Music Intercom Features Explained
A. Music/Intercom Speaker Capacity
F. Monitors Room Speaker
The number of rooms you can have intercom
communications and play music in depends on the
number of intercom speakers you can put on the
system.
On radio/intercom units, position room selector
switch at the master to Monitor to instantly check
on a room. On the IMA-516 and IM-5000, press
the “TALK LOCK/MONITOR” button on the
room speaker.
B. Door Speaker Capacity
All NuTone music/intercom and intercom systems
can handle three doors except the IMA-516 which
can handle up to two door speakers.
G. Selective Call
Selective intercom calling is available on the IM-
5000. To make a selective call, first enter the two-
digit room number corresponding to the room you
wish to call. After the second digit is pressed, a
call tone is heard at both stations to indicate a call
is being made and intercom audio from the called
station is heard. To talk to the selected room, sim-
ply press the “TALK” button. To hear the reply,
simply release the “TALK” button.
C. Number of Room Selector Switches
Room selector switches allow you to choose what
is sent to each room speaker. The room switch can
be set to one of four settings:
1. Radio Intercom
2. Intercom Only
3. Monitor
4. Off
H. Room to Rooms (All Call) Intercom
Press a button in any room to speak to the other
rooms. Most NuTone intercom systems are “all
room” intercom systems. This means that when
you press the talk button you speak to all rooms
that have intercom speakers. Our IM-5000 is both
an “all call” and “selective call” system. With this
system, you can specifically call one room from
another. A selective call intercom system is well
suited to business installations like dentist or
doctor’s offices or other small businesses. One
advantage to an “all room” system is that often
when calling an individual, particularly children,
they may have moved from one room to another.
With a NuTone “all call” intercom you’ll immedi-
ately be able to communicate with the individual.
Why would you have a speaker switch set to any-
thing other than the first - Radio Intercom? Well,
if you’re an early riser, you may want to set the
bedrooms to Intercom Only. That way you can
play music and not disturb your sleeping children
or spouse. The Monitor setting allows you to
monitor rooms and broadcast the sound from the
monitored room through the rest of the intercom
speakers inside and out. Off setting turns off all
intercom, music, and chime sounds to the room.
The IM-4406 and IM-3303 systems have these
four switch options. The IM-3204 has Radio
Intercom, Off and Monitor. Monitor, intercom,
and music control features for the IMA-516 and
IM-5000 are located directly on the room speakers.
D. Music Muting during Intercom or Chime
During intercom, the music is muted allowing for
clear voice communication. The music is also
muted when the chime button is pushed.
E. Constant-On 24 hour Intercom
The intercom is always on. You can use the
intercom function at a moment’s notice.

I. Room to Doors Intercom
Press the door talk button on a room speaker to
speak with a visitor at the door. Release to hear
the reply.
ton door answering is more convenient because
you are less likely to miss part of your visitor’s
response. It is not dependent on how quickly you
press the second button to listen.
J. Number of wires in Intercom Speaker Cable
If you wish to replace an existing Music/Intercom
to take advantage of updated styling and new fea-
tures, you need to be aware of the cable used to
wire the system you’re replacing. If you can,
you’ll want to use the cable already in the wall. In
most cases, a current NuTone 3-wire system can
replace an older 3-wire system, 4-wire replace 4-
wire, etc. You may also be able to replace a differ-
ent brand intercom with a NuTone system. Our
Technical Support Group would be pleased to
help you determine your options, please phone us
at 888-336-6151, or fax us at 513-527-5122.
Please have the brand, model number, number of
speakers, number of wires and any other details
you may have on your system available when you
call.
N. AM/FM Radio
O. CD Player
Many of our intercoms have built-in AM/FM
radios so you can enjoy your favorite radio station
throughout your home. Model IM-4406 has a
built-in CD Player.
P. Electronic Tuning
Allows for easy, accurate tuning of your favorite
radio station.
Q. Remote Radio On/Off, Memory Control
Radio operation can be controlled from any inter-
com speaker. Press the “RADIO CONTROL/END
CALL” button at any intercom speaker for 2 sec-
onds to turn the radio ON. To turn the radio OFF,
again, press the “RADIO CONTROL/END CALL”
button for 2 seconds. To sequence through each pro-
grammed radio memory channel, momentarily press
the “RADIO CONTROL/END CALL” button.
K. “Hands Free” Answering
Ideal for the couch potato in all of us. The person
being called doesn’t have to rise from the chair to
answer. In systems without the “Hands Free” cir-
cuitry, the person being called needs to go to the
intercom speaker and press a button to respond.
On IM-5000 and IM-4406, all calls from master
or any speaker are “Hands Free”. On IM-3303,
only calls from the master are “Hands Free”.
R. Station “Recall” Memory
Program your favorite stations into memory for
easy recall later.
S. Aux Audio Input(s)
The master has audio input(s) allowing you to add
a NuTone Cassette player, to patch in the
audio from your multi-disc CD player or home
theater for broadcast throughout your home.
L. Intercom Only Switch Settings
If you’re an early riser, you may want to set the
bedrooms to Intercom only. That way you can
play music and not disturb your sleeping children
or spouse.
M. One Button Door Answering
To answer the door, you press one button to speak
to the visitor, release the button to listen to their
response. All NuTone systems offer one button
door answering. In some systems you press one

