INSTALLATION STEP 6
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,
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).
NOTE: The functional temperature range of the door
control is between -4° F (-20° C) and 122° F (50° C).
Scroll speed of display is slower at lower temperatures
although the door control remains fully functional.
CAUTION: Continuous exposure of the door control to
temperatures below -22° F (-30° C) may damage the LCD
screen.
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 W (2) and white/red
wire to the R (1).
2. Remove cover by gently prying at slot in top of the
cover with a small fl at head screwdriver. Fasten with
6ABx1" 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 fi t.
• 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.
• 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.
