Preparing your garage door  
Before you begin:  
To prevent possible SERIOUS INJURY or DEATH:  
Disable locks.  
• ALWAYS call a trained door systems technician if  
garage door binds, sticks, or is out of balance. An  
unbalanced garage door may NOT reverse when  
required.  
Remove any ropes connected to garage door.  
Complete the following test to make sure your garage  
door is balanced and is not sticking or binding:  
1. Lift the door about halfway as shown. Release the  
door. If balanced, it should stay in place, supported  
entirely by its springs.  
• NEVER try to loosen, move or adjust garage door,  
door springs, cables, pulleys, brackets or their  
hardware, ALL of which are under EXTREME tension.  
• Disable ALL locks and remove ALL ropes connected  
to garage door BEFORE installing and operating  
garage door opener to avoid entanglement.  
2. Raise and lower the door to see if there is any  
binding or sticking.  
If your door binds, sticks, or is out of balance, call a  
trained door systems technician.  
To prevent damage to garage door and opener:  
• ALWAYS disable locks BEFORE installing and  
operating the opener.  
• ONLY operate garage door opener at 120V, 60 Hz to  
avoid malfunction and damage.

INSTALLATION STEP 4  
®
Install The Protector System  
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:  
The safety reversing sensor must be connected and  
aligned correctly before the garage door opener will  
move in the down direction.  
• Correctly connect and align the safety reversing  
sensor. This required safety device MUST NOT be  
disabled.  
IMPORTANT INFORMATION ABOUT  
THE SAFETY REVERSING SENSOR  
• Install the safety reversing sensor so beam is NO  
HIGHER than 6" (15 cm) above garage floor.  
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.

DOOR TRACK MOUNT (RIGHT SIDE)  
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:  
Door

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.

INSTALLATION STEP 6  
Hang the Opener  
To avoid possible SERIOUS INJURY from a falling  
garage door opener, fasten it SECURELY to structural  
supports of the garage. Concrete anchors MUST be  
used if installing ANY brackets into masonry.  
Three representative installations are shown. Yours may  
be different. Hanging brackets should be angled  
(Figure 1) to provide rigid support. On finished ceilings  
(Figure 2 and Figure 3), attach a sturdy metal bracket  
to structural supports before installing the opener. This  
bracket and fastening hardware are not provided.

INSTALLATION STEP 7  
Install the Door Control  
Locate door control within sight of the door at a minimum  
height of 5 feet (1.5 m) where small children cannot  
reach, and away from moving parts of the 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 indicator  
light behind the cover will indicate proper connection. If not  
lit, the Lock and Light features will not function (reverse  
wires to correct).  
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.  
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 2 and white/red wire

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.  
DO NOT use short neck or specialty light bulbs.  
DO NOT use halogen bulbs. Use ONLY  
incandescent.  
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.  
To prevent damage to the opener:  
DO NOT use bulbs larger than 100W.  
ONLY use A19 size bulbs.  
Reverse the procedure to close the lens.  
Use A19, standard neck garage door opener bulbs for  
replacement.

Attach the Emergency Release Rope  
and Handle  
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.  
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. 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.

INSTALLATION STEP 10  
Electrical Requirements  
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.  
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.

TROUBLESHOOTING THE SAFETY  
REVERSING SENSORS  
INSTALLATION STEP 11  
Complete Safety Reversing Sensor  
Installation  
1. If the sending eye indicator light does not glow steadily  
after installation, check for:  
• Electric power to the opener.  
ALIGNING THE SAFETY REVERSING SENSORS  
• A short in the white or white/black wires. These can  
occur at staples, or at opener connections.  
Plug in the opener. The indicator lights in both the  
sending and receiving eyes will glow steadily if wiring  
connections and alignment are correct.  
• Incorrect wiring between sensors and opener.  
• A broken wire.  
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.  
2. If the sending eye indicator light glows steadily but the  
receiving eye indicator light doesn’t:  
• Check alignment.  
Loosen the sending eye wing nut and readjust, aiming  
directly at the receiving eye. Lock in place.  
• Check for an open wire to the receiving eye.  
3. If the receiving eye indicator light is dim, realign either  
sensor.  
Loosen the receiving eye wing nut and adjust the  
sensor vertically and/or horizontally until it receives the  
sender’s beam. When the green indicator light glows  
steadily, tighten the wing nut.  
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. (If bulbs are not installed, 10  
clicks can be heard.) See page 11.

