Product Overview
The IRB-MON is a thru-beam photo eye and is an external entrapment protection device type
B1, 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). The IRB-MON provides a signal to the
gate or door operator that the beam is not obstructed. The operating range is up to 115ft. The
IRB-MON operates over a wide range of 6-35VDC and 12-24VAC.
A green alignment indicator on the receiver provides status information at a glance, making
set-up and alignment easy.
The IRB-MON includes 3 selectable operating configurations providing compatibility with most
operators that accommodate monitored external entrapment protection devices per UL325-
2016.
REFER to operator installation instructions for proper configuration selection.
CONFIGURATION 0 - NON-MONITORED and MONITORED
Intended for use with operators that require simple relay contact activation to
indicate beam obstruction. Reference Light ON/Dark ON setting. Jumper
available for compatibility with Normally Open 10K termination operators.
CONFIGURATION 1 – MONITORED, HEARTBEAT 300Hz / 0Hz
Intended for use with operators designed to accept a “heartbeat” form of
monitoring, 300Hz when aligned, no obstruction, 0Hz when beam is obstructed.
CONFIGURATION 2 – MONITORED, HEARTBEAT 300Hz / 2Hz / 0Hz
Intended for use with operators designed to accept a “heartbeat” form of
monitoring, 300Hz when aligned, no obstruction, 2Hz when beam is obstructed,
and 0Hz for a failure.
