Install the Protector System

The safety reversing sensor must be connected and aligned correctly
before the garage door will move in the down direction. This is a required
safety device and cannot be disabled.
IMPORTANT INFORMATION ABOUT THE SAFETY REVERSING SENSOR
When properly connected and aligned, the safety reversing sensor will detect
an obstacle in the path of its electronic beam. The sending sensor (with an
amber indicator light) transmits an invisible light beam to the receiving sensor
(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.
The sensors must be installed inside the garage so that the sending and
receiving sensors face each other across the door, no more than 6 inches
(15 cm) above the floor. Either sensor 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 mounting brackets are designed to clip onto the track of sectional garage
doors without additional hardware.
If it is necessary to mount the sensors 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 (door tracks, springs, hinges, rollers or other hardware) may interrupt the
beam while the door is closing.
