INSTALLATION STEP 1
Determine the Header Bracket Location
Installation procedures vary according to garage door
types. Follow the instructions which apply to your door.
1. Close the door and mark the inside vertical centerline
of the garage door.
2. Extend the line onto the header wall above the door.
You can fasten the header bracket within 4 feet
(1.22 m) of the left or right of the door center only if
a torsion spring or center bearing plate is in the way;
or you can attach it to the ceiling (see page 9) when
clearance is minimal. (It may be mounted on the
wall upside down if necessary, to gain approximately
1/2" (1 cm).)
If you need to install the header bracket on a 2x4
(on wall or ceiling), use lag screws (not provided)
to securely fasten the 2x4 to structural supports as
shown here and on page 9.
3. Open your door to the highest point of travel as shown.
Draw an intersecting horizontal line on the header wall
above the high point:
• 2" (5 cm) above the high point for sectional door
and one-piece door with track.
• 8" (20 cm) above the high point for one-piece door
without track.
This height will provide travel clearance for the top
edge of the door.
NOTE: If the total number of inches exceeds the height
available in your garage, use the maximum height
possible, or refer to page 9 for ceiling installation.
To prevent possible SERIOUS INJURY or DEATH:
• Header bracket MUST be RIGIDLY fastened to
structural support on header wall or ceiling,
otherwise garage door might NOT reverse when
required. DO NOT install header bracket over drywall.
• Concrete anchors MUST be used if mounting header
bracket or 2x4 into masonry.
• NEVER try to loosen, move or adjust garage door,
springs, cables, pulleys, brackets, or their hardware,
ALL of which are under EXTREME tension.
• ALWAYS call a trained door systems technician if
garage door binds, sticks, or is out of balance. An
unbalanced garage door might NOT reverse when
required.

To prevent possible SERIOUS INJURY or DEATH from
electrocution:
• Be sure power is NOT connected BEFORE installing
door control.
• Connect ONLY to 24 VOLT low voltage wires.
To prevent possible SERIOUS INJURY or DEATH from a
closing garage door:
• Install door control within sight of garage door,
out of reach of children at a minimum height of 5 feet
(1.5 m), and away from ALL moving parts of door.
• NEVER permit children to operate or play with door
control push buttons or remote control transmitters.
• Activate door ONLY when it can be seen clearly, is
properly adjusted, and there are no obstructions to
door travel.
• ALWAYS keep garage door in sight until completely
closed. NEVER permit anyone to cross path of closing
garage door.
INSTALLATION STEP 6
Install the Door Control
Locate door control within sight of door at a minimum
height of 5 feet (1.5 m) where small children cannot
reach, and away from moving parts of door and door
hardware. The installation surface must be smooth and
flat. If installing into drywall (Figure 1), drill 5/32" holes
and use anchors provided. For pre-wired installations
(as in new home construction), it may be mounted to
a single gang box (Figure 2). NOTE: After installation,
a green or amber indicator light behind the cover will
indicate proper connection. If not lit, the Lock and Light
features will not function (reverse wires to correct).
1. Strip 7/16" (11 mm) of insulation from one end of bell
wire and connect to the two screw terminals on back
of door control by color: white wire to WHT and
white/red wire to the RED (Figure 3).
2. Remove cover by gently prying at slot at the top of the
cover with a small flat head screwdriver (Figure 4).
Fasten with 6ABx1-1/4" self-tapping screws (drywall
installation) or 6-32x1" machine screws (into gang
box) as follows:
• Drill and install bottom screw, allowing 1/8" (3 mm)
to protrude above wall surface.
• Position bottom of door control on screw head and
slide down to secure. Adjust screw for snug fit.
• Install top screw with care to avoid cracking plastic
housing. DO NOT overtighten.
• Insert bottom tabs and snap on cover.
NOTE: The push bar may stick if the door control is not
mounted on a smooth surface. If a click is not heard
when pressing the push bar, loosen the two mounting
screws or relocate the door control to a smoother
surface.
3. (Standard installation only) Run bell wire up wall and
across ceiling to motor unit. Use insulated staples to
secure wire in several places. DO NOT pierce wire with
a staple, creating a short or open circuit.
4. Strip 7/16" (11 mm) of insulation from end of bell wire.
Connect bell wire to the quick-connect terminals as
follows: white to white and white/red to red (Figure 5).
NOTE: When connecting multiple door controls to the
opener, twist same color wires together. Insert wires
into quick-connect holes: white to white and red/white
to red.
5. Use tacks or staples to permanently attach entrapment
warning label to wall near door control, and manual
release/safety reverse test label in a prominent location
on inside of garage door.
NOTE: DO NOT connect the power and operate the opener
at this time. The trolley will travel to the full open position
but will not return to the close position until the sensor
beam is connected and properly aligned. See Safety
Reversing Sensor Instructions beginning on page 16.

