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.
