CAUTIONS AND WARNINGS
This product is an accessory or part of a system. Always read and follow the
manufacturer’s instructions for the equipment you are connecting this product to.
Comply with all applicable codes and safety regulations. Failure to do so may result
in damage, injury or death!
1. Read and follow all operation 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
GENERAL DESCRIPTION
The IRB-HB is a safety photo beam and may be used as 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-HB provides a signal to the gate or
door operator that the beam is not obstructed. The operating range is up to 115ft. The IRB-HB
operates over a wide range of 6-35VDC.
A green alignment indicator on the receiver provides status information at a glance, making set-up
and alignment easy.
The IRB-HB includes two selectable operating configurations providing compatibility with most
operators that accommodate monitored external entrapment protection devices per UL325-2010.
Refer to operator installation instructions for proper configuration selection:
 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.

INSTALLATION
Install the IRB-HB 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. Disconnect the IRB-HB 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-HB power supply per requirements indicated in the specification table.

IRB-HB Instructions 4
Document no. 10280204 REV 1.3
4. Connect power to the terminals on the transmitter marked “TX”, polarity is not required.
Refer to your gate operator instructions for proper photo eye connections.
5. Connect power to terminals marked “POWER INPUT” on the receiver, marked “RX” polarity
is not required. Refer to your gate operator instructions for proper photo eye connections.
6. The IRB-HB 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.
7. The IRB-HB 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.
VERIFY INSTALLATION AND OPERATION
Verify proper operation of the IRB-HB 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-HB transmitter and receiver in line of sight and apply power.
2. Place an obstruction (ex. hand) between the IRB-HB 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-HB does not respond to the obstruction, lower the sensitivity by adjusting the
SENSITIVITY pot counter-clockwise.
5. If the IRB-HB indicates an obstruction when there is no obstruction, increase the sensitivity
by adjusting the SENSITIVITY pot counter-clockwise.
6. Follow gate/door manufacturer’s installation instructions and safety checks to verify that the
IRB-HB is operating properly.

TROUBLESHOOTING GUIDE
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
Red detect LED stays on
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
Check wires and terminal
connections to make sure they
are good
