INSTALLATION STEP 6
Install the Door Control
Locate door control within sight of the door at a
minimum height of 5 feet where small children cannot
reach, and away from moving parts of the door and
door hardware. 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 1/4" 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 1 (Figure 3).
2. Remove white cover by gently pushing both
thumbs against upper corners of cover on back
side of door control (Figure 4). Fasten with
6ABx1-1/4"self-tapping screws (standard
installation) or 6-32x1" machine screws (into gang
box) as follows:
• Drill and install bottom screw, allowing 1/8" 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. (To remove
cover after mounting, gently pry at top with paper
clip or small flat head screwdriver.)
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. Connect bell wire to the opener terminal screws as
follows: white to 2 and white/red to 1 (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.
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 Safety Reversing Sensor Instructions
beginning on page 17.
