MONITORED RETRO-REFLECTIVE
PHOTOELECTRIC SENSOR
Model LMRRUL
To prevent possible SERIOUS INJURY or DEATH from a closing gate or door:
Read and follow ALL instructions.
Be sure to DISCONNECT ALL POWER to the operator BEFORE installing the photoelectric sensor.
The gate or door MUST be in the fully opened or closed position BEFORE installing the LiftMaster®
Monitored Entrapment Protection device.
Correctly connect and align the photoelectric sensor.
Install the photoelectric sensor so that the center of the sensor window is NO HIGHER than
4-1/2" (11.4cm) above the oor for door operators and 26" (66 cm) above grade for gate operators.
Monitored external entrapment protection devices MUST be installed per the operator installation
manual at each Entrapment Zone.
The sensor and refl ector MUST be mounted vertically.
Use the provided refl ector ONLY.
Test the gate operator and ALL photoelectric sensors monthly. Replace ANY damaged devices.
SAVE THESE INSTRUCTIONS.

Installation
IMPORTANT: The sensor and the re ector MUST be mounted vertically. Disconnect ALL power to the
operator.
1. Attach the mounting bracket to the post with 1/4"-20 screws. Drill a hole in the post through the center
hole in the bracket. Optional: If installing to a square post or fl at surface, you may attach the sensor
bracket directly to the post without using the mounting bracket. Make sure the location of the sensor
follows the specifi ed measurements. If installing multiple sensors in close proximity, mount the sensors on
opposite sides to avoid crosstalk.
2. Slide the bottom sensor bracket onto the studs of the mounting bracket and secure with 1/4"-20 lock nuts.
Make sure the bracket legs are facing down.
3. Loosely attach the top sensor bracket with 10-32x1" thread-locking screws. Make sure the slots are
facing up.
4. Place the sensor in the bracket and tighten the screws just enough to allow the sensor to rotate inside the
bracket.
5. Slide the hood over the sensor until it snaps into place. Secure hood with the M3 screw. The hood MUST
be installed on the sensor.
6. Route wires through the center hole of the mounting bracket and into the post. Optional: Use conduit with
NEMA 4X compatible 1/2"-14 NPT fi tting (not provided).
7. Place the refl ector in the refl ector hood.
8. Secure the refl ector and hood to the bracket with 8-32x1" screws. Secure the bottom of the refl ector to the
hood with 8-32x1" screws.
9. Mount the re ector a minimum of 3 ft. (.9 m) and maximum of 50 ft. (15.2 m) away from the sensor.

Wiring
Sensor wiring (red and black wires): Wire the photoelectric sensors (red [+] and black [-] wires) to the
appropriate inputs on the operator or expansion board as shown.
Heater wiring (green and white wires):
OPTION 1 - Connect to the ACCESSORY POWER ON terminal on the control board (NOT polarity specifi c).
OPTION 2 - Connect to an external 12V to 24V DC or AC power supply (not provided) with adequate current
to power all sensors.
OPTION 3 - For use with battery backup. Connect to ACCESSORY POWER ON and AUX RELAY terminals.
Set AUX RELAY switches as shown. In this confi guration, the heater will switch off during a power failure to
extend the battery life.
DO NOT overload the accessory power output on the control board or the external power supply.
NOTE: Heater feature is not recommended for ANY solar installations.
