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 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.