Music Intercom Features Explained
T. Bass/Treble Controls
Y. Digital Clock can turn Radio on and off
The Music Intercom system can be used as a whole
house alarm clock. Set the clock to turn music on
in the morning and have it gently wake your chil-
dren. The digital clock can also be used as a sleep
timer to turn music off at a certain time. This fea-
ture also can be used as a deterrent to intruders.
The timer can be set to turn music on while you are
away - making a thief think you are there, discour-
aging them from entering your home.
Tone controls allow you to fine tune the music out-
put. NuTone music intercom systems have separate
bass and treble controls.
U. Loudness Control
When activated, the loudness control boosts the
bass and treble response during low volume use.
V1. Tune Selectable Chime Option
The IA-29 chime module offers 10 different tunes
plus Westminster chime. To select a different tune,
press the tune change switch through the tune
change access hole located on the master panel.
Also includes a two and one note chime sound for
the side and rear doors. Module mounts and plugs
into master unit.
Z. Time and Radio Backup
A built-in electrical backup system maintains your
time and radio memory channels up to 30 hours
during a power outage.
AA. Lighted Function Display
The lighted digital display is easy to read day
or night.
V2. Westminster Chime Option
The IA-28 chime module offers a Westminster
chime sound for the front door, and a two/one note
chime for the side and rear doors. Module mounts
and plugs into master unit.
BB. Self Diagnostic Troubleshooting Circuitry
For proper performance and operation of an
Intercom, it is important that all wires are securely
attached to the proper terminal. Otherwise, certain
features of the intercom may not work, there could
be humming or no sound at all. NuTone’s self diag-
nostic circuitry allows the installer to easily check
the installation and if there is a misconnected wire,
identify which room is affecting the system. This
helps ensure that when the installer leaves, your
system is operating as it was designed to.
V3. External Chime Option
Most NuTone electronic chime models can be con-
nected to the master unit to allow chime sound to
be heard over the room speakers.
The addition of a chime module or NuTone elec-
tronic chime to your NuTone intercom system
ensures you’ll never miss a guest again by sound-
ing the chime through all intercom speakers that
are turned on.
CC. Built-in Surge Protection
Mov’s and diode clamping circuitry help minimize
the potential for damage to your NuTone music
intercom system from line surges and electrical
storms.
W. Color Choices
All NuTone intercoms are available in white. Some
are also available in black and biscuit. Our cassette
player is available in white. Speakers are available
in white. Some speaker models are available in
biscuit, black or brown. Door speakers are avail-
able in antique brass, bright brass, white or brown.
DD. Privacy Switch on Intercom Speakers
Switch on speaker can be used to turn off the abili-
ty to monitor that room. Ideal for master bedrooms
and baths.
X. Digital Clock
EE. End Call Button
The IM-3303 and IM-4406 music intercoms
feature a built-in digital clock.
Allows intercom call to be manually ended.

