Install the Door Control
Locate door control within sight of the door at a
minimum height of 5 feet 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 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" 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 white 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" 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.
4. Strip 7/16" 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
(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.
5. 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. See Safety Reversing Sensor Instructions
beginning on page 21.
