•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.
Caution: Remote Station
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

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
Page
•Replace the remote stations (Note: do not remove the existing remote station
•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
