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 & 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.
