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, and the opener lights will fl ash 10 times.
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 fl oor. 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 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.
