Planning
Do you have an access door in addition to the garage
door? If not, Model 7702CB Emergency Key Release
is required. See Accessories page.

Identify the type and height of your garage door. Survey
your garage area to see if any of the conditions below
apply to your installation. Additional materials may be
required. You may find it helpful to refer back to this
page and the accompanying illustrations as you proceed
with the installation of your opener.

Look at the garage door where it meets the floor. Any
gap between the floor and the bottom of the door must
not exceed 1/4" (6 mm). Otherwise, the safety reversal
system may not work properly. See Adjustment Step 3.
Floor or door should be repaired.

Depending on your requirements, there are several
installation steps which may call for materials or
hardware not included in the carton.
• Installation Step 1 - Look at the wall or ceiling above
the garage door. The header bracket must be securely
fastened to structural supports.
• Installation Step 5 - Do you have a finished ceiling in
your garage? If so, a support bracket and additional
fastening hardware may be required.
• Installation Step 11 - Depending upon garage
construction, extension brackets or wood blocks may
be needed to install sensors.
• Installation Step 11 - Alternate floor mounting of the
safety reversing sensor will require hardware not
provided.

SECTIONAL DOOR INSTALLATIONS
• Do you have a steel, aluminum, fiberglass or glass
panel door? If so, horizontal and vertical reinforcement
is required (Installation Step 12).
• The opener should be installed above the center of the
door. If there is a torsion spring or center bearing plate
in the way of the header bracket, it may be installed
within 4 feet (1.2 m) to the left or right of the door
center. See Installation Steps 1 and 12.
• If your door is more than 7 feet (2.1 m) high, see rail
extension kits listed on Accessories page.

Without a properly working safety reversal system, persons
(particularly small children) could be SERIOUSLYINJURED
or KILLED by a closing garage door.
• The gap between the bottom of the garage door and the
floor MUST NOTexceed 1/4" (6 mm). Otherwise, the safety
reversal system may not work properly.
• The floor or the garage door MUST be repaired to eliminate
the gap.

• Generally, a one-piece door does not require
reinforcement. If your door is lightweight, refer to the
information relating to sectional doors in Installation
Step 12.
• Depending on your door's construction, you may need
additional mounting hardware for the door bracket
(Step 12).

Requirements
To prevent possible SERIOUSINJURYor DEATHfrom
electrocution or fire:

To avoid installation difficulties, do not run the
opener at this time.

• Disconnect ALL electric and battery power BEFORE
performing ANY service or maintenance.
• Garage door installation and wiring MUST be in compliance
with ALL local electrical and building codes.
• NEVERuse an extension cord, 2-wire adapter, or change
plug in ANY way to make it fit outlet. Be sure the opener
is grounded.

To reduce the risk of electric shock, your garage door
opener has a grounding type plug with a third grounding
pin. This plug will only fit into a grounding type outlet. If
the plug doesn't fit into the outlet you have, contact a
qualified electrician to install the proper outlet.

Be sure power is not connected to the garage door opener
BEFOREinstalling the safety reversing sensor.
To prevent SERIOUSINJURY or DEATHfrom a closing
garage door:
• Correctly connect and align the safety reversing sensor.
This required safety device MUST NOT be disabled.
• Install the safety reversing sensor so beam is NO HIGHER
than 6" (15 cm) above garage floor.

The safety reversing sensor must be connected and
aligned correctly before the garage door opener will
move in the down direction.
IMPORTANT INFORMATION ABOUT
THE SAFETY REVERSING SENSOR
When properly connected and aligned, the sensor will
detect an obstacle in the path of its electronic beam. The
sending eye (with an amber indicator light) transmits an
invisible light beam to the receiving eye (with a green
indicator light). If an obstruction breaks the light beam
while the door is closing, the door will stop and reverse
to full open position, and the opener lights will flash
10 times.

If it is necessary to mount the units on the wall, the
brackets must be securely fastened to a solid surface
such as the wall framing. Extension brackets (see
accessories) are available if needed. If installing in
masonry construction, add a piece of wood at each
location to avoid drilling extra holes in masonry if
repositioning is necessary.

The units must be installed inside the garage so that the
sending and receiving eyes face each other across the
door, no more than 6" (15 cm) above the floor. Either can
be installed on the left or right of the door as long as the
sun never shines directly into the receiving eye lens.

The invisible light beam path must be unobstructed. No
part of the garage door (or door tracks, springs, hinges,
rollers or other hardware) may interrupt the beam while
the door is closing.

The mounting brackets are designed to clip onto the
track of sectional garage doors without additional
hardware.

Facing the door from inside the garage.

• Finger tighten the wing nuts.
• Run the wires from both sensors to the opener. Use
insulated staples to secure wire to wall and ceiling.

TROUBLESHOOTING
THE SAFETY
REVERSING SENSORS

• Strip 7/16" (11 mm) of insulation from each set of
wires. Separate white and white/black wires sufficiently
to connect to the opener quick-connect terminals.
Twist like colored wires together. Insert wires into
quick-connect holes: white to white and white/black
to grey (Figure 6).

1. If the sending eye indicator light does not glow steadily
after installation, check for:
• Electric power to the opener.
• A short in the white or white/black wires. These can
occur at staples, or at opener connections.
• Incorrect wiring between sensors and opener.
• A broken wire.

ALIGNING THE SAFETY REVERSING SENSORS
• Plug in the opener. The indicator lights in both the
sending and receiving eyes will glow steadily if wiring
connections and alignment are correct.

2. If the sending eye indicator light glows steadily but the
receiving eye indicator light doesn't:
• Check alignment.

The sending eye amber indicator light will glow
regardless of alignment or obstruction. If the green
indicator light in the receiving eye is off, dim, or flickering
(and the invisible light beam path is not obstructed),
alignment is required.

• Check for an open wire to the receiving eye.
3. If the receiving eye indicator light is dim, realign either
sensor.
NOTE: When the invisible beam path is obstructed or
misaligned while the door is closing, the door will
reverse. If the door is already open, # will not close. The
opener lights will blink 10 times. See page 21.

• Loosen the sending eye wing nut and readjust, aiming
directly at the receiving eye. Lock in place.
• Loosen the receiving eye wing nut and adjust sensor
until it receives the sender's beam. When the green
indicator light glows steadily, tighten the wing nut.

Contact your door manufacturer for reinforcement kit.

Follow instructions which apply to your door type
as illustrated below or on the following page.
A horizontal reinforcement
brace should be long
enough to be secured to two or three vertical
supports. A vertical reinforcement brace should
cover the height of the top panel.
Figure 1 shows one piece of angle iron as the horizontal
brace. For the vertical brace, 2 pieces of angle iron are
used to create a U-shaped support. The best solution is
to check with your garage door manufacturer for an
opener installation door reinforcement kit.
NOTE: Many door reinforcement kits provide for direct
attachment of the clevis pin and door arm. In this case
you will not need the door bracket; proceed to Step 13.
