24VAC (dependent on configuration selection).

A red alignment indicator on the receiver provides status information at a glance, making set-up and alignment easy. A green LED indicates power.

The IRB-RET includes 3 selectable operating configurations and provides 5 monitoring options for compatibility with most operators that accommodate monitored external entrapment protection devices. The IRB-RET complies with UL325 requirements effective Jan.12, 2016. Refer to operator manufacturer’s instructions to assure compatibility.

  • Reflector
  • Mounting bracket with hardware
  • Five monitoring interfaces:
    • Normally closed: Cycle power to the transmitter while monitoring the receiver contacts for proper operation
    • Two-wire pulsed (2 freq): Provides 300Hz “heartbeat” unobstructed, 0Hz obstructed over power supply lines
    • Two-wire pulsed (3 freq): Provides 300Hz “heartbeat” unobstructed, 2Hz obstructed, and 0Hz failure over power supply lines
    • Four-wire pulsed: Provides 300Hz “heartbeat” unobstructed, 0Hz obstructed over a separate connection
    • Resistive termination: Provides a measurable resistance when unobstructed
