INSTALLATION STEP 7
Install the Door Control
Locate door control within sight of door at a minimum
height of 5 feet (1.5 m) where small children cannot
reach, and away from moving parts of 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 or amber 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" (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 WHT
and white/red wire to the RED (Figure 3).
2. Remove cover by gently prying on a side corner
near the top of the cover with a small flat head
screwdriver (Figure 4). Fasten with 6ABx1-1/4" self-
tapping screws (drywall installation) or 6-32x1"
machine screws (into gang box) as follows:
• Drill and 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.
• Install top screw with 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 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. If your access door is near the garage door,
you may run this wire with the Safety Reversing
Sensor wires along the top of the rail. See page 17.
4. Insert all wires through the opening on top of motor
unit above the terminal block on the back panel
(Figure 4).
5. Strip 7/16" (11 mm) of insulation from each set of bell
wires. Connect bell wires to the quick-connect
terminals as follows: white to white and white/red to
red; white to white and white/black to grey (Figure 5).
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 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 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.

• Install door control within sight of garage door, out of
reach of children at a minimum height of 5 feet
(1.52 m), and away from all moving parts of door.
• NEVER permit children to operate or play with door
control push buttons or remote control transmitters.
