CAUTION
WARNING
To avoid damage to the garage door and
opener, disable locks before installing and
operating the opener. Use a wood screw or nail
to hold locks in the “open” (unlocked) position.
Operation at other than 120V 60 Hz will cause
opener malfunction and damage.
An unbalanced garage door might not reverse
when required and someone under the door
could be seriously injured or killed.
If your garage door binds, sticks or is out of
balance, call for professional garage door
service. Garage doors, door springs, cables,
pulleys, brackets and their hardware, are
under extreme tension and can cause serious
injury or death. Do not try to loosen, move or
adjust them yourself!
Ropes left on a garage door could cause
someone to become entangled and killed.
Remove all ropes connected to the door before
installing and operating the opener.
Test your Door
Before you begin, complete the following test to
make sure your door is balanced, and is not
sticking or binding:
• Lift the door about halfway as shown. Release the
door. It should stay in place, supported entirely by
its springs.
• Raise and lower the door to see if there is any
binding or sticking.
Identify the type and height of your door, any special
conditions that exist, and any additional materials that
may be required, by referring to page 4.

Installation Step 1
WARNING
Determine Header Bracket Location
If the header bracket is not rigidly fastened to
a structural support on the header wall or
ceiling, the safety reverse system may not
work properly (see page 26). The door might
not reverse when required, and could cause
serious injury or death.
The garage door springs, cables, pulleys,
brackets and their hardware are under extreme
tension. Do not attempt to loosen, move or
adjust them yourself. Serious personal injury
or death could result. Call for professional
garage door service.
Installation procedures vary according to garage
door types. Follow the instructions which apply to
your door.

bracket to structural supports before installing the
opener. The bracket and fastening hardware are not
supplied.
• Measure the distance from each side of the opener
to the structural support.
• Cut both pieces of the hanging bracket to required
lengths.
• Drill 3/16" pilot holes in the structural supports.
• Attach one end of each bracket to a support with
5/16"x1-7/8" lag screws.
• Fasten the opener to the hanging brackets with
5/16"-18x7/8" hex screws, lock washers and nuts.
• Check to make sure the T-rail is centered over the
door (or in line with the header bracket if the
bracket is not centered above the door).

WARNING
Installation Step 6
Install the Door Control
Children operating or playing with a garage
door opener can injure themselves or others.
The garage door could close and cause serious
injury or death.
Install the Door Control (or any additional push
buttons) out of the reach of children and away
from all moving parts of the door and door
hardware, but where the garage door is visible.
Do not allow children to operate the push
button or the remote control transmitters.
A moving garage door could injure someone
under it. Activate the opener only when the
door is properly adjusted, you can see it clearly,
and there are no obstructions to door travel.
• Strip 1/4" of insulation from one end of the bell
wire; connect the wire to the two screw terminals
on the back of the Door Control by color:
white to 2, and white/red to 1.
• Locate the Door Control within sight of the
door at a minimum height of 5 feet where small
children cannot reach, and away from all
moving parts of the door and door hardware.
Fasten the Lighted Door Comtrol Button securely
with 6ABx1-1/2" screws. If installing into drywall,
drill 5/32" holes and use the anchors provided.
• Run the bell wire up the wall and across the ceiling
to the opener. Use insulated staples to secure the
wire in several places. Be careful not to pierce the
wire with a staple, thereby resulting in a short.
• Receiver terminal screws and the antenna are
located on the back panel of the opener. Position
the antenna wire as shown.
• Then connect the bell wire to the opener terminal
screws: white to 2 and white/red to 1.
• Remember to affix the User Safety Instruction
label to the wall near the Door Control, and the
Maintenance Instruction label in a prominent
location on the inside of the garage door.
If the label adhesive will not adhere to your garage
wall surface (or becomes loose with time) use tacks
to secure the label alongside the Door Control.
Page 28 explains how to operate the opener using
the door control.
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.

