IMPORTANT INFORMATION ABOUT THE PHOTOELECTRIC SENSOR
Be sure power to the operator is disconnected.
When properly connected and aligned, the photoelectric sensor will detect an obstruction in the path of its
beam. If an obstruction breaks the beam while the door/gate is closing, the operator will stop and typically
reverse to the full open position.
The photoelectric sensor must be installed so that it faces the refl ector across the entrapment zone, no more
than 6" (15 cm) above the fl oor for a door and no more than 27.5" (69.6 cm) above grade for a gate. Minimum
installation width of 5 feet and maximum width of 50 feet. The devices can either be installed on the left or right
of the entrapment zone.
The brackets must be securely fastened to a solid surface such as the wall framing. If installing in masonry
construction, add a piece of wood at each location to avoid drilling extra holes in masonry if repositioning is
necessary.
The invisible light beam path must be unobstructed. No part of the gate or door (or door tracks, springs,
hinges, rollers or other hardware) may interrupt the beam while the door/gate is closing.

To prevent possible SERIOUS INJURY or DEATH from a closing door or gate:
• Be sure to DISCONNECT POWER to the operator BEFORE installing the photoelectric sensor.
• The door or gate 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 beam NO HIGHER than 6" (15 cm) above the fl oor for door and
27.5" (69.8 cm) above grade for gate operators.
• LiftMaster
®
Monitored Entrapment Protection devices are for use with LiftMaster
®
Commercial Door
and Gate Operators ONLY. Use with ANY other product voids the warranty.
• Entrapment protection devices MUST be installed per the operator owner's manual for each Entrapment
Zone.

WIRING CONNECTIONS
Be sure power to the operator is disconnected. Do not run control wiring in the same conduit
with AC power.
The wire cable is intended to aid in installation to either a junction box on the wall or can be routed through
the control station mounted next to the door allowing the wires to run in the same conduit as the controls. The
photoelectric sensor also is capable of receiving a 1/2" thread conduit.
Connect the photoelectric sensor as illustrated below for your operator type. The wiring is polarity sensitive so
make certain to wire as indicated below.

TROUBLESHOOTING
REPLACEMENT PARTS LIST
ALIGN THE PHOTOELECTRIC SENSOR AND REFLECTOR
TEST THE LIFTMASTER MONITORED PROTECTOR SYSTEM
The photoelectric sensor and refl ector must be aligned with the same orientation. When properly wired and
aligned the amber LED within the photoelectric sensor will not be illuminated. The alignment LED within the
photoelectric sensor will blink rapidly when the eye is not at the optimal positioning. If the LED is solidly
illuminated this indicates it is powered up properly and is not aligned with the refl ector.
Commercial door installations:
The photoelectric sensor works on the close cycle on a LiftMaster commercial door operator only. With
the door in the full open position place an obstruction in the path of the photoelectric sensor and then try a
CLOSE command. The operator should not move. Now remove the obstruction and give the operator a close
command. The door should close and when the path of the photoelectric sensor is obstructed the door should
reverse.
Gate installations:
The photoelectric sensor can be installed to work on either the open or closing cycles. Refer to the gate
operator installation manual for more information.
