INSTALLATION
Connecting the Remote
Wiring
Note: All remote stations, remote controls, speaker volume
controls, and door speaker wiring must return directly to the
master station. Do not connect wiring from speaker to
speaker.
Refer to Figure 8
1. Dress all remote wiring through the center oblong wiring hole
in the top of the rough-in frame.
NOTE: When tightening terminals on the master panel,
support the front side of the panel with your hand. This
will ensure the panel and panel mounting hinges will not
be damaged due to excessive down force on the panel
hinges.
2. Connect the IW-4UL cable for each remote to the appropriate
set of terminal screws at the master station.
Start by separating each of the four (4) wire cables back
approximately 6" from the end. Next, strip approximately 5/8"
of insulation off each wire. To aid in connection, twist three (3)
common wires together as follows:
• Twist all Blue insulation wires together.
• Twist all Copper wires together.
• Twist all Silver wires together.
• Connect all twisted IW-4UL BLUE insulation wires to MIC
terminal on circuit board. Tighten screw.
• Connect all twisted IW-4UL COPPER wires to CONTROL
terminal on circuit board. Tighten screw.
• Connect all twisted IW-4UL SILVER wires to SPKR/"R" GND
terminal on circuit board. Tighten screw.
• Connect each individual RED STRIPED insulation wire to an
individual SPEAKER OUTPUT 1-6 terminals on circuit board.
Tighten screw.
When connecting the cable to the terminals, be sure to observe
all color codes. After completing all connections, check for
shorted wires.
3. Refer to installation instructions packaged with remote
stations, and remote controls for wiring of these units.

• Start by separating the white and gray wires of the IW-2UL
cable approximately 6" back from the end. Next, strip
approximately 5/8" of insulation off each wire.
• Connect the WHITE wire to the SPKR/"R" GND terminal on
circuit board. If more than one volume control is used, twist all
white wires together before connecting to terminal. Tighten
screw.
• Connect each GRAY wire to an individual SPEAKER OUTPUT
1- 6 terminal on circuit board. Tighten screw.
Only one 25 ohm NuTone speaker may be connected to
each volume control. Each volume control/speaker counts
as a remote station (6 maximum). Never use 8 ohm stereo
speakers with this system.
When connecting the cable to the terminals, be sure to observe
all color codes. After completing all connections, check for
shorted wires.
Refer to the installation instructions packed with the speaker
volume control for wiring of this unit.

• If more then one door speaker has been installed, (maximum 3
door speakers) twist the WHITE wires together and connect to
the DOOR GND terminal on circuit board. Tighten screw.
• If more then one door speaker has been installed, (maximum 3
door speakers) twist the GRAY wires together and connect to
the DOOR terminal on circuit board. Tighten screw.
When connecting the cable to the terminals, be sure to observe
all color codes. After completing all connections, check for
shorted wires.
Refer to the installation instruction packed with the door speaker
for wiring of this unit.
