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).
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
2 and white/red wire to the 1.
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:
• 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.
• 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.
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
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.
