from ALL moving parts of door.
• NEVER permit children to operate or play with door control

INSTALLATION STEP 6
Install the Door Control
Locate door control within sight of door, at a minimum height of
5 feet (1.5 m) where small children cannot reach, away from
moving parts of door and door hardware. If installing into drywall,
drill 5/32" holes and use the anchors provided. For pre-wired
installations (as in new home construction), it may be mounted to
a single gang box (Figure 2).
NOTE: The functional temperature range of the door control is
between -4° F (-20° C) and 122° F (50° C). Scroll speed of
display is slower at lower temperatures although the door control
remains fully functional.
CAUTION: Continuous exposure of the door control to
temperatures below -22° F (-30° C) may damage the LCD screen.
SPECIAL NOTE: Only one Smart Control Panel ® can be connected
to each garage door opener. If additional wall controls are desired
to operate the same garage door opener, it is recommended to
use model 41A6345-1 wireless wall control as the secondary
door control.
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 W (2) and white/red wire to the R (1).
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:
• 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.
• Drill and install top screw with care to avoid cracking plastic
housing. DO NOT overtighten.
• Insert top tabs and snap on cover.
3. (For 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.
5. Position the antenna wire as shown.
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 power and operate 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.
