• 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" (11.4cm) above the fl 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.

WARNING: This product can expose you to chemicals including lead, which are known

to the State of California to cause cancer or birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov.Installation IMPORTANT: The sensor and the refl 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

4. Place the sensor in the bracket and tighten the screws just enough to allow the sensor to rotate inside the

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 refl ector a minimum of 3 ft. (.9 m) and maximum of 50 ft. (15.2 m) away from the sensor.

NOTE: Heater feature is not recommended for ANY solar installations.Test Test ALL installed sensors for proper operation. Place an obstruction in the sensor beam path and run the operator. The gate will stop and reverse. If the gate does not stop and reverse, refer to Troubleshooting below. Perform the test with the obstruction in three locations:

• Halfway between the refl ector and sensor

Set screw Sensor bracket screw Blue LED Solid blue indicates optimal alignment Red LED indicates misaligned or blocked sensor Alignment Reconnect power to the operator.

1. Align the sensor. The red LED indicates a misaligned or blocked sensor. The blue LED indicates signal

strength. Slow blinking indicates weak signal. Fast blinking indicates stronger signal. Solid blue LED indicates optimal alignment.

2. When the sensor is optimally aligned, tighten the sensor bracket screws to secure the sensor in place

(about 24in-lb of torque). For extra security, tighten with the set screw until it grips the sensor.

3. Place the wire cover onto the sensor bracket. Make sure the tabs on the wire cover slide into the slots on

the top of the sensor bracket. Secure the wire cover with 8-32x3/8" screws. Wire cover is NOT intended for use with conduit installations.NOTICE: This device complies with Part 15 of the FCC rules and Industry Canada’s license-exempt RSSs.

5. Gently clean the sensor and refl ector with a soft towel; make

sure sensor heater is connected. Blinking Blue LED 1. Sensor is not optimally aligned

2. Sensor is too far from refl ector

3. Refl ector or sensor lens is dirty

1. Align the sensor until the blue light is solid

2. Decrease the distance between the sensor and refl ector

3. Gently clean the sensor and refl ector with a soft damp towel

Blinking Red LED Incorrect wiring or over voltage Check for proper connection of sensor wiring. Red/Blue LEDs blinking together Internal memory fault Disconnect all power, wait 15 seconds, then reconnect power. If issue continues, replace sensor. Red/Blue LEDs alternate blinking Internal fault Disconnect all power, wait 15 seconds, then reconnect power. If issue continues, replace sensor.
