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. The installation surface
must be smooth and flat. If installing into drywall
(Fig. 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 (Fig. 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 (Fig. 3).
2. Lighted door control: Fasten to wall with
6ABx1-1/2" self-tapping screws.
Multi-function door control: Remove white cover
by gently pushing both thumbs against upper
corners of cover on back side of door control
(Fig. 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.)
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. Connect bell wire to the opener terminal screws as
follows: white to 2 and white/red to 1. (Fig. 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.
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, 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.
