Instruction Manual
The IRB-MON thru beam infrared photoeye is an external entrapment protection device type B1,
non-contact sensor for use with automatic gates and doors. The photoeye provides a signal to the gate
or door operator that the beam is or is not obstructed. The IRB-MON operates up to 115 feet over a
wide range of voltages (6-35 VDC and 12-24 VAC). A green alignment indicator on the receiver provides
status information at a glance, making set-up and alignment easy. The IRB-MON provides compatibility
with most operators that accommodate monitored external entrapment devices per UL325.
Cautions and Warnings
This product is an accessory or part of a system.
instructions from the gate or door operator manufacturer. Comply with all applicable codes
and safety regulations.

    Then increase sensitivity setting one quarter turn. Confirm receiver LED is still on. 9. Place an obstruction (ex. hand) between the IRB-MON transmitter and receiver. The green LED on the receiver will flash. Check the operator control board and verify that the safety input is recognized by the operator.
