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 input voltages (6-35 VDC and 12-24 VAC).
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.

- Page 3 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.
