15 Install MyQ Remote LED Light
The MyQ Remote LED Light is designed to plug directly into a standard 230V outlet. Select an appropriate location on the ceiling or wall to mount
the light within 1.83 m of an electrical outlet so that the cord and light are away from moving parts. MyQ Remote LED Light installation is required to
enable MyQ and Timer-to-Close (TTC) operation.
NOTE: If installing light on drywall and a ceiling joist cannot be located, use drywall anchors provided. No pilot hole is required for drywall anchors.
1. Drill pilot holes 15.6 cm apart if mounting to joist.
OR
Screw in drywall anchors 15.6 cm apart if mounting to drywall.
2. Determine the length of power cord needed to reach the nearest outlet. Wind any excess cord around cord retainer on the top side of the light
base. Route the cord through the channel so the light mounts flush.
3. Open the light lens.
4. Mount the light with the screws provided (9+10).
5. Close the light lens.
6. Plug in the light to the outlet.
NOTE: The LED light is very bright. DO NOT stare at the light while on a ladder.
Your garage door opener remote light has already been programmed at the factory to operate with your opener.
Any additional or replacement remote lights will need to be programmed.

Electrical Connection

In order to avoid personal injury and damage to the device, the door opener should be operated only if such an instruction
is explicitly stated in this manual. The power plug must always be accessible for the purpose of disconnecting the mains
supply. Electrical installations may only be undertaken by an authorized electrician.

Installation of Photocells

IMPORTANT INFORMATION ABOUT THE INFRARED PHOTOCELLS
The instructions for installation are included in the scope of delivery of the infrared photocells and must be followed. The photocells ensure that the
door is open, or remains open, if people, especially young children, are in the door area. When properly connected and aligned, the infrared
photocells sensor will detect an obstacle in the path of its electronic beam. The sending sensor transmits an invisible light beam to the receiving
sensor. If an obstruction breaks the light beam while the door is closing, the door will stop and reverse to full open position, and the opener lights will
flash 10 times.
For use of MyQ or TTC feature the sensors must be installed the garage so that the sending and receiving sensors face each other across the door,
no more than 10 cm above the floor. Either can be installed on the left or right of the door as long as the sun never shines directly into the receiving
sensor lens. The invisible light beam path must be unobstructed. No part of the garage door (door tracks, springs, hinges, rollers or other hardware)
may interrupt the beam while the door is closing.
NOTE: Liftmaster recommends to install Infrared photocells on each installation. For use of MyQ or TTC feature the installation of Infrared photocell
are required.
WIRE THE INFRARED PHOTOCELLS
1. Run the wire from both sensors to the garage door opener. Attach the wire to the wall and ceiling with the staples.
2. Strip 11 mm of insulation from each set of wires. Separate the wires. Twist the white wires together. Twist the white/ black wires together.
3. Insert the white wires into the white terminal on the garage door opener. Insert the white/black wires into the grey terminal on the garage door
opener. To insert or remove the wires from the terminal, push in the tab with a screwdriver tip.
ENSURE THE INFRARED PHOTOCELLS ARE ALIGNED
The door will not close if the sensors have not been installed and aligned correctly.
When the light beam is obstructed or misaligned while the door is closing, the door will reverse and the garage door opener lights will flash ten times.
If the door is already open, it will not close. The sensors can be aligned by loosening the wing nuts, aligning the sensors, and tightening the wing
nuts.
1. Check to make sure the LEDs in both sensors are glowing steadily. The LEDs in both sensors will glow steadily if they are aligned and wired
correctly
TEST THE INFRARED PHOTOCELL
1. Open the door. Place an obstruction in the path of the door.
2. Press the remote control push button to close the door. The door will not move more than 2.5 cm, and the garage door opener lights will flash 10
times.
The garage door opener will not close from a remote control if the LED in either infrared photocell is off (alerting you to the fact that the sensor is mis-
aligned or obstructed). If the garage door opener closes the door when the infrared photocell are obstructed (and the sensors are no more
than 10 cm above the floor), call for a trained door systems technician.
