Installation Step 10

Install the Safety Reversing Sensor

(Receiving and Sending Eyes)
Figures 2, 3 and 4 show recommended assembly of
bracket(s) and "C" wrap based on the wall installation
of the sensors on each side of the garage door as
shown on page 16, or on the garage door tracks
themselves.
Figure 5 shows variations which may fit your
installation requirements better. Make sure the wraps
and brackets are aligned so the sensors will face
each other across the garage door.
• Fasten the "C" wraps to the mounting brackets
having square holes, using the hardware shown in
Figure 2.
WALL INSTALLATION ONLY
• Connect each assembly to a slotted bracket, using
the hardware shown in Figure 3. Note alignment of
brackets for left and right sides of the door.
• Finger tighten the lock nuts.
• Use bracket mounting holes as a template to locate
and drill (2) 3/16" diameter pilot holes on both sides of
the garage door, 4"-6" above the floor (but not
exceeding 6"). See Warning on page 16.
• Attach bracket assemblies with 1/4"x1-1/2" lag
screws as shown in Figure 3.
• Adjust right and left side bracket assemblies to the
same distance out from mounting surface. Make sure
all door hardware obstructions are cleared. Tighten
the nuts securely.
DOOR TRACK INSTALLATION ONLY
• Discard slotted bracket. Drill 3/8" holes in each track
and fasten securely with hardware as shown in
Figure 4. See Warning on page 16 regarding height
of sensor beam.
