CAUTION
INSTALLATION STEP 6
Install the Door Control
Locate door control within sight of the door at a
minimum height of 5 feet (1.5 m) 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" (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 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:
• 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 top 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" (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 (Figure 4).
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 17.
To prevent possible SERIOUS INJURY or DEATH from
electrocution:
• Be sure power is not connected BEFORE installing door
control.
• 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 control transmitters.
• Activate door ONLY when it can be seen clearly, is
properly adjusted, and there are no obstructions to door
travel.
• ALWAYS keep garage door in sight until completely
closed. NEVER permit anyone to cross path of closing
garage door.
