opener will move in the down direction.
IMPORTANT INFORMATION ABOUT
THE SAFETY REVERSING SENSOR
When properly connected and aligned, the sensor
ill detect an obstacle in the path of its electronic
beam. The sending eye ( ith an orange indicator
light) transmits an invisible light beam to the
receiving eye ( ith a green indicator light). If an
obstruction breaks the light beam hile the door is
closing, the door ill stop and reverse to full open
position, and the opener lights ill 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" 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 ithout additional
hard are.
If it is necessary to mount the units on the all, the
brackets must be securely fastened to a solid
surface such as the all framing. Extension brackets
(see accessories) are available if needed. If
installing in masonry construction, add a piece of
ood 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 hard are) may interrupt the
beam hile the door is closing.
• Be sure power is not connected to the garage door
opener BEFORE installing the safety reversing sensor.
• To prevent SERIOUS I JURY or DEATH from a closing
garage door:
– Correctly connect and align the safety reversing
sensor. This required safety device MUST OT be
disabled.
– Install the safety reversing sensor so beam is O
HIGHER than 6" above garage floor.

The installation surface must be smooth and flat. If
installing into dry all (Figure 1), drill 5/32" holes and use
anchors provided. For pre- ired installations (as in ne
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).
1. Strip 7/16" of insulation from one end of bell ire and
connect to the t o scre terminals on back of door
control by color: hite ire to 2 and hite/red ire to
the 1 (Figure 3).
2. Lighted door control: Fasten to all ith 6ABx1-1/2"
self-threading scre s.
Multi-function: Remove hite cover by gently prying at
slot in top of the cover ith a small flat head scre driver.
Fasten ith 6ABx1-1/4"self-threading scre s (dry all
installation) or 6-32x1" machine scre s (into gang box)
as follo s:
• Drill and install bottom scre , allo ing 1/8" to protrude
above all surface.
• Position bottom of door control on scre head and
slide do n to secure. Adjust scre for snug fit.
• Install top scre ith 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 ire up all and
across ceiling to motor unit. Use insulated staples to
secure ire in several places. Do not pierce ire ith a
staple, creating a short or open circuit. If your access
door is near the garage door, you may run this ire ith
the Safety Reversing Sensor ires along the top of the
rail. See page 14.
4. Insert all ires through the opening on top of motor unit
above the terminal block on the back panel (Figure 4).
5. Strip 7/16" of insulation from each set of ires. Insert
door control ire into quick-connect terminals by color:
hite ire to hite, hite/red ire to red.
Separate hite and hite/black ires sufficiently to
connect to the opener quick-connect terminals. T ist like
colored ires together. Insert ires into quick-connect
holes: hite to hite and hite/black to grey (Figure 4).
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.
6. Use tacks or staples to permanently attach entrapment
arning label to all 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

replace ith a Garage Door Opener bulb.
NOTE: Use only standard light bulbs. The use of
short neck or speciality light bulbs may overheat the
endpanel or light socket.
INSTALLATION STEP 9
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 sho n. Secure ith an overhand knot at
least 1" 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 above
the floor. Secure ith 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 SERIOUS I JURY or DEATH from
a falling garage door:
– If possible, use emergency release handle to
disengage trolley O LY when garage door is
CLOSED. Weak or broken springs or unbalanced
door could result in an open door falling rapidly
and/or unexpectedly.

INSTALLATION STEP 10
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 ith a third
grounding pin. This plug ill 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 b our 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 scre s and set the
cover aside.
• Remove the attached 3-prong cord.
• Connect the black (line) ire to the scre on the
brass terminal; the hite (neutral) ire to the
scre on the silver terminal; and the ground ire
to the green ground scre . The opener must be
grounded.
• Reinstall the cover.
To avoid installation difficulties, do not run the
opener until Step 11 below.
RIGHT WRONG
To prevent possible SERIOUS I JURY 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.
• EVER use an extension cord, 2-wire adapter, or
change plug in any way to make it fit outlet. Be sure
the opener is grounded.

Complete Safety Reversing Sensor
Installation
ALIGNING THE SAFETY SENSORS
Plug in the opener. The indicator lights in both the
sending and receiving eyes ill glo steadily if
iring connections and alignment are correct.
The sending eye orange indicator light ill glo
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 ing nut and readjust,
aiming directly at the receiving eye. Lock in place.
• Loosen the receiving eye ing nut and adjust the
sensor vertically and/or horizontally until it
receives the sender’s beam. When the green
indicator light glo s steadily, tighten the ing nut.
TROUBLESHOOTING THE SAFETY SENSORS
1. If the sending eye indicator light does not glo
steadily after installation, check for:
• Electric po er to the opener.
• A short in the hite or hite/black ires. These
can occur at staples, or at opener connections.
• Incorrect iring bet een sensors and opener.
• A broken ire.
2. If the sending eye indicator light glo s steadily but
the receiving eye indicator light doesn't:
• Check alignment.
• Check for an open ire 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. (If bulbs are not
installed, 10 clicks can be heard.) See page 12.

INSTALLATION STEP 12
Fasten the Door Bracket
Follo instructions hich apply to your door type
as illustrated belo or on the follo ing 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 sho s 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 ith 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" belo
the top edge of the door, OR directly belo any
structural support across the top of the door.
3. Mark, drill holes and install as follo s, depending
on your door’s construction:
etal 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 t o 1/4"-14x5/8" self-threading scre s.
(Figure 2A)
• Alternately, use t o 5/16" bolts, lock ashers and
nuts (not provided). (Figure 2B)
etal, insulated or light weight factory reinforced
doors:
• Drill 3/16" fastening holes. Secure the door bracket
using the self-threading scre s (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 ith 5/16"x2" carriage bolts, lock
ashers and nuts (not provided). (Figure 4)
NOTE: The 1/4"-14x5/8"
self-threading screws are
not intended for use on
wood doors.
To prevent damage to garage door, reinforce inside of
door with angle iron both vertically and horizontally.
