The safety reversing sensors can be attached to the door track, the wall, or the floor. If the door track will
not support the sensor bracket a wall installation is recommended. Choose one of the following
installations.
OPTION A
DOOR TRACK INSTALLATION
1. Slide the curved arms of the sensor bracket around the edge of the door track. Snap into place
so that the sensor bracket is flush against the track.
2. Slide the carriage bolt into the slot on each sensor.
3. Insert the bolt through the hole in the sensor bracket and attach with the wing nut. The lenses
on both sensors should point toward each other. Make sure the lens is not obstructed by the
sensor bracket.

OPTION B
WALL INSTALLATION
If additional clearance is needed an extension bracket (not provided) or wood blocks can be used. Make
sure each bracket has the same amount of clearance so they will align correctly.
1. Position the sensor bracket against the wall with the curved arms facing the door. Make sure
there is enough clearance for the beam to be unobstructed. Mark holes.
2. Drill 3/16 inch pilot holes for each sensor bracket and attach the sensor brackets to the wall
using lag screws (not provided).
3. Slide the carriage bolt into the slot on each sensor.
4. Insert the bolt through the hole in the sensor bracket and attach with the wing nut. The lenses
on both sensors should point toward each other. Make sure the lens is not obstructed by the
sensor bracket.