WARNING
Attach the Manual Release
Rope and Handle
Do not use the red handle to pull the door
open or closed. The rope knot could become
untied and you could fall. Use the manual
release only to disengage the trolley and, if
possible, only when the door is closed.
Garage doors are heavy. If the door is open
when the handle is pulled, the door could
close inadvertently if it is not properly
balanced. Serious injury may result to persons
under the door. Make sure the doorway is clear
of persons and obstructions before pulling
handle when the door is open.
Overhand
Knot
Trolley
• Thread one end of the rope through the hole in the
top of the red handle so "NOTICE" reads right side

IMPORTANT INFORMATION ABOUT THE SAFETY
REVERSING SENSOR
WARNING
Without a properly working safety reversing
sensor, persons (particularly children) could be
injured or killed by a closing garage door. Read
and follow all instructions.
To protect small children, install the safety
reversing sensor so that the beam will be no
higher than 4"-6" above the garage floor.
Disconnect power to the garage door opener
before installing 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.
When properly connected and aligned, the safety
reversing sensor will detect an obstacle in the path of
its electronic beam. The sending eye (with an orange
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 door control will flash for 5 seconds.
The units must be installed inside the garage so that
the sending and receiving eyes face each other
across the door, between 4 – 6" 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.

MOUNTING AND WIRING THE SAFETY SENSORS
• 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. See Figure 5.
• Finger tighten the wing nuts.
• Run the wires from both sensors to the opener. Use
insulated staples to secure wire to wall and ceiling.
• Strip 1/4" of insulation from each set of wires.
Separate white and white/black wires sufficiently to
connect to the opener terminal screws: white to 2
and white/black to 3.

TROUBLESHOOTING THE SAFETY 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 screw terminal
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 door control will blink 10 times. See page 17.
ALIGNING THE SAFETY 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 orange 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.

CAUTION
Fasten Door Bracket
To prevent damage to steel, aluminum,
fiberglass or glass panel doors, always
reinforce the inside of the door both vertically
and horizontally with angle iron.
Follow instructions which apply to your door type
as illustrated below or on page 21.
A horizontal brace should be long enough to be secured to 2 vertical supports. A vertical brace should
cover the height of the top panel.
The illustration 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.

Adjustment Procedures for One-Piece Doors
Open Door Adjustment:
Decrease UP limit
• Turn the UP limit adjustment screw counterclockwise 5-1/2 turns.
• Press the Door Control button. The trolley will
travel to the fully open position.
• Manually raise the door to the open position
(parallel to the floor), and lift the door arm to the
trolley. The arm should touch the trolley just in
back of the door arm connector hole. Refer to the
fully open trolley/door arm positions in the
illustration. If the arm does not extend far enough,
adjust the limit further. One full turn equals 2" of
trolley travel.
Closed Door Adjustment:
Decrease DOWN limit
• Turn the DOWN limit adjustment screw clockwise
5 complete turns.
• Press the Door Control button. The trolley will travel
to the fully closed position.
• Manually close the door and lift the door arm to the
trolley. The arm should touch the trolley just ahead
of the door arm connector hole. Refer to the fully
closed trolley/door arm positions in the illustration. If
the arm is behind the connector hole, adjust the
limit further. One full turn equals 2" of trolley travel.
Connect the door arm to the trolley.
• Close the door and join the curved arm to the connector hole in the trolley with the remaining clevis pin. It may
be necessary to lift the door slightly to make the connection.
• Secure with a ring fastener.
• Run the opener through a complete travel cycle. If the door has a slight "backward" slant in full open position
as shown in the illustration, decrease the UP limit until the door is parallel to the floor.
23
Adjustment Section: Pages 24 – 26
Adjustment Step 1
WARNING
Adjust the UP and DOWN Limits
Do not make any limit adjustments until the
Safety Reversing Sensors are completely
installed.
Improper adjustment of the travel limits will
interfere with the proper operation of the
safety reverse system. The door might not
reverse when required and could seriously
injure or kill someone under it. Test the safety
reverse system following all adjustments to
the travel limits. See page 26.
Limit adjustment settings regulate the points at
which the door will stop when moving up or down.
The door will stop in the up direction if anything
interferes with door travel. The door will reverse in
the down direction if anything interferes with the
door travel (including binding or unbalanced doors).
To operate the opener, press the Door Control
button. Run the opener through a complete travel
cycle.
• Does the door open and close completely?
• Does the door stay closed and not reverse
unintentionally when fully closed?
If your door passes both of these tests, no limit
adjustments are necessary unless the reversing test
fails (see page 26).

