IMPORTANT INFORMATION ABOUT THE PHOTOELECTRIC SENSORS
Be sure power to the operator is disconnected.
When properly connected and aligned, the photoelectric sensors will detect an obstruction in the path of its invisible light beam. If an
obstruction breaks the light beam while the door is closing, the door will stop and typically reverse to the full open position.
The photoelectric sensors must be installed inside the garage so that the sending and receiving sensors face each other across the door,
no more than 6" (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 eye lens. This product is not suitable for outdoor use.
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 garage door (or door tracks, springs, hinges, rollers or other
hardware) may interrupt the beam while the door is closing. If it does, use a piece of wood to build out each sensor mounting location to
the minimum depth required for light beam clearance.
