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.