Adjustment
Screws
Adjustment Label
How and When to Adjust the Limits
• If the door does not open completely, but
opens at least five feet:
Increase up travel. Turn the UP limit adjustment
screw clockwise. One turn equals 2" of travel.
NOTE: To prevent the trolley from hitting the
cover protection bolt, keep a minimum distance
of 2-4" between the trolley and the bolt.
If you have adjusted the door arm to the maximum
length and the door still will not close completely,
lower the header bracket. See Installation Step 1,
pages 8 and 9.
• If the opener reverses in fully closed position:
Decrease down travel. Turn the DOWN limit
adjustment screw clockwise. One turn equals 2" of
travel.
• If door does not open at least 5 feet:
Adjust the UP (open) force as explained in
Adjustment Step 2.
• If the door reverses when closing and there is
no visible interference to travel cycle:
If the opener lights are flashing, the Safety Reversing
Sensors are either not installed, misaligned, or
obstructed. See Troubleshooting, page 19.
Test the door for binding: Pull the manual release
handle. Manually open and close the door. If the door
is binding, call for garage door service. If the door is
not binding or unbalanced, adjust the DOWN (close)
force. See Adjustment Step 2.
• If the door does not close completely:
Increase down travel. Turn the DOWN limit
adjustment screw counterclockwise. One turn
equals 2" of travel.
If the door still won't close completely and the trolley
bumps into the pulley bracket (see page 4), try
lengthening the door arm (see page 22).
24
Adjustment Step 2
WARNING
Adjust the Force
Too much force on the door will interfere with
the proper operation of the safety reverse
system. The door might not reverse properly
when required and could seriously injure or
kill someone under it. Do not increase the
force beyond the minimum required to close
the door. Do not use the force adjustments to
compensate for a binding or sticking garage
door. Test the safety reverse system following
all adjustments to force levels. See page 26.
Force adjustment controls are located on the back
panel of the opener. Force adjustment settings
regulate the amount of power required to open and
close the door.
The door will stop in the up direction if anything
interferes with its travel. The door will reverse in the
down direction if anything interferes with its travel
(including binding or unbalanced doors).
If the forces are set too light, door travel may be
interrupted by nuisance reversals in the down
direction and stops in the up direction. Weather
conditions can affect the door movement, so
occasional adjustment may be needed.
The maximum force adjustment range is
260 degrees, about 3/4 of a complete turn. Do not
force controls beyond that point. Turn force
adjustment controls with a screwdriver.

How and When to Adjust the Forces
If the door doesn't open at least 5 feet:
Increase UP (Open) force by turning the control
clockwise. Make 10 degree turn adjustments until
door opens completely. Re-adjust the UP limit if
necessary. After each adjustment, run the opener
through a complete travel cycle.
Test the DOWN (close) force:
Grasp the door bottom when the door is about
halfway through DOWN (close) travel. The door
should reverse. Reversal halfway through down
travel does not guarantee reversal on a one inch
obstruction. See page 26. If the door is hard to
hold or doesn't reverse, decrease the DOWN (close)
force by turning the control counterclockwise.
Make 10 degree turn adjustments until the door
reverses normally. After each adjustment, run the
opener through a complete cycle.
If the door reverses during the down (close) cycle
and the opener light isn't flashing:
Increase DOWN (close) force by turning the control
clockwise. Make 10 degree turn adjustments until the
door completes a close cycle. After each adjustment,
run the opener through a complete travel cycle.
Do not increase the force beyond the minimum
amount required to close the door.
Test the UP (open) force:
Grasp the door bottom when the door is about
halfway through UP (open) travel. The door should
stop. If the door is hard to hold or doesn't stop,
decrease UP (open) force by turning the control
counterclockwise.
Make 10 degree turn adjustments until the door
stops easily. After each adjustment, run the opener
through a complete travel cycle.

