Document no. 10350104
1. Disconnect the IRB-325 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. The IRB-325 has to be powered by 12V –24V AC/DC 150mA power supply.
4. Do not connect the IRB-325 output to loads higher than 1A @ 30V AC/DC.
5. Connect power to terminals 1 and 2 on IRB-325 transmitter marked “TX” polarity is not
important.
6. Connect power to terminals 4 and 5 marked “power input” on the IRB-325 receiver, marked “RX”
polarity is not important.
7. For operators that require normally closed contact for entrapment protection, connect
terminals 1 (NC) and 2 (COM) to the designated terminals in the gate operator.
8. For operators that require normally open contact for entrapment protection, connect terminals
2 (COM) and 3 (NO) to the designated terminals in the gate operator.
9. Install the IRB-325 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.
10. The IRB-325 is housed in a NEMA 4X enclosure.
To insure the integrity of the enclosure make sure
the covers are attached and closed tight with the
help of four plastic screws provided. The wiring to
the IRB-325 Enclosure has to enter via watertight
strain relief or watertight conduit connector.
11. The IRB-325 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.
