IMPORTANT INFORMATION ABOUT THE SAFETY REVERSING SENSORS
The safety reversing sensors must be connected and aligned correctly before the garage door opener will
move in the down direction.
The safety reversing sensors can be attached to the door track, the wall, or the floor. The sensors should be no more
than 6" (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.

Wall Installation

Position sensor brackets (P) on wall. Make sure safety reversing sensors are no more than 6" (15 cm) above the floor
and the light beam is unobstructed. Mark and drill 3/16" pilot holes. Attach with lag screws (not provided). NOTE: If
additional clearance is needed, wood blocks or extension brackets (not provided) can be used.

Floor Installation

Measure distance "X" to position both sensor brackets the same distance from the wall. Make sure the light beam is
unobstructed. Attach sensor brackets (P) to the floor using concrete anchors (not provided).