tape over and over. Includes fast forward/rewind
functions and a convenient tape storage area. Can be
used with IMA-516, IM-3204, IM-3303, IM-4406
and IM-5000 series.
Never miss a guest again. Chime rings through
every intercom speaker throughout your home.
The NuTone IA-29 chime module offers the ability to
easily select from ten different tunes for the front
door and change them as your mood desires. Melody
choices include: Westminster 8-notes, Westminster
4-notes, Anniversary Waltz, Beethoven’s Fifth, Dixie,
Greensleeves, Happy Birthday, Jingle Bells, Joy to
the World, Mazel Tov, Oh Tannenbaum and the Star
Spangled Banner. The second door rings two notes
and the third door rings one note.
Music and Intercom 25 ohm Speakers
NuTone offers a wide selection of speaker options;
wall-mount, ceiling-mount, indoor and outdoor
speakers. To determine which speakers are available
for your system, see the system diagrams in this
guide.
The IA-28 chime module plays 8-note Westminster
for one door, two notes for second door and one note
for a third door.
Music Input Plate
Connect your existing music and TV audio compo-
nents to a NuTone system. Allows you to follow the
action of a sports event when you leave your home
theater room by broadcasting the audio throughout
your home. Can be used with IMA-516, IM-3204,
IM-3303, IM-4406 and IM-5000 series.
Surface Mount Housings
Surface mount housings are available for most
NuTone room speakers as well as door speakers.
They make it a little easier installation as you do not
have to cut an opening to recess mount the speaker.
They are especially handy when you want to put a
door speaker on a brick surface or if you want to
have a speaker on a fire rated wall (typically this is
the wall between an attached garage and the living
space).

Wiring Your System
What Cable is Needed
VERY IMPORTANT - Use only NuTone intercom cable to wire NuTone intercom system. NuTone intercom cable is
designed and constructed to electrical specifications necessary for satisfactory performance.
Use of “generic” cable can result in humming, interference and feedback in the installed system. After the house is
finished, it will be time consuming and expensive to correct problems caused by use of the wrong cable. NuTone
will not warranty systems where NuTone intercom cable is not used.
• On all models except the IMA-516 and IM-5000, you should plan a separate “home run” cable from the master
housing to each individual speaker or volume control location. Do not loop cables from one speaker or volume
control to another. Electronic feedback or poor system performance will result. Models IMA-516 and IM-5000
can have speakers “looped”. See IMA-516 and IM-5000 instruction sheets for details.
• Do not splice cables. Always install an uninterrupted cable from the master to the intercom speakers or volume
controls and from the volume controls to the music speakers.
• Plan to keep cables 18 inches from fluorescent light fixtures, light or fan dimmer controls and any other wiring
(electrical power, security system, etc.) to minimize risk of system interference.
• Plan cable routes away from metal (heating and air conditioning ducts, construction plates, etc.) or any other
objects that may have sharp edges that could cause damage to the cables. If cables must be routed through metal,
use rubber grommets in the holes to protect the cables.
• Cables installed outside the house are to be routed through PVC conduit to protect them from the elements.
The cables are not constructed to be UV weatherproof.

Where to Install Music Speaker
Volume Controls
siderations:
Select music speaker volume control location with the
following considerations:
• Choose master location with regard to
residents’ lifestyle, either centrally located
(living room, kitchen, central hallway, etc.)
or securely located (master bedroom).
• Except for model IC-902, do not locate volume
control in a sauna or outside. Extreme heat and
moisture will adversely affect its performance
and life.
• Locate master in an accessible area. Do not
locate closer than 2 inches to a corner,
cabinet, counter top, etc.
• Locate volume control a minimum of 18 inches
from fluorescent light fixtures, light or fan dim-
mer controls and other wiring (electrical power,
security system, etc.) to minimize risk of sys-
tem interference.
• Do not locate master in an outside wall.
Insulation and temperature changes may
adversely affect unit’s performance and life.
• Do not connect more than one speaker to a
monaural volume control or one pair of speak-
ers to a stereo volume control.
• Select a location that will not restrict wire
routing from the speaker to the master.

Master Bath (allows you to step out of
the shower and easily answer the door)
Select speaker location with the following considerations:
• Choose location where open doors or
furniture will not cover the speakers.
• Do not locate speaker in an outside wall
except for speakers intended for outdoor
use. Insulation and temperature changes
may adversely affect the speaker’s
performance and life unless it has
been designed for outdoor use.
• Do not locate speaker in a sauna.
Extreme heat and moisture will
adversely affect the speaker’s
performance and life.
• Locate speaker a minimum of 18 inches from fluorescent
light fixtures, light or fan dimmer controls and any other
wiring (electrical power, security system, etc.) to minimize
risk of system interference.
• To avoid audio feedback noise, locate intercom speaker at leas
10 feet from another intercom speaker and keep intercom
speakers from directly facing each other or from being mounted
within the same wall cavity. Never locate two intercom speakers in the same room.
• For optimum stereo separation, stereo music speakers should be located
6 to 10 feet apart. Ideally, you will also want to keep the speaker(s) 2 feet from any sidewall, ceiling or floor.
• Do not locate more than one speaker in a room except when installing the SR-9000 stereo receiver.
