The Protector System®  
IMPORTANT INFORMATION ABOUT THE  
SAFETY REVERSING SENSOR  
WARNING  
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.  
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.  
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 opener light will flash for 5 seconds.  
Disconnect power to the garage door opener before  
installing the safety reversing sensor.  
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, 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 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  
garage door track without additional hardware.

WARNING  
Install the Door Control and  
Connect all Wiring  
DO NOT CONNECT TO LIVE ELECTRICAL WIRING. CONNECT  
ONLY TO 24 VOLT LOW VOLTAGE WIRES. CONNECTION TO  
LIVE WIRES OR HIGHER VOLTAGE MAY CAUSE SERIOUS  
INJURY FROM SHOCK, BURN OR ELECTROCUTION.  
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.  
The door control is typically attached directly to the wall. If  
installing into drywall, drill 5/32" holes and use the anchors  
provided. For pre-wired installations (as in new home  
construction), the multi-function door control can be mounted  
to a standard single gang box.  
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 push button or the remote control transmitter.  
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.

Installation Step 8  
Electrical Requirements  
WARNING  
To prevent electrocution or fire, installation and wiring  
must be in compliance with local electrical and building  
codes.  
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.  
Do NOT use an extension cord, 2-wire adapter, or change  
the plug in any way to make it fit your outlet.  
If the plug doesn't fit into the outlet you have, contact a  
qualified electrician to install the proper outlet.  
To avoid installation difficulties,  
do not run the opener until Step 9 below.  
If permanent wiring is required by your local code,  
refer to the following procedure:

connections and alignment are correct.  
• Incorrect wiring between sensors and opener.  
• A broken wire.  
2. If the sending eye indicator light glows steadily but  
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.  
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.  
• Loosen the sending eye wing nut and re-adjust, aiming  
directly at the receiving eye. Lock in place.  
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 flash 10 times. (If bulbs are not  
installed, 10 clicks are audible.) See page 12.  
• Loosen the receiving eye wing nut and adjust sensor  
vertically and/or horizontally until it receives the  
sender’s beam. When the green indicator light glows  
steadily, tighten the wing nut.

Installation Step 12  
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 an 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 Step 1  
Adjust the UP and DOWN Limits  
Do not make any limit adjustments until the safety  
reversing sensors are completely installed.  
WARNING  
Improper adjustment of the travel limits 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. Test the safety  
reverse system monthly, and 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 push bar or  
button. Run the opener through a complete travel cycle.

How and When to Adjust the Limits  
If the door does not open completely but opens at least  
five feet:  
If the opener reverses in fully closed position:  
Decrease down travel. Turn the DOWN limit adjustment  
screw clockwise. One turn equals 2" of travel.  
Increase up travel. Turn the UP limit adjustment screw  
clockwise. One turn equals 2" of travel.  
If the door reverses when closing and there is no  
visible interference to travel cycle:  
If door does not open at least 5 feet: Adjust the UP  
(open) force as explained in Adjustment Step 2.  
If the opener lights are flashing, the Safety Reversing  
Sensors are either not installed, misaligned, or obstructed.  
See Troubleshooting, page 18.  
If the door does not close completely:  
Increase down travel. Turn the DOWN limit adjustment  
screw counterclockwise. One turn equals 2" of travel.  
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 door still won't close completely, try lengthening the  
door arm. (Page 22.)  
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 8/9.

Adjustment Step 2  
Adjust the Force  
WARNING  
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 amount 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 monthly, and following all adjustments to force  
levels. See page 26.  
Force adjustment controls are located on the right 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 about 3/4 of a  
complete turn. Do not force controls beyond that point.

How and When to Adjust the Forces  
Test the DOWN (close) force  
If the door doesn't open at least 5 feet:  
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.  
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.  
If the door reverses during the down (close) cycle and  
the opener lights aren't flashing:  
Make small adjustments until the door reverses normally.  
After each adjustment, run the opener through a complete  
cycle.  
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.  
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 small adjustments until the door stops easily. After  
each adjustment, run the opener through a complete  
travel cycle.

Test the Safety Reverse System  
WARNING  
Failure to test and adjust the safety reverse system may  
result in serious injury or death to persons trapped by a  
closing garage door. Repeat this test once a month and  
adjust as needed.  
Test  
• Place a one-inch board (or a 2x4 laid flat) on the floor,  
centered under the garage door.  
• Operate the door in the down direction. The door must  
reverse on striking the obstruction.

IMPORTANT SAFETY INSTRUCTIONS  
WARNING  
WARNING  
To reduce the risk of severe injury or death to persons:  
1. READ AND FOLLOW ALL INSTRUCTIONS.  
2. Do not permit children either to operate or to play with the opener. Keep remote control in a location  
inaccessible to children.  
3. Operate opener only when the door is in full view and free from any obstruction. Keep the door in sight  
until it is completely closed. NO ONE SHOULD CROSS THE PATH OF THE MOVING DOOR.  
4. Check safety reversal system monthly. See page 26. The garage door MUST reverse on contact with a one  
inch object (or a 2x4 board laid flat) placed on the floor. If an adjustment is made to one of the controls  
(either force or limits of travel), the other control may need to be adjusted also, and the safety reversal  
system must be checked. Failure to properly adjust the opener may result in severe injury or death.  
5. If possible, use the manual release only when the door is in a closed position. Caution should be taken  
whenever the disconnect cord is actuated with the door open. Weak or broken springs may cause the door to  
fall rapidly, causing injury or death to persons.  
6. KEEP GARAGE DOORS PROPERLY BALANCED. See page 3. An improperly balanced door may not  
reverse when required, and could result in severe injury or death. Repairs to cables, spring assemblies and  
other hardware must be made by a professional garage door person.  
7. Disconnect the electric power to the garage door opener before making any repairs or removing the covers.

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.

the remote control, but  
not from the door  
control:  
1. Is the door control push bar lit? If not, Remove the bell wire from the opener terminal  
screws. Short the red and white terminals by touching both terminals at the same 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 Installation Step 7, page 17.

control:  
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 right side panel of opener extends fully.  
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.
