INSTALLATION STEP 6

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
prewired 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. 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:

• 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 top 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. 

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 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 16.

To prevent possible SERIOUS INJURY or DEATH from
electrocution:
• Be sure power is not connected BEFORE installing door

control.

• Connect ONLY to 24 VOLT low voltage wires. 
To prevent possible SERIOUS INJURY or DEATH from a
closing garage door:
• Install door control within sight of garage door, out of

reach of children at a minimum height of 5 feet (1.5 m),
and away from all moving parts of door.

• NEVER permit children to operate or play with door

control push buttons or remote control transmitters.

• Activate door ONLY when it can be seen clearly, is

properly adjusted, and there are no obstructions to door
travel.

• ALWAYS keep garage door in sight until completely

closed. NEVER permit anyone to cross path of closing
garage door.