INSTALLATION STEP 12  
Fasten the Door Bracket  
Fiberglass, aluminum or lightweight steel garage doors  
WILL REQUIRE reinforcement BEFORE installation  
of door bracket. 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.  
Header  
Bracket  
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.

- Turn the UP limit adjustment screw  
counterclockwise 4 turns.  
- 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" (5 cm) of trolley travel.  
- Press the Door Control push 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" (5 cm) of trolley  
travel.  
3. 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.  
• Closed door adjustment: decrease DOWN travel  
limit  
• 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.  
- Turn the DOWN limit adjustment screw clockwise  
4 complete turns.  
- Press the Door Control push button. The trolley will  
travel to the fully closed position.  
NOTE: When setting the up limit on the following page, the  
door should not have a "backward" slant when fully open  
as illustrated below. A slight backward slant will cause  
unnecessary bucking and/or jerking operation as the door  
is being opened or closed from the fully open position.

ADJUSTMENT STEP 1  
Adjust the UP and DOWN Travel Limits  
Without a properly installed safety reversal system,  
persons (particularly small children) could be  
SERIOUSLY INJURED or KILLED by a closing garage  
door.  
• Incorrect adjustment of garage door travel limits  
will interfere with proper operation of safety reversal  
system.  
Limit adjustment settings regulate the points at which the  
door will stop when moving up or down.  
To operate the opener, press the Door Control push bar.  
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 one control (force or travel limits) is adjusted, the  
other control may also need adjustment.  
• After ANY adjustments are made, the safety reversal  
system MUST be tested. Door MUST reverse on  
contact with 1-1/2" (3.8 cm) high object (or 2x4 laid  
flat) on floor.  
If your door passes both of these tests, no limit  
adjustments are necessary unless the reversing test fails  
(Adjustment Step 3, page 25).  
Adjustment procedures are outlined below. Read the  
procedures carefully before proceeding to Adjustment  
Step 2. Use a screwdriver to make limit adjustments. Run  
the opener through a complete travel cycle after each  
adjustment.  
NOTE: Repeated operation of the opener during  
adjustment procedures may cause the motor to overheat  
and shut off. Simply wait 15 minutes and try again.  
To prevent damage to vehicles, be sure fully open  
door provides adequate clearance.  
NOTE: If anything interferes with the door’s upward  
travel, it will stop. If anything interferes with the door’s  
downward travel (including binding or unbalanced doors),  
it will reverse.  
HOW AND WHEN TO ADJUST THE LIMITS  
If the door does not open completely but opens at  
least 5 feet (1.5 m):  
Limit Adjustment Screws  
Left Side Panel  
Increase up travel. Turn the UP limit adjustment screw  
clockwise. One turn equals 2" (5 cm) of travel.  
NOTE: To prevent the trolley from hitting the cover  
protection bolt, keep a minimum distance of 2-4"  
(5-10 m) between the trolley and the bolt.  
If door does not open at least 5 feet (1.5 m):  
Adjust the UP (open) force as explained in Adjustment  
Step 2.  
If the door does not close completely:  
Increase down travel. Turn the down limit adjustment  
screw counterclockwise. One turn equals 2" (5 cm) of  
travel.  
ADJUSTMENT LABEL  
If the door reverses when closing and there is no  
visible interference to travel cycle:  
If door still won’t close completely and the trolley  
bumps into the pulley bracket (page 4), try lengthening  
the door arm (page 21) and decreasing the down limit.  
If the opener lights are flashing, the Safety Reversing  
Sensors are either not installed, misaligned, or  
obstructed. See Troubleshooting, page 18.  
If the opener reverses in fully closed position:  
Decrease down travel. Turn the down limit adjustment  
screw clockwise. One turn equals 2" (5 cm) of travel.  
Test the door for binding: Pull the emergency release  
handle. Manually open and close the door. If the  
door is binding or unbalanced, call for a trained  
door systems technician. If the door is balanced and  
not binding, adjust the DOWN (close) force. See  
Adjustment Step 2.

