Install The Door Control - Chamberlain 3245 1/3 HP Owner's Manual

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 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 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 (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 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 bottom 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 (Figure 5).
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.
