Determine the Header Bracket Location

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.

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 13) 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 13.

3. Open your door to the highest point of travel as shown. Draw an inter secting 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 13 for ceiling installation.

Locate door control within sight of door, at a minimum height of 5 feet (1.5 m) where small children cannot reach, away from moving parts of door and door hardware. If installing into drywall, drill 5/32" holes and use the anchors provided. For pre-wired installations (as in new home construction), it may be mounted to a single gang box (Figure 2).

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 to the 1.

2. Remove cover by gently prying at slot in top of the cover with a small flat head screwdriver. Fasten with 6ABx1-1/4" self-tapping screws (drywall installation) or 6-32x1" machine screws (into gang box) as follows:

• 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.

• Drill and install top screw with care to avoid cracking

plastic housing. Do not overtighten.

• Insert top tabs and snap on cover.

3. (For 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.

5. Position the antenna wire as shown.

6. 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 power and operate 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.

To prevent possible SERIOUS INJURY or DEATH from electrocution:

• Disconnect ALL electric and battery power BEFORE performing ANY service or maintenance.

• 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 controls.

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" (2 cm) 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:

• 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.

• 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 11

Invisible Light Beam Protection Area

Safety Reversing Sensor 6" (15 cm) max. above floor

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.

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.

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.

Facing the door from inside the garage.

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 (Figure 1).

If your door track will not support the bracket securely, wall installation is recommended.

Wall installation (Figures 2 and 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

• 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.

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

• 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).

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.

Figure 5

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 21.

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.

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.

Travel limits regulate the points at which the door will stop when moving up or down. Follow the steps below to set the limits.

Figure 1

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.

• NEVER use force adjustments to compensate for a binding or sticking garage door.

• After ANY adjustments are made, the safety reversal system MUST be tested. Door MUST reverse on contact with 1-1/2"vd(3.8 cm) high object (or 2x4 laid flat) on floor.

To program the travel limits:

Adjust the position of the door by using the black and purple buttons. Black moves the door UP (open) and purple moves the door DOWN (close).

1. Setting the UP position: Press and hold the black button until the yellow indicator light starts flashing slowly then release.

2. Push and hold the black button until the door reaches the desired UP (open) position (Figure 2).

NOTE: Check to be sure the door opens high enough for your vehicle.

3. Push the remote control or door control (Figure 3). This sets the UP (open) limit and begins closing the door.

4. Immediately when the door begins to move down, press and release either the black or purple button. This will stop the door.

5. Setting the DOWN position: Push and hold the purple button until the door reaches the desired DOWN (closed) position (Figure 4).

6. Once the door is closed, if there appears to have too much pressure on the door, you may toggle the door back and forth using the black and purple buttons to reach the desired closed position.

7. Push the remote control or the door control (Figure 3). This sets the DOWN (close) limit and should bring the door to the open position.

• If the opener is not stopping exactly where you would like it, repeat steps 1 through 7 and program the limits again.

• When the unit stops in both the desired up (open) and down (close) positions, proceed to

Adjustment Step 2, Setting the Force.

To prevent damage to vehicles, be sure fully open door provides adequate clearance.

Setting the Force

The force setting button is located on the left panel of the motor unit. The force setting measures the amount of force required to open and close the door.

1. Locate the purple button on the left panel of the motor unit (Figure 1).

2. Push the purple button twice to enter the opener into Force Adjustment Mode (Figure 1). The LED (Indicator Light) will flash quickly.

3. Push the remote control or door control (Figure 2). The door will travel to the DOWN (close) position. Push the remote control or control console again, the door will travel to the UP (open) position. Push the remote control or door control a third time to send the door to the DOWN (close) position.

The LED (Indicator Light) will stop flashing when the force has been learned.

The opener has learned the forces required to open and close your door.

The door must travel through a complete cycle, UP and DOWN, in order for the force to be set properly. If the opener cannot open and close your door fully, inspect your door to insure that it is balanced properly and is not sticking or binding. See page 3, “Preparing your

garage door.”

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 use adjustments to compensate for a binding or sticking garage door.

• 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.

ADJUSTMENT STEP 3

Test the Safety Reversal System

TEST

• 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.

• Operate the door in the down direction. The door must reverse on striking the obstruction.

ADJUST

• If the door stops on the obstruction, it is not traveling far enough in the down direction. Complete Adjustment Steps 1 and 2 Programming the Limits and Forces.

NOTE: On a sectional door, make sure limit

adjustments do not force the door arm beyond a straight up and down position. See Figure 3, page 26.

• Repeat the test.

• When the door reverses on the 1-1/2" (3.8 cm) board (or 2x4 laid flat), remove the obstruction and run the opener through 3 or 4 complete travel cycles to test adjustment.

• If the unit continues to fail the Safety Reverse Test, call for a trained door systems technician.

Without a properly installed safety reversal system, persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a closing garage door.

• Safety reversal system MUST be tested every month.

• 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.

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.

ADJUSTMENT STEP 4

Test The Protector System

• 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.

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.

Activate your opener with any of the following:

• The hand-held Remote Control: Hold the large push button down until the door starts to move.

• The wall-mounted control console: Hold the push button or bar down until the door starts to move.

• The Keyless Entry (see Accessories): If provided with your garage door opener, it must be programmed before use. See Programming.

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.

9. If one control (force or travel limits) is adjusted, the other control may also need adjustment.

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" high (3.8 cm) object (or a 2x4 laid flat) on the floor.

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. To avoid SERIOUS PERSONAL INJURY or DEATH from electrocution, disconnect ALL electric and battery power BEFORE performing ANY service or maintenance.

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 control console, 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 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.

They will turn off automatically after 4-1/2 minutes or provide constant light when the Light feature on the Motion Detecting Door Control is activated. Bulb size is A19. Bulb power is 100 watts maximum.
