Product Information
EMX IRB-325
The IRB-325 photoeye is used as an external entrapment protection device type B1 non-contact sensor for use with automatic gate operators. produces a detection signal to stop or reverse a door/gate. Can be used in sets to protect all areas of entrapment.

FEATURES:

• Complies with UL 325 Standard.
• The IRB-325 transmitter and receiver are mounted in line of sight at a distance of up to 65 feet.
• When the infrared beam is broken the IRB-325 produces detection signal.
• Powder coated steel hoods help protect from damage
• Sold as kit or as individual components

• Range: 6' to 65'
• Power: 12V to 24V AC/DC
• Relay Contacts: 30V 1A
• Dimensions: 5.03" High x 3.06" Wide x 3.02" Deep
• Housing: UL and CSA Type 4, 4X, 3, 3R, 12 13 Rating
• Operating Temperature: -40 degrees to 170 degrees Fahrenheit

• IRB-325-HD Protective Hoods
• IRB-325-PT Mounting Post - 4" x 4" base with (4) 1/2" holes, post is 2" square and 2' high
• IRB-325-SP Strain Relief Spout - watertight connector for interconnecting cord

1. Disconnect the IRB-325 from power before installing or servicing the device.
2. The IRB-325 must be connected to Class 2 circuits only, wiring must be segregated from other circuits or insulation must be provided that is suitable for the highest voltage of those circuits.
3. 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.
4. The IRB-325 has to be powered by 12V – 24V AC/DC 150mA power supply.
5. Do not connect the IRB-325 output to loads higher than 1A @ 28V AC/DC.
6. Connect power to terminals 1 and 2 on IRB- 325 transmitter marked “TX” polarity is not important.
7. Connect power to terminals 4 and 5 marked “power input” on the IRB-325 receiver, marked “RX” polarity is not important.
8. For operators that require normally closed contact for entrapment protection, connect terminals 1 and 2 to the designated terminals in the gate operator.
9. For operators that require normally open contact for entrapment protection, connect terminals 2 and 3 to the designated terminals in the gate operator.
10. 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.
11. 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.

OPERATING INSTRUCTIONS

1. Read and follow all operation instructions.
2. Always follow gate operator manufacturer operation instructions.
3. Disable the gate so it is unable to move.
4. With the IRB-325 mounted in place and powered, make sure the transmitter “TX” is in line of sight of the receiver “RX”.
5. Introduce an obstruction in form of a hand between the IRB-325 transmitter and receiver. Two Red LED’s on the receiver have to turn on. Check the operator control board that the safety input is actuated.
6. Remove the obstruction and the Red LED’s in receiver will turn off.
7. Should the IRB-325 fail to recognize the obstruction lower the sensitivity by moving jumpers J1 and J2 to lower position.
8. Should the two Red LED’s be turned on while there is no obstruction increase the sensitivity by moving jumpers J1 and J2 to a higher position.
