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.
