PRECAUTIONS AND GUIDELINES
The NuTone IM-4406 master station has been designed for
ease of installation. Please read and follow ALL installation
instructions, guidelines and precautions. Any deviation from
these instructions or miswiring combinations may result in
unit failure and void of warranty.
WARNING!
120 Volt AC Power to Transformers in the IR-105
Rough-in MUST Remain OFF until ALL System Wiring
at the Master and Remote Stations is Complete.
• Observe all local building regulatory codes in your area.
•All screw terminals at the master and remote stations must
be secure.
• Observe all color code connections of wires when
connecting the remote stations to the master.
• The IM-4406 is designed to be installed with only NuTone
specified wire. No other wire should be used. The use of
wire other than NuTone wire will void all NuTone warranties
and may result in faulty installation and improper operation.
Use NuTone IW-2, 22 ga. twisted pair for connecting:
• Door speakers to master
• Remote controls to speakers
• Speaker volume control (IC901) to master
• Speaker volume control (IC901) to speakers
•Electronic chime audio output to master
• Pushbutton to chime module
Use NuTone S-143, 18 ga. twisted pair for connecting:
• Pushbutton to electronic chime
•Electronic chime to chime transformer
Use Nº14/2 power cable with ground, Class 1 UL Listed
(Observe local codes) for connecting:
•Transformers to 120v AC
Use shielded audio cable for connecting external audio
sources to the master station.
REMOTE STATION WIRING
An individual 6-wire cable (IW-6) must be connected from
each remote station or remote control location to the master
station’s terminal board.
Maximum station wire length: 750 ft.
Maximum total length of IW-6 cable per system: 4,000 ft.
MAXIMUM NUMBER OF REMOTE STATIONS
The master station will accommodate up to 9 connections
at the terminal board. These connections can be any
combination of remote stations, remote controls or volume
controls. It will also accommodate 3 door speaker
connections.
If more than 9 stations are required, use the optional
Model Nº IA-440 expansion kit. This will allow an additional
6 connections at the master.
IMPORTANT!
NuTone cannot be responsible for
improper system operation that results from
interference generated by light dimmers, fluorescent
lighting fixtures, and similar electrical products. Such
interference must be corrected at the source. TO HELP
REDUCE THIS INTERFERENCE, ALL WIRING
CONNECTIONS TO THE MASTER MUST BE PLACED
AT LEAST 12 INCHES FROM ANY AC POWER WIRING.
AVOID RUNNING INTERCOM WIRES PARALLEL TO
AC POWER WIRING.
INSTALLATION
NOTE: NEVER connect more than one remote
station to a set of screw terminals.
IMPORTANT WARNING!
THE POWER TRANSFORMER CONTAINS AN
INTERNAL FUSE.
DO NOT SHORT THE LOW VOLTAGE CONNECTING
SCREWS OF THE TRANSFORMER OR THE
TRANSFORMER WILL BE DESTROYED!
WIRING SPECIFICATIONS
See the IR-105 master rough-in frame installation instructions
for detailed wiring information.
Use NuTone IW-6, 3 twisted pair for connecting:
• Remote controls to master
• Remote stations to master
MOUNTING THE TERMINAL BOARD
1. Remove and clean any drywall debris or dust from the
rough-in before beginning installation.
2. Refer to Figure 1. Locate the terminal board in the left
rear section of the rough-in frame.
3. Use four (4) Nº 6 x 3⁄8“ screws supplied to secure the
terminal board to the rough-in frame.
4. Make certain the lower right-hand screw is secure and
snug against the ground lug which covers the mounting
hole in the terminal board. Do not bend ground lug.
Make sure it is positioned between the screw and
terminal board.
CONNECTING THE REMOTE WIRING
1. Dress all remote wiring through the rectangular holes
in the upper right and left sides of the rough-in frame.
All wiring connections are made to the master station’s
terminal board.
2. Refer to Figure 2. Connect the IW-6 cable from each
remote to the appropriate set of terminal screws at the
master station’s terminal board. When connecting the
cable to the terminal board, be sure to observe the
matching of all color codes.
Connect: RED to RED
RED/WHT to RED/WHT
BLK to BLK
BLK/WHT to BLK/WHT
ORN to ORN
ORN/WHT to ORN/WHT
Only connect one remote to each set of screw terminals.
After completing all connections, check for any shorted
wires. Dress cables flat against the terminal board to allow
space for the master station to be properly secured.
3. Refer to installation instructions packaged with the remote
stations and remote controls for wiring these units.
4. Refer to Figure 3. Use the Wire Matching Chart if you are
retro-fitting a system with the previously used IW-6R cable.

