REMOVING THE OLD SYSTEM
Prior to removing the existing intercom system make sure all
power is turned off at the intercom location. Remove the screws
from the intercom master and while removing the intercom,
make sure to carefully label each wire with its corresponding
room location. Disconnect all the remote station and door station
wires from the master. Then carefully remove the existing wall
housing and transformers.
If the existing system was not working prior to replacement,
check each wire run between the remote stations and master
for shorts and wiring integrity. If one of these remote station to
masterwirerunshasashort,re-runthatwirepriortoinstalling
the NM100.  When replacing NuTone 3 wire cable runs, use
NuToneIWA3cable.WhenreplacingNuToneorM&S4wire
cableruns,useNuToneNW4Scable.
Note: if you encounter 120VAC running through the existing
rough-in,haveaqualiedelectricianreroutethe120VACaround
the rough-in.
Ifyouencounteraremotetransformer,anadditionalelectrical
runmayhavetobemadebyaqualiedelectriciantopowerthe
master station and/or optional CD player. Also check to make
sure that the area around the housing is clear of any additional
120VAC runs or other obstructions.
INSTALLING THE ROUGH-IN
The NWH300 and NWH300C rough-ins are designed for 16”
oncenterstuds.Inretrotapplicationsyoumayencounterstud
spacing that varies from this standard. Use the NWH300 rough-
in when you are replacing an existing system with an intercom
only system. The NWH300C rough-in is used for combination
systems only that use the NM100 master and the optional
NC300 6-disc CD player.
Locate the NWH300 or the NWH300C rough-ins. The rough-in
must be positioned so that the transformers are on the bottom of
therough-inasshowninthegurebelow.
If you are replacing the existing master only system with a
combination NM100 master and NC300 CD changer you will
have to cut the rough-in opening larger to accommodate the
larger rough-in. Prior to making the cutout check the stud
cavity for obstructions or items in the wall that may prevent
the transformers from tting in the wall. The NWH300 and
NWH300C transformers drop in from the bottom of the rough-in.
Pleaserefertothenextgureforrough-inplacement.
Connecttheexisting,dedicated120VAC/60Hzlinewithground
connection from the power panel to the rough-in as shown
below. The NM100 requires a dedicated power source to assure
no interference from other equipment caused by looped power
circuits. The ground is necessary for proper radio reception.
Place transformer enclosure from the inside of the wall housing
into the transformer enclosure opening at the bottom of the
rough-in as shown below. Do not run the 120VAC through the
