Installation Step 4
Install the Safety Reversing Sensor
(Receiving and Sending Eyes)
Figures 1 and 2 show assembly of brackets and "C" wrap
based on the recolrdnended installation of the sensors on
each side of the garage door as shown on page 16.
However, Figures 3 and 4 are variations which may fit
your installation requirelnents better. Make sure the
wraps and brackets are aligned so the sensors will
face each other across the garage door.
1. Fasten the "C" wraps to the mounting brackets having
square holes, using the hardware shown in Figure 3.
2. Connect each assembly to a slotted bracket, using the
hardware shown in Figure 2.
Note the alignment of the brackets for left and
right sides of the door.
3. Finger tighten the lock nuts.
4. 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.)
5. Attach bracket assemblies with 1/4"x1-1/2" lag screws
as shown in Figure 2.
6. Adjust right and left side bracket assemblies to the
same distance out from the lnounting surface. Make
sure all door hardware obstructions are cleared.
Tighten the nuts securely.
