Install The Door Control And Connect All Wires - Chamberlain Security+ 9902 Owner's Manual

Installation Step 7
Install the Door Control
and Connect all Wiring
Locate the door control within sight of the door at a
minimum height of 5 feet where small children cannot
reach, and away from all moving parts of the door and
door hardware.
The multi-function door control is typically attached directly
to the wall, see Figure 1. For pre-wired installations (as in
new home construction), it may be mounted to a standard
single gang box, see Figure 2.
1. Strip 1/4" of insulation from one end of the bell wire.
Connect the wire to the two screw terminals on the back
of the door control as follows: white wire to 2 and
white/red wire to 1. (NOTE: After installation, a green
indicator light behind the white translucent cover will
indicate proper connection. If not lit, the Lock and Light
features will not function (reverse wires to correct).
2. Before mounting, remove the white cover by gently pushing
both thumbs against the upper corners of the cover on the
back side of the door control.
• For standard wall mount, mark the wall about 1-1/4" up
the centerline from the bottom of the door control. Install
a 6ABx1-1/4" self-tapping screw at this point, allowing
about 1/8" to protrude from the wall. Slip the lower part
of the door control over the screw head and adjust for
snug fit. Drill and install the top screw with care to avoid
cracking the plastic housing. Do not overtighten. Run the
bell wire up the wall and across the ceiling to the opener.
Use insulated staples to secure the wire in several places.
Be careful not to pierce the wire with a staple, creating a
short. If your access door is near the garage door, you
may run this wire with the Safety Reversing Sensor
wires along the top of the rail. See page 18.
• For pre-wired installations, partially install a 6-32x1"
machine screw into the bottom of the gang box, allowing
about 1/8" to protrude. Slip the lower part of the door
control over the screw head and adjust for snug fit.
Install top screw with care to avoid cracking plastic
housing. Do not overtighten.
3. Remove the Control Center door on the right panel of
the opener to access the terminal screws.
4. Thread all wires through the opening at the base of the
drive shaft cover, see Figure 3.
5. Insert the remaining wire through the hole in the power
unit and strip 1/4" of insulation from each set of wires.
6. Connect the door control wire to the opener terminal
screws: white to 2 and white/red to 1.
7. Separate the sensor white and white/black wires
sufficiently to connect to the opener terminal screws:
white to 2 and white/black to 3.
8. Attach the User Safety Instruction label to the wall near
the door control, and the Maintenance Instruction label
in a prominent location on the inside of the garage door.
9. Replace the cover by inserting bottom tabs and snapping
into place. To remove the cover after mounting, gently pry
at the top with a paper clip or small flat head screwdriver.
Page 32 explains how to operate the opener using the
door control.
Do NOT connect the power and operate the opener at
this time. See Step 9 on page 22.
Do not connect to live electrical wiring. Connect only to 24 Volt
low voltage wires. Connection to live wires or higher voltage
may cause serious injury from shock, burn or electrocution.
Children operating or playing with a garage door opener can
injure themselves or others. The garage door could close and
cause serious injury or death. Do not allow children to operate
the push button(s) or the remote control(s).
A moving garage door could injure someone under it. Activate
the opener only when the door is properly adjusted, you can
see it clearly, and there are no obstructions to door travel.
