The Safety Reversing Sensor
Information you'll need before you begin the installation of the safety reversing sensor
The safety reversing sensor must be connected and
aligned correctly before the garage door opener will
move in the down direction. This is a required safety
device and cannot be disabled.
Installation procedures are the same Jbr sectional and
one-piece doot_'.
Be sure power to the opener is disconnected.
The sending eye transmits an invisible light beam to the
receiving eye. The units can be installed on either side of
the garage door as long as the snn never shines directly
into the receiving eye lens.
Look at the label on the connector end of each case to
identify the sensors.
The brackets must be comaected and fastened so that the
sending and receiving eyes face each other as shown.
If an obstrnction breaks the light beam while the garage
door is closing, the door will stop and reverse to full open
position and the opener lights will flash for 5 seconds.
The brackets must be secnrely fastened to a solid surt:ace
snch as the studs on either side of the door, or add a piece
of wood at each location if installing in masonry
construction.
Without aproperly working safety reversing sensor,
persons(particularlychildren)couldbe injuredor killed
by aclosing garage door. Read and follow all
instructions.
To protectsmall children, install the safety reversing
sensor so that the beamwill be no higherthan 4"-6"
abovethegaragefloor.
Disconnect power to the garage door opener before
installingthesafetyreversingsensor.
The invisible light beam path must be unobstrncted. No
part of the garage door (or door tracks, springs, hinges,
rollers or other hardware) can interrupt the beam while
the door is closing. If it does, use a piece of wood to bnild
om each sensor lnounting location m the lninilnnm depth
required for light beam clearance.

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.