1. If open, the door will close. If closed, it will open.
2. If closing, the door will reverse.
3. If opening, the door will stop (allowing space for
entry and exit of pets and for fresh air).
4. If the door has been stopped in a partially open
position, it will close.
5. If obstructed while closing, the door will reverse.
6. If obstructed while opening, the door will stop.
7. The garage door will reverse in the closing cycle,
and the opener light will blink for 5 seconds, when
the invisible beam is broken. If fully open, the door
will not close when the beam is broken. The sensor
has no effect in the opening cycle.
If the sensor is not installed, or is not aligned correctly,
the door won't close from any remote control
transmitter. However, you can close the door with the
Door Control, the Outside Keylock, or Keyless Entry, if
you activate them until down travel is complete. If you
release them too soon, the door will reverse.
The Opener Light will turn on under the following
conditions: When the opener is initially plugged in;
when the power is interrupted; when the opener is
activated. It will turn off automatically after 4-1/2
minutes or provide constant light when the Light

Receiver and Remote Control Programming
NOTICE: To comply with FCC/IC rules, adjustment or modification of this receiver
and/or transmitter are prohibited, except for changing the code setting or replacing the
transmitter battery. THERE ARE NO OTHER USER SERVICEABLE PARTS.
Your garage door opener receiver and remote control
transmitter have been set at the factory to a matching
code. The door will open when you press the remote
control push button. The code between the remote
control and the receiver changes with each use,
randomly accessing over 100 billion new codes.
Your SECURITY✚ opener will operate with:
• several SECURITY✚ remote controls (with yellow
indicator lights) utilizing up to 8 functions.
• one Keyless Entry System (with SECURITY✚ logo)
Follow the instructions below to program your opener
to match any additional remotes you may purchase.
See Accessories on page 34.
WARNING
Children operating or playing with a garage
door opener can injure themselves or others.
The garage door could close and cause
serious injury or death. Do not allow children
to operate the door control(s) or remote
control transmitter(s).
A moving garage door could injure or kill
someone under it. Activate the opener only
when you can see the door clearly, it is free of
obstructions, and is properly adjusted.
To Add A Remote Control
1. Press and hold the remote control push button.
See Figure 1.
2. Then press and release the “Smart” (learn) button
on the back panel of the opener in Figure 2. The
indicator light on the panel will begin to blink and the
opener light will flash once.
3. Release the remote push button.
Now the opener will operate when that remote control
button is pressed. Test it by pressing the remote
button to see that the door goes up and down.
If you release the remote control push button
before the opener light flashes, the opener will not
accept the code.