INSTALLATION STEP 7
Install the Light
• Press the release tabs on both sides of lens. Gently
rotate lens back and downward until the lens hinge is
in the fully open position. Do not remove the lens.
• Install a 100 watt maximum light bulb in each socket.
Light bulb size should be A19, standard neck only.
The lights will turn ON and remain lit for approximately
4-1/2 minutes when power is connected. Then the
lights will turn OFF.
• Reverse the procedure to close the lens.
• Use A19, standard neck garage door opener bulbs for
replacement.
NOTE: Use only standard light bulbs. The use of short
neck or speciality light bulbs may overheat the endpanel
or light socket.
INSTALLATION STEP 8
Attach the Emergency Release Rope and
Handle
• Thread one end of the rope through the hole in the
top of the red handle so “NOTICE” reads right side up
as shown. Secure with an overhand knot at least
1" (2.5 cm) from the end of the rope to prevent
slipping.
• Thread the other end of the rope through the hole in
the release arm of the outer trolley.
• Adjust rope length so the handle is 6 feet (1.83 m)
above the floor. Ensure that the rope and handle clear
the tops of all vehicles to avoid entanglement. Secure
with an overhand knot.
NOTE: If it is necessary to cut the rope, heat seal the cut
end with a match or lighter to prevent unraveling.
To prevent possible OVERHEATING of the endpanel or
light socket:
• DO NOT use short neck or specialty light bulbs.
• DO NOT use halogen bulbs. Use ONLY incandescent.
To prevent damage to the opener:
• DO NOT use bulbs larger than 100W.
• ONLY use A19 size bulbs.
To prevent possible SERIOUS INJURY or DEATH from
a falling garage door:
• If possible, use emergency release handle to
disengage trolley ONLY when garage door is
CLOSED. Weak or broken springs or unbalanced
door could result in an open door falling rapidly and/
or unexpectedly.
• NEVER use emergency release handle unless garage
doorway is clear of persons and obstructions.
• NEVER use handle to pull door open or closed. If
rope knot becomes untied, you could fall.

INSTALLATION STEP 9
Electrical Requirements
To avoid installation difficulties, do not run the opener
at this time.
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.
If permanent wiring is required by your local code, refer
to the following procedure.
To make a permanent connection through the 7/8" hole in
the top of the motor unit:
• Remove the motor unit cover screws and set the cover
aside.
• Remove the attached 3-prong cord.
• Connect the black (line) wire to the screw on the brass
terminal; the white (neutral) wire to the screw on
the silver terminal; and the ground wire to the green
ground screw. The opener must be grounded.
• Reinstall the cover.
To avoid installation difficulties, do not run the opener
at this time.
To prevent possible SERIOUS INJURY or DEATH from
electrocution or fire:
• Be sure power is NOT connected to the opener, and
disconnect power to circuit BEFORE removing cover
to establish permanent wiring connection.
• Garage door installation and wiring MUST be in
compliance with ALL local electrical and building
codes.
• NEVER use an extension cord, 2-wire adapter, or
change plug in ANY way to make it fit outlet. Be sure
the opener is grounded.

INSTALLATION STEP 10
Install The Protector System®
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.
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 mounting brackets are designed to clip onto the track
of sectional garage doors without additional hardware.
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 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.
Be sure power is NOT connected to the garage door
opener BEFORE installing the safety reversing sensor.
To prevent SERIOUS INJURY or DEATH from 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.