ADJUSTMENT STEP 2  
Adjust the Force  
Without a properly installed safety reversal system,  
persons (particularly small children) could be  
SERIOUSLY INJURED or KILLED by a closing garage  
door.  
• Too much force on garage door will interfere with  
proper operation of safety reversal system.  
• NEVER increase force beyond minimum amount  
required to close garage door.  
• NEVER use force adjustments to compensate for a  
binding or sticking garage door.  
• If one control (force or travel limits) is adjusted, the  
other control may also need adjustment.  
• After ANY adjustments are made, the safety reversal  
system MUST be tested. Door MUST reverse on  
contact with 1-1/2" (3.8 cm) high object (or 2x4 laid  
flat) on floor.  
Force adjustment controls are located on the back panel  
of the motor unit. Force adjustment settings regulate the  
amount of power required to open and close the door.  
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 about 3/4 of a  
complete turn. Do not force controls beyond that point.  
Turn force adjustment controls with a screwdriver.  
NOTE: If anything interferes with the door’s upward  
travel, it will stop. If anything interferes with the door’s  
downward travel (including binding or unbalanced doors),  
it will reverse.  
HOW AND WHEN TO ADJUST THE FORCES  
Force  
Adjustment  
Controls  
1. 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 1-1/2" (3.8 cm) obstruction.  
See Adjustment Step 3, page 25. If the door is hard to  
hold or doesn’t reverse, DECREASE the DOWN (close)  
force by turning the control counterclockwise. Make  
small adjustments until the door reverses normally.  
After each adjustment, run the opener through a  
complete cycle.  
Back Panel  
If the door reverses during the down (close) cycle  
and the opener lights aren’t flashing, Increase DOWN  
(close) force by turning the control clockwise. Make  
small 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.  
Antenna  
2. Test the UP (open) force  
FORCE ADJUSTMENT LABEL  
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 small adjustments until the door stops easily  
and opens fully. After each adjustment, run the opener  
through a complete travel cycle.  
Open Force  
Close Force  
If the door doesn’t open at least 5 feet (1.5 m),  
Increase UP (open) force by turning the control  
clockwise. Make small adjustments until door opens  
completely. Readjust the UP limit if necessary. After  
each adjustment, run the opener through a complete  
travel cycle.

door.  
• Safety reversal system MUST be tested every  
month.  
With the door fully open, place a 1-1/2" (3.8 cm) board  
(or a 2x4 laid flat) on the floor, centered under the  
garage door.  
• If one control (force or travel limits) is adjusted, the  
other control may also need adjustment.  
Operate the door in the down direction. The door must  
reverse on striking the obstruction.  
• After ANY adjustments are made, the safety reversal  
system MUST be tested. Door MUST reverse on  
contact with 1-1/2" high (3.8 cm) object (or 2x4 laid  
flat) on the floor.  
ADJUST  
If the door stops on the obstruction, it is not traveling  
far enough in the down direction. Increase the DOWN  
limit by turning the DOWN limit adjustment screw  
counterclockwise 1/4 turn.  
NOTE: On a sectional door, make sure limit  
adjustments do not force the door arm beyond a  
straight up and down position. See the illustration on  
page 21.  
Repeat the test.  
When the door reverses on the 1-1/2" (3.8 cm) board,  
remove the obstruction and run the opener through 3  
or 4 complete travel cycles to test adjustment.  
IMPORTANT SAFETY CHECK:  
Test the Safety Reverse System after:  
Each adjustment of door arm length, limits, or force  
controls.  
Any repair to or adjustment of the garage door  
(including springs and hardware).  
Any repair to or buckling of the garage floor.  
Any repair to or adjustment of the opener.