Having a Problem?
Situation
Probable Cause & Solution
The opener doesn't
operate from either
the door control or
the remote control:
1. Does the opener have electric power? Plug a lamp into the outlet. If it doesn't light,
check the fuse box or the circuit breaker. (Some outlets are controlled by a wall switch.)
2. Have you disabled all door locks? Review installation instruction warnings on
Page 7.
3. Is there a build-up of ice or snow under the door? The door may be frozen to the
ground. Remove any restriction.
4. The garage door spring may be broken. Have it replaced.
5. Repeated operation may have tripped the overload protector in the motor. Wait
15 minutes. Try again.
Opener operates from 1. Is the door control push bar lit? If not, Remove the bell wire from the opener terminal
remote control, but
screws. Short the red and white terminals by touching both terminals at the same
not from door control:
time with a piece of wire. If the opener runs, check for a faulty wire connection at the
door control, a short under the staples, or a broken wire.
2. Are the wiring connections correct? Review Step 6, page 14.
The door operates
from the door control,
but not from the
remote control:
1. Is the door push bar flashing? If your model has the Multi-Function “Lock feature”,
turn it off.
2. Your opener needs to re-learn a remote control code. Refer to instructions on the
opener panel.
3. Program the receiver to match the remote control code.
4. Repeat the receiver programming procedure with all remote controls.
The remote control
has short range:
1. Change the location of the remote control in your car.
2. Check to be sure the antenna on the side or back panel of the opener extends fully
downward.
3. Some installations may have shorter range due to a metal door, foil backed
insulation, or metal garage siding.
Opener noise is
disturbing in living
quarters of home:
If operational noise is a problem because of proximity of the opener to the living
quarters, the Vibration Isolator Kit 41A3263 can be installed. This kit was designed to
minimize vibration to the house and is easy to install.
The garage door
opens and closes
by itself:
1. Be sure that all remote control push buttons are off.
2. Remove the bell wire from the door control terminals and operate from the remote
control only. If this solves the problem, the door control is faulty (replace), or there is
an intermittent short on the wire between the door control and the opener.
3. Clear memory and reprogram all remote controls.
The door doesn't
open completely:
1. If the door has been working properly but now doesn't open all the way, increase the
up force. See page 25.
2. Is something obstructing the door? Remove the obstruction or repair the door.
3. If door opens at least 5 feet, the travel limits may need to be increased. One turn
equals 2 inches of travel. See page 24.
Repeat the safety reverse test after the adjustment is complete.
The door stops but
doesn't close
completely:
Review the travel limits adjustment procedures on page 24.
Repeat the safety reverse test after any adjustment of door arm length, close
force or down limit.
30
Having a Problem? (continued)
Situation
Probable Cause & Solution
The door opens but
won't close:
1. If the opener light blinks, check the safety reversing sensor. See page 19.
2. If the opener light does not blink and it is a new installation, check the down force.
See Adjustment Step 2, page 25. For an existing installation, see below.
Repeat the safety reverse test after the adjustment is complete.
The door reverses for
no apparent reason
and opener light
doesn't blink:
1. Is something obstructing the door? Pull the manual release handle. Operate the door
manually. If it is unbalanced or binding, call for professional garage door service.
2. Clear any ice or snow from the garage floor area where the door closes.
3. Review the force adjustment procedures on page 25.
4. If door reverses in the fully closed position, decrease the travel limits (page 24).
Repeat safety reverse test after adjustments to force or travel limits. The need
for occasional adjustment of the force and limit settings is normal. Weather
conditions in particular can affect door travel.
The door reverses for
no apparent reason
and opener lights
blink for 5 seconds
after reversing:
Check the safety reversing sensor. Remove any obstruction or align the receiving eye.
See page 19.
The opener light:
. . . doesn't turn on:
Replace the light bulbs (75 watts maximum). Use a standard neck garage door opener
bulb if regular bulb burns out.
. . . doesn't turn off:
Is the Light feature on? Turn it off.
The opener strains or
maximum force is
needed to operate
door:
The door may be out of balance or the springs are broken. Close the door and use the
manual release to disconnect the trolley. Open and close the door manually. A properly
balanced door will stay in any point of travel while being supported entirely by its springs. If
it does not, disconnect the opener and call a professional garage door serviceman. Do not
increase the force to operate the opener.
The opener motor
hums briefly, then
won't work:
1. The garage door springs are broken. See above.
2. If the problem occurs on the first operation of the opener, door may be locked. Disable
the door lock. If the chain was removed and reinstalled, the motor may be out of phase.
Remove the chain; cycle the motor to the down position. Observe the drive sprocket.
When it turns in a clockwise direction and stops in the down position, reinstall the chain.
Repeat the safety reverse test after the adjustment is complete.
The opener won't
operate due to
power failure:
1. Use the manual release to disconnect the trolley. The door can be opened and closed
manually. When the power is restored, press the Door Control push bar and trolley will
automatically reconnect (unless trolley is in lockout position.) See page 28.
2. The Outside Quick Release accessory (for use on garages with no service door)
disconnects the trolley from outside the garage in case of power failure.
The chain droops
or sags:
It is normal for the chain to droop slightly in the closed door position. Use the manual
release rope and handle to disconnect the trolley. If the chain returns to the normal
height when the trolley is disengaged and the door reverses on a 2x4 laid flat, no
adjustments are needed. (See page 7.)
