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 from 
4 – 6" above the floor.

They may be installed in one of three ways, depending
on your requirements (see illustration and follow
instructions below):

1. (Preferred) Clipped onto the left and right garage door

tracks. See Figure 1.

2. Fastened to the wall on each side of the garage.

See Figure 2.

3. Fastened to the floor (see Figure 3). Concrete anchors

and wood blocks or extension brackets will be needed.

Garage door track installation:

• Slip the curved arms over the rounded edge of the door

track. 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.

If your door track will not support the bracket securely,
wall installation is recommended.

Wall installation: 

• Place the bracket against the wall and make 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, from 4–6" above the floor. (See
warning at beginning of Installation Step 10.)

• 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: 

• Use wood blocks or extension brackets (see

Accessories) to elevate sensor brackets so the lenses
will be 4-6" above the floor. 

• 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 floor with concrete anchors as shown.
