Cautions and Warnings
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.
WARNING ... Not to be used for Personnel Protection
Never use product as sensing devices for personnel protection. Doing so could cause serious
injury or death. These sensors do NOT include the self-checking redundant circuitry necessary
to allow their use in personnel safety applications. A sensor failure or malfunction can cause
either an energized or de-energized sensor output condition. UL 325 Non-compliant
Product Overview
The IRB-4X is used as a safety, reversing, or opening device when used in conjunction with automatic
operators, garage doors, rolling doors and parking barriers. Its generous 24osensing angle makes this
reliable photoeye easy to align. The use of the hoods is recommended to prevent distortion from rain
on the lens area.

IRB-4X Transmitter connections (figure 1)
1. Connect power (12 –24V AC/DC) to Power
input terminals (no polarity) LED2 Power LED will
glow green when powered.
IRB-4X Receiver connections (figure 2)
Terminal output connections from left to right are:
Normally closed, Common, Normally open, Power, Power
1. Connect power (12 –24V AC/DC to Power input terminals (no polarity)
2. Connect the Common to the operator control terminal per manufacturer
3. Connect either the Normally open or Normally Closed as needed to the
Control input terminal specified by the operator manufacturer.
4. The Power LED will glow green when powered.
5. Adjust sensitivity potentiometer as needed by turning counter clockwise
to increase gain. (range is 3 to 115 feet). (see arrow)
6. The detect Led will glow red when an obstruction occurs.
7. On some variable frequency drives and noisy installations, it may be necessary
to connect the bottom right mounting hole labeled
“Earth Ground” to a wire connected to earth ground.
* Do not connect unless necessary
Use minimum gain setting needed to achieve reliable detection.

Troubleshooting
Symptom
Possible cause
Solution
Holds gate open
1. No power on transmitter
or receiver
2. Transmitter not working
3. Receiver not working
4. Sensitivity set too low
1. Check power LEDs and power source
2. Install new transmitter
3. Install new receiver
4. Adjust sensitivity
Does not
activate gate
1. Bad connection or broken
wires
2. Relay contacts burned or
stuck
3. Interference from local
source
4. Not Connected to correct
input terminals
5. Sunlight “blinding” the
receiver eye
1. Check wires and connections
2. Replace Receiver
3. See step 7 under Operational Settings
4. Check operator manual for terminals
5. Change position of receiver to a little
higher and tilt forward to shield the
sensor from the direct sunlight
Chattering
1. Interference
See step 7 under Operational settings
and see if any reflective surfaces could
be sending a signal into the receiver
sensor
