• Keep cables at least 18 inches from fluorescent light fixtures,
dimmer controls, and all other wiring. This includes AC wiring,
security cable, cordless phone units, and other control wires.
These can cause a "hum" or "buzzing" sound.
• Keep cables away from objects such as heating and air
conditioning ducts, metal construction plates, and anything else
with sharp edges that can damage the cables.

Careful consideration should be used when determining the location
of the remote stations and master. Since this is a retrofit system you
will not be able to control the location of the existing system. But
please follow the guidelines below if you install any new locations:
• Do not install remote stations in return air ducts.
• Do not install remote stations in exterior walls. Insulation materials
will change speaker range and efficiency. Temperature changes
in the wall will reduce speaker life.
• Do not install remote stations in saunas. They will not withstand
the extreme heat and moisture.
• Do not install remote stations in stud cavities with other wiring or
appliances.
• Do not install remote stations within 18" of dimmers, fluorescent
light fixtures, security wiring, cordless phone units, and other
control wiring.
• Do not install remote stations within 10 feet of other remote
stations or the NM100 master unit. This will cause acoustic
feedback.
• Do not install remote stations in stud cavities with other remote
stations or the NM100 master unit. This will cause acoustic
feedback.
• Do not install remote stations facing other remote stations or the
NM100 master unit. This will cause acoustic feedback.
• Do make sure all rough-ins are level and oriented as shown in
these instructions.
iNstallatioN
Designed to update older intercom systems, the NM100 is a whole-
house music communications system that uses your existing
intercom 3 or 4 conductor system wire. It is designed to provide
years of enjoyment and service to the homeowner.
To ensure that the homeowner receives the high-quality music
and voice reproduction that the system is designed to deliver, it is
important that each step of the installation be done carefully. In the
event you need troubleshooting installation assistance, please call
our technical staff at 1-888-336-6151.
Prior to installing the NM100 system, read and observe the Important
Safety Instructions.
The NM100 retrofit installation is completed using the following
steps:
• Develop the job estimate
• Removal of the old intercom system
• Install the NWH300 or NWH300C rough-in
• Replace the remote stations (Note: do not remove the existing
remote station rough-ins)
• Install the optional NC300 player
• Install the NM100 master and make all remote station
connections
• Test the system
The following tools are required for the NM100 installation. The use
of these or other tools is dependent on the existing intercom system
installation:
• #2 Phillips screwdriver
• Wire stripper/cutter
• Tape measure
• Level
• Tin Snips
• Digital Multimeter (dmm)
• Small (or precision size) Philips/Flat head screw driver
• Power drill with 1" auger
• Small Crowbar
• Large Flat head screw driver
• Rubber mallet
• Extension cord
• Wood chisel
• Dry wall saw
You may not need to use all these tools on each install but having
them handy will make the overall installation process easier.
develop tHe job estimate
It is critical that you determine the complexity of each retrofit
installation prior to developing the job estimate. It is hard to predict all
the unique situations you will encounter in the field. For this reason
NuTone recommends you visit each retrofit site prior to developing
a job estimate and ordering equipment. During this onsite visit it is
recommended that you complete the items listed below:
• Determine the model number and manufacturer of the existing
intercom system.
• Count the number of remote stations and door stations.
• Determine if the door stations and outdoor remote stations are
surface or flush mount.
• Remove the master from the wall to see if any non-standard
installation situations might exist, including:
- Electrical running through the rough-in.
- Telephone wires running through the rough-in.
- S tud spacing that varies from a standard 16" on center
spacing
- T he type of wire used for indoor remote, door and outdoor
remote station runs (NuTone, M&S or other such as telephone
wire). If you encounter non-standard wire contact our Technical
Support team at 1-888-336-6151 for assistance.
- A remote transformer
- A remote door chime
The answers to the above information will help you scope, price and
install the retrofit system.