Test the Protector System  
Without a properly installed safety reversing sensor,  
persons (particularly small children) could be  
SERIOUSLY INJURED or KILLED by a closing garage  
door.  
Press the remote control push button to open the door.  
Place the opener carton in the path of the door.  
Press the remote control push button to close the  
door. The door will not move more than an inch  
(2.5 cm), and the opener lights will flash.  
The garage door opener will not close from a remote if the  
indicator light in either sensor is off (alerting you to the  
fact that the sensor is misaligned or obstructed).  
If the opener closes the door when the safety reversing  
sensor is obstructed (and the sensors are no more  
than 6" (15 cm) above the floor), call for a trained door  
systems technician.

IMPORTANT SAFETY INSTRUCTIONS  
WARNING  
To reduce the risk of SEVERE INJURY or DEATH:  
1. READ AND FOLLOW ALL WARNINGS  
AND INSTRUCTIONS.  
9. If one control (force or travel limits) is adjusted, the  
other control may also need adjustment.  
2. ALWAYS keep remote controls out of reach of  
children. NEVER permit children to operate or play  
with garage door control push buttons or remote  
controls.  
3. ONLY activate garage door when it can be seen  
clearly, it is properly adjusted, and there are no  
obstructions to door travel.  
10. After ANY adjustments are made, the safety reversal  
system MUST be tested.  
11. Safety reversal system MUST be tested every  
month. Garage door MUST reverse on contact with  
1-1/2" (3.8 cm) high object (or a 2x4 laid flat) on  
the floor. Failure to adjust the garage door opener  
properly may cause SEVERE INJURY or DEATH.  
4. ALWAYS keep garage door in sight until completely  
closed. NO ONE SHOULD CROSS THE PATH OF THE  
MOVING DOOR.  
5. NO ONE SHOULD GO UNDER A STOPPED,  
PARTIALLY OPEN DOOR.  
6. 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, causing SEVERE INJURY  
or DEATH.  
12. ALWAYS KEEP GARAGE DOOR PROPERLY  
BALANCED (see page 3). An improperly balanced  
door may NOT reverse when required and could  
result in SEVERE INJURY or DEATH.  
13. ALL repairs to cables, spring assemblies and  
other hardware, ALL of which are under EXTREME  
tension, MUST be made by a trained door systems  
technician.  
14. ALWAYS disconnect electric power to garage door  
opener BEFORE making ANY repairs or removing  
covers.  
7. NEVER use emergency release handle unless garage  
doorway is clear of persons and obstructions.  
8. NEVER use handle to pull garage door open or  
closed. If rope knot becomes untied, you could fall.  
15.  
SAVE THESE  
INSTRUCTIONS.  
6. If obstructed while opening, the door will stop.  
7. 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 misaligned, the door  
won’t close from a hand-held remote. 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.  
Using Your Garage Door Opener  
Your Security® opener and hand-held remote control  
have been factory-set to a matching code which changes  
with each use, randomly accessing over 100 billion  
new codes. Your opener will operate with up to eight  
Security® remote controls and one Security® Keyless  
Entry System. If you purchase a new remote, or if you  
wish to deactivate any remote, follow the instructions in  
the Programming section.  
The opener lights will turn on under the following  
conditions: when the opener is initially plugged in; when  
power is restored after interruption; when the opener is  
activated.  
Activate your opener with any of the following:

the light button for 10 seconds, until the light goes on,  
then off again. To restore this feature, start with the  
opener lights on, then press and hold the light button for  
10 seconds until the light goes off, then on again.  
When the opener is activated (with the safety reversing  
sensor correctly installed and aligned)  
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.  
4. If the door has been stopped in a partially open  
position, it will close.  
5. If obstructed while closing, the door will reverse. If the  
obstruction interrupts the sensor beam, the opener  
lights will blink for five seconds.