WARNING! NEVER EXCEED A TOTAL OF 15 NUTONE
25 OHM SPEAKERS ON THIS SYSTEM.
WARNING! NEVER USE STANDARD 8 OHM STEREO
SPEAKERS ON THIS SYSTEM. USE ONLY NUTONE
SPECIFIED SPEAKERS ON THIS MASTER.
IMPORTANT
DO NOT APPLY POWER TO THE SYSTEM UNTIL ALL
CONNECTIONS ARE COMPLETE AT THE MASTER
AND REMOTE STATIONS.
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!

CONNECTING VOLUME CONTROL WIRING
Refer to Figure 4. If a NuTone Volume Control is installed in
the system, connect the control’s IW-2 wiring to the ORN and
ORN/WHT screw terminals at the master station. Only ONE
NuTone speaker may be connected to each volume
control. Each volume control/speaker counts as a
remote station. Remember: The maximum remote
connections to the Master Station is 9. Adding the
optional IA-440 expansion module will increase the
system remote capability to 15 stations.
Refer to the installation instructions packed with the speaker
volume control for wiring this unit.
CONNECTING DOOR SPEAKER WIRING
The Door Speakers connect to the Master Station Terminal
Board with twisted pair IW-2 wire.
1. Refer to Figure 5. Connect the two wires from the Door
Speaker(s) to the 2 screw terminals marked DOOR
SPEAKER on the master station terminal board.
PREPARING MASTER STATION PANEL FOR
OPTIONAL DOOR RELEASE PUSHBUTTON
To remove the pushbutton cover, position the master station
face up. Be careful not to damage the cables on the back of
the unit.
1. Refer to Figure 6. Open the left-hand door on the master
station panel.
2. Cut the 4 retainer webs from the pushbutton cover.
3. Remove cover. The door release pushbutton will be
installed and connected after the master panel has been
mounted to the rough-in frame.
MOUNTING THE OPTIONAL CHIME
MODULE IN THE MASTER STATION PANEL
1. Position the master station panel face down on a soft cloth.
2. Refer to Figure 7. Align the optional NuTone IA-28 or
IA-29 chime module onto the mounting bracket located in
the master station.
3. Apply firm, but even pressure to each side of the chime
module until it snaps into place.
4. Plug the 4 pin connector on the module into the connector
located on the master. When properly installed, the ribbon
cable will point away from the master station’s circuit
boards, as illustrated.
5. Connection from the pushbuttons to the master will be
made after the master panel has been mounted.

MOUNTING THE MASTER STATION
NOTE: If an optional IA-440 expansion module is to be
installed into the IM-4406 master station, it should be
installed before mounting the master station. Refer the
installation instruction provided with the expansion module
before performing the following mounting steps.
1. Refer to Figure 9. Use two (2) #6x3⁄8˝ screws per bracket
to attach each of the four (4) mounting brackets to the
rough-in frame. Before tightening, slide the bracket so it is
flush with the wall surface (flush with rough-in frame if the
rough-in is installed after the wall board). Tighten all eight
(8) screws.
2. Refer to Figure 10A and 10B. For rough-in frames which
are recessed into the wall opening, insert two (2) shoulder
screws (provided) into the front two holes in the rough-in
frame. For rough-in frames which are mounted flush with
the wall, insert two (2) shoulder screws into the back two
holes in the rough-in frame.
3. Refer to Figure 11. Attach master panel to rough-in
frame by placing mounting hinge keyhole slots over
shoulder screw heads in the rough-in frame.
4. Refer to Figure 12. Slide master station panel to the right,
then forward until it is flush with the wall surface.
5. Align master panel with rough-in frame.
6. Refer to Figure 13. Attach support strap to rough-in
frame by attaching metal hook into hole in top of rough-in
frame. Using pliers, squeeze hook closed. Hook must not
come loose when master is later secured.
