Chamberlain 872 Series User Manual

Model Series 872
Indoor/Outdoor Wire-In Light Control
FOR INSIDE USE ONLY WITH INCANDESCENT LAMP CIRCUITS OF 500 WATTS OR LESS. NOT RECOMMENDED FOR
USE IN CIRCUITS WITH FLUORESCENT LAMPS, LIGHT DIMMERS, OR HALOGEN LIGHTING SYSTEMS.
The Control consists of two parts: the power supply and the
receiver. It can replace either single pole (1 switch controlling
a single light) or 3-way switches (2 switches controlling a
single light). Depending on the 3-way switch position, the light
may turn on after a power failure. If properly wired, this will
not occur with a single pole switch installation.
WARNING
Turn off the power to the circuit at the fuse box or
circuit breaker before beginning installation.
Figure 1 illustrates the installation of receiver and
power supply to junction box in interior wall.

Single Pole Switch Instructions, Figure 3:
• Disconnect wires from the junction box switch.
Straighten the ends to make sure the insulation is trimmed
back 1/2" to allow connection of the power supply wires.
• Fold the BLUE power supply wire back as shown and cap
with a wire nut. Screw nut in a clockwise direction to
secure.
• Cap black control wire to one junction box wire and red
control wire to the other. Screw wire nuts on clockwise,
making sure bare wires are covered.
3-Way Switch Instructions, Figure 4:
• At the junction box where the Light Control will be installed,
mark the common terminal wire before disconnecting the
switch. (Common terminal may be marked "common",
"com" or uses a different color screw [gold or silver] than
the other two terminal screws.)
• Disconnect wires from that junction box switch only.
Straighten the ends to make sure the insulation is trimmed
back 1/2" to allow connection of the power supply wires.
CAUTION: If there is a ground on your switch (usually a
bare wire attached to a green screw on switch), connect
the wire to the metal junction box. If the box is plastic,
connect the wire to the metal part of the Control.
• Start by capping the black control wire to the common "hot
or live" wire; and the remaining control wires separately to
the other two junction box wires in any order (but remember
the color of wire #1 connected to the red control wire).

System Model Series 740.
To comply with FCC rules, adjustment or modification of receiver and/or
transmitter is prohibited, except for changing the code setting and replacing
the battery. THERE ARE NO OTHER USER SERVICEABLE PARTS.

• Pry up lower edge of actuator until it separates from
receiver housing. Set actuator aside.
• Remove the 6-32"x1-1/2" screws and unplug receiver from
power supply. Set receiver aside, discard spacers.
• Remove wall plate and set aside for re-assembly.
• Remove screws holding switch to junction box.
• Pull the switch from the junction box to access the
connecting terminals. See Figure 2.
At this point, determine if you have a single pole or 3-way
switch and follow the instructions that apply to your situation.

Screw Wire Nut Clockwise to Secure
• Screw wire nuts on clockwise, making sure the bare wires
are covered. Pull on each wire nut to make sure the
connections are good.
• Carefully pack the wiring back into junction box. Make sure
the wires are not pinched or strained.
• Fasten power supply to selected junction box location with
the #6x1-1/2" flat-head screws provided. (Figure 1).
• Move power supply switch to the right as shown in Figure 5.
Move receiver slide bar so "ON" is visible. The control will
be ON when power to circuit is applied.
• Refer to Figure 1. Position wall plate over the junction box.
Align receiver so that three-pin plug engages holes in power
supply and slide bar engages the power supply switch.
Insert (2) #6-32x1-1/2" screws through fastening holes in
receiver, wall plate and power supply. Tighten securely.
Do not replace the actuator until you have set the code.
