IRB-MON Operating Instructions 2
Document no. 10280104
Cautions and Warnings
1. Read and follow all operating and Installation instructions.
2. Always follow gate operator manufacturer installation instructions regarding
installation of TYPE B1 sensor to the operator.
3. Disable the gate so it is unable to move.
Refer servicing to qualified service personnel.
IMPORTANT:
This product is an accessory or part of a system. Always read and follow the manufacturer’s
instructions for the equipment before connecting this product. Comply with all applicable
codes and safety regulations. Failure to do so may result in damage, injury or death.
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.

IRB-MON Operating Instructions 9
Document no. 10280104
Installation
Install the IRB-MON according to instructions from the gate operator
manufacturer. The intent of External Entrapment Protection Device Type
B1 non-contact sensor is to protect a person from being accidentally
injured by the moving gate or door.
DO NOT USE 12-24VAC IN PULSE CONFIGURATIONS.
1. Disconnect the IRB-MON from power before installing or servicing the device.
2. Always follow the instructions of the gate operator manufacturer regarding installation of type
B1 sensors on the gate operator. The instructions of the gate operator manufacturer always
supersede any instructions given in this or any other instructions by EMX Industries Inc.
3. Connect the IRB-MON power supply per requirements indicated in the specification table.
4. When using the relay outputs, do not exceed the voltage/current ratings indicated in the
specification table.
5. Connect power to the terminals on the transmitter marked “TX”, polarity is not required.
6. Connect power to terminals marked “POWER INPUT” on the receiver, marked “RX” polarity is
not required.
7. FOR CONFIGURATION 0 ONLY. Operators that require normally closed contact for
entrapment protection, connect terminal NC and COM to the designated terminals in the gate
operator. Operators that require normally open contact for entrapment protection, connect
terminals COM and NO to the designated terminals in the gate operator.
8. Install the IRB-MON according to instructions from the gate operator manufacturer. The intent
of External Entrapment Protection Device Type B1 non-contact sensor is to protect a person
from being accidentally injured by the moving gate or door.
9. The IRB-MON is housed in a NEMA 4X enclosure. To insure the integrity of the enclosure make
sure the covers are attached and closed tight using all four plastic screws provided. The wiring
to the enclosure must enter via UL Listed watertight fitting such as a strain relief or watertight
conduit connector.
10. The IRB-MON must be powered by Class 2 circuits only, wiring must be segregated from other
circuits or insulation must be provided that is suitable for the highest voltage for those circuits.
11. NOTE: REDUCE SENSITIVITY (COUNTER-CLOCKWISE) WHEN INSTALLING AT <20 FT.

Verification and operation
Verify proper operation of the IRB-MON according to instructions from the
gate operator manufacturer. The intent of External Entrapment Protection
Device Type B1 non-contact sensor is to protect a person from being
accidentally injured by the moving gate or door.
1. Verify that the IRB-MON transmitter and receiver in line of sight and apply power.
2. Place an obstruction (ex. hand) between the IRB-MON transmitter and receiver. The green LED
on the receiver is flashing. Check the operator control board that the safety input is actuated.
3. Remove the obstruction and green LED will be on.
4. If the IRB-MON does not respond to the obstruction, lower the sensitivity by adjusting the
SENSITIVITY pot counter-clockwise.
5. If the IRB-MON indicates an obstruction when there is no obstruction, increase the sensitivity
by adjusting the SENSITIVITY pot clockwise.
6. Follow gate/door manufacturer’s installation instructions and safety checks to verify that the
IRB-MON is operating properly.

Troubleshooting
Symptom
Possible cause
Solution
Does not detect obstruction
of beam
Sensitivity too high
Signal is reflecting off another
surface
Adjust SENSITIVITY pot
counter-clockwise
Check area for highly reflective
surfaces
Green LED flashes
continuously (indicating an
obstruction when an
obstruction is not present)
Sensitivity too low
Transmitter does not have
power
Receiver does not “see”
transmitter
Adjust SENSITIVITY pot
clockwise
Check power source for
transmitter
Make sure transmitter and
receiver have line of sight
alignment
Receiver activates but does
not transmit signal to
operator
Faulty connection between
receiver and operator control
input
Verify all wires and terminal
connections
Receiver green LED off (1)
Transmitter too close to
receiver
Adjust SENSITIVITY pot
counter-clockwise
Increase distance between
transmitter and receiver
(1) When transmitter is too close to the receiver the green LED will turn off, this prevents
mounting the photo eyes in close proximity.
