INSTALLINGTHE BRACKETS
Be sure power to the openeris 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 doortrack installation (preferred):
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.
Waft installation (Figure 2 & 3):
Placethe bracket against the wall with curved arms facing the
door. Besure there is enough clearancefor the sensor beam to
be unobstructed.
If additional depth is needed,an extension bracket
(see Accessories) or wood blocks can be used.
Use bracket mounting holes as a template to locate and drill
(2) 3/16" diameter pilot holes on the wall at eachside of the
door, no higher than 6" (15 cm) above the floor.
Attach brackets to wall with lag screws (not provided).
If using extension brackets or wood blocks, adjust right and
left assembliesto the same distance out from the mounting
surface. Make sure all door hardware obstructions are cleared.

elevatesensor brackets so the lenseswill be no higher than
6" (15 cm) abovethe floor.
