IRB-MON
™
Universal UL325 Thru Beam Photoeye
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). 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. Install the IRB-MON according to
instructions from the gate or door operator manufacturer. Comply with all applicable codes
and safety regulations.
