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 19, or on the
garage door tracks themselves.
For Garage Wall or Door Track Installation
• Fasten the "C" wraps to the mounting brackets
having square holes, using the hardware shown
in Figure 2.
For Door Track Installation Only
• Discard slotted bracket. Drill 3/8" holes in each
track and fasten securely with hardware as shown
in Figure 3.
For Wall Installation
• Connect each assembly to a slotted bracket, using
the hardware shown in Figure 4. 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 19.)
• Attach bracket assemblies with 1/4"x1-1/2"
lag screws as shown in Figure 4.
• 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.
Figures 5 and 6 are 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.
