INSTALLATION STEP 6

Install the Door Control

Locate door control within sight of the door at a minimum height
of 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 fl at. If installing into drywall
(Figure 1), drill 4 mm 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 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. Remove white cover by gently prying at slot in top of the cover
with a small fl at head screwdriver (Figure 4). 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 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.
• Install top screw with care to avoid cracking plastic housing.
Do not overtighten.
• Insert bottom tabs and snap on cover. (To remove cover after
mounting, gently pry at top with paper clip or small fl at head
screwdriver.)
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 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 5).
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.
