INSTALLING THE BRACKETS
Be sure power to the opener is disconnected. Install and align
the brackets so the sensors will face each other across the garage
door, with the beam no higher than 6" (15 cm) above the floor.
They may be installed in one of three ways, as follows.
Garage door track installation (preferred):
1. Slip the curved arms over the rounded edge of each door
track, with the curved arms facing the door. Snap into
place against the side of the track. It should lie flush, with
the lip hugging the back edge of the track, as shown in
Figure 1.
If your door track will not support the bracket securely, wall
installation is recommended.
Wall installation (Figures 2 and 3):
1. Place the bracket against the wall with curved arms facing
the door. Be sure there is enough clearance for the sensor
beam to be unobstructed.
2. If additional depth is needed, an extension bracket (see
Accessories) or wood blocks can be used.
3. Use bracket mounting holes as a template to locate and
drill (2) 3/16" diameter pilot holes on the wall at each side
of the door, no higher than 6" (15 cm) above the floor.
4. Attach brackets to wall with lag screws (not provided).
5. If using extension brackets or wood blocks, adjust right
and left assemblies to the same distance out from the
mounting surface. Make sure all door hardware
obstructions are cleared.
Floor installation (Figure 4):
1. Use wood blocks or extension brackets (see Accessories)
to elevate sensor brackets so the lenses will be no higher
than 6" (15 cm) above the floor.
2. Carefully measure and place right and left assemblies at
the same distance out from the wall. Be sure all door
hardware obstructions are cleared.
3. Fasten to the floor with concrete anchors as shown.
