INSTALLATION STEP 7
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 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 2 and white/red wire
to the 1 (Figure 3).
2. Lighted door control: Fasten to wall with 6ABx1-1/2"
self-threading screws.
Multi-function: Remove white cover by gently prying at
slot in top of the cover with a small flat head screwdriver.
Fasten with 6ABx1-1/4" self-threading 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 13.
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 wires.
Insert door control wire into quick-connect terminals by
color: white wire to white, white/red wire to red.
Separate white and white/black wires sufficiently to
connect to the opener quick-connect terminals. Twist like
colored wires together. Insert wires into quick-connect
holes: white to white and white/black to grey (Figure 4)
.
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. See
Step 11 on page 18.