INSTALLING THE BRACKETS
Be sure power to the opener is disconnected. Install
and align the brackets so the sensors will face each other
across the garage door, with the beam no higher than
6" (15 cm) above the floor. They may be installed in one of
three ways, as follows.
Garage door track installation (preferred):
• Slip the curved arms over the rounded edge of each
door track, with the curved arms facing the door. Snap
into place against the side of the track. It should lie
flush, with the lip hugging the back edge of the track,
as shown in Figure 1.
If your door track will not support the bracket securely,
wall installation is recommended.
Wall installation (Figures 2 & 3):
• Place the bracket against the wall with curved arms
facing the door. Be sure there is enough clearance for
the sensor beam to be unobstructed.
• If additional depth is needed, an extension bracket (see
Accessories) or wood blocks can be used.
• Use bracket mounting holes as a template to locate
and drill (2) 3/16" diameter pilot holes on the wall at
each side of the door, no higher than 6" (15 cm) above
the floor.
• Attach brackets to wall with lag screws (not provided).
• If using extension brackets or wood blocks, adjust
right and left assemblies to the same distance out from
the mounting surface. Make sure all door hardware
obstructions are cleared.
Floor installation (Figure 4):
• Use wood blocks or extension brackets (see
Accessories) to elevate sensor brackets so the lenses
will be no higher than 6" (15 cm) above the floor.
• Carefully measure and place right and left assemblies
at the same distance out from the wall. Be sure all door
hardware obstructions are cleared.
• Fasten to the floor with concrete anchors as shown.

MOUNTING AND WIRING THE SAFETY
REVERSING SENSORS
Mounting:
• Slide a 1/4"-20x1/2" carriage bolt head into the slot
on each sensor. Use wing nuts to fasten sensors
to brackets, with lenses pointing toward each other
across the door. Be sure the lens is not obstructed by a
bracket extension (Figure 5).
• Finger tighten the wing nuts.
Option A - Installation Without Pre-Wiring:
• Run the bell wire from both sensors to the garage
door opener. Attach the wire to the wall and ceiling
with the staples (Figure 6).
Option B - Pre-Wired Installation:
If your garage already has wires installed for the safety
reversing sensors, follow the instructions below:
• Cut the end of the safety reversing sensor wire, making
sure there is enough wire to reach the pre-installed
wires from the wall (Figure 7).
• Separate the safety reversing sensor wires and strip
7/16" (11 mm) of insulation from each end. Choose two
of the pre-installed wires and strip 7/16" (11 mm) of
insulation from each end. Make sure that you choose
the same color pre-installed wires for each sensor
(Figure 8).
• Connect the pre-installed wires to the sensor wires with
wire nuts making sure the colors correspond for each
sensor (Figure 9).

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.
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.
• 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.
TROUBLESHOOTING THE SAFETY
REVERSING SENSORS
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.
2. If the sending eye indicator light glows steadily but the
receiving eye indicator light doesn’t:
• Check alignment.
• 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, it will not close. The opener
lights will blink 10 times. See page 16.
Connect to garage door opener:
• 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 10).

Fiberglass, aluminum or lightweight steel garage
doors WILL REQUIRE reinforcement BEFORE
installation of door bracket. Contact your door
manufacturer for reinforcement kit.
INSTALLATION STEP 11
Fasten the Door Bracket
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 12.
SECTIONAL DOORS
1. Center the door bracket on the previously marked
vertical centerline used for the header bracket
installation. Note correct UP placement, as stamped
inside the bracket.
2. Position the top edge of the bracket 2"-4" (5-10 cm)
below the top edge of the door, OR directly below any
structural support across the top of the door.
3. Mark, drill holes and install as follows, depending on
your door’s construction:
Metal or light weight doors using a vertical angle iron
brace between the door panel support and the door
bracket:
• Drill 3/16" fastening holes. Secure the door bracket
using the two 1/4"-14x5/8" self-threading screws
(Figure 2A).
• Alternately, use two 5/16" bolts, lock washers and nuts
(not provided) (Figure 2B).
Metal, insulated or light weight factory reinforced doors:
• Drill 3/16" fastening holes. Secure the door bracket
using the self-threading screws (Figure 3).
Wood Doors:
• Use top and bottom or side to side door bracket holes.
Drill 5/16" holes through the door and secure bracket
with 5/16"x2" carriage bolts, lock washers and nuts
(not provided) (Figure 4).
NOTE: The 1/4"-14x5/8" self-threading screws are not
intended for use on wood doors.
