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.
Retro-reflective photo-eyes rely on a reflective surface (a reflector) for proper
operation.
In some cases a vehicle with reflective surface at a given distance can act as a
reflector and allow the gate to close on a vehicle.
EMX Industries Inc. assumes no responsibility in this case and all the risks are on the installer,
designer and user of the gate system with a retro-reflective photo-eye.
In case such a risk is not acceptable, EMX Industries Inc. strongly recommends the use of thru-
beam type of a photo-eye.
Product Overview
The IRB-RET retroreflective photo eye 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). Since the reflector directs the beam back to the
photo eye, wiring to the other side of the roadway is not required. The IRB-RET provides a
signal to the gate or door operator that the beam is not obstructed. The operating range is up
to 60ft. The IRB-RET operates over a wide range of 6-40VDC and 12-24VAC (dependent on
configuration selection).
A red alignment indicator on the receiver provides status information at a glance, making set-
up and alignment easy. A green LED indicates power.
The IRB-RET includes 3 selectable operating configurations and provides 5 monitoring options
for compatibility with most operators that accommodate monitored external entrapment
protection devices. The IRB-RET complies with UL325 requirements effective August 1, 2018.
Refer to operator manufacturer’s instructions to assure compatibility.
REFER to operator installation instructions for proper configuration selection
