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 fl oor. They may be installed in one of
three ways, as follows.
Garage door track 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
fl ush, 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):
• 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.
• 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
each side of the door, no higher than 6" (15 cm) above
the fl oor.
• Attach brackets to wall with lag screws (not provided).
• 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):
• 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 fl oor.
• Carefully measure and place right and left assemblies
at the same distance out from the wall. Be sure all door
hardware obstructions are cleared.
• Fasten to the fl oor with concrete anchors as shown.
