Installation
STEP 13 Install the Protector System
®
Be sure power is NOT connected to the garage door opener BEFORE installing the safety reversing
sensor.
To prevent SERIOUS INJURY or DEATH from closing garage door:
l
Correctly connect and align the safety reversing sensor. This required safety device MUST NOT
be disabled.
l
Install the safety reversing sensor so beam is NO HIGHER than 6" (15 cm) above garage floor.
The safety reversing sensors must be connected and aligned correctly before the garage door
opener will move in the down direction.
IMPORTANT INFORMATION ABOUT THE SAFETY REVERSING SENSORS
When properly connected and aligned, the sensor will detect an obstacle in the path of its electronic
beam. The sending eye (with an amber indicator light) transmits an invisible light beam to the receiving
eye (with a green\ indicator light). 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. The units must
be installed inside the garage so that the sending and receiving eyes face each other across the door, no
more than 6" (15 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 eye lens. The mounting brackets are designed to clip onto the
track of sectional garage doors without additional hardware.
If it is necessary to mount the units on the wall, the brackets must be securely fastened to a solid surface
such as the wall framing. Extension brackets (see accessories) are available if needed. 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 garage door (or door tracks, springs,
hinges, rollers or other hardware) may interrupt the beam while the door is closing.

The safety reversing sensors can be attached to the door track, the wall, or the floor. The sensors should
be no more than 6 inches (15 cm) above the floor. If the door track will not support the sensor bracket a
wall installation is recommended. Choose one of the following installations.
OPTION A
DOOR TRACK INSTALLATION
1. Slide the curved arms of the sensor bracket around the edge of the door track. Snap into place
so that the sensor bracket is flush against the track.
2. Slide the carriage bolt into the slot on each sensor.
3. Insert the bolt through the hole in the sensor bracket and attach with the wing nut. The lenses on
both sensors should point toward each other. Make sure the lens is not obstructed by the sensor
bracket.
