The NM100 system is a full-function
intercom and music distribution system
designed for retrofit applications in
residential use. The ‘Master’ unit can
replace older intercom systems that use
three-wire or four-wire connections to the
room stations. The system supports up
to 15 remote stations when retrofitting a
4-wire system, and 13 remote stations
when retrofitting a 3-wire system. The
built-in AM/FM radio tuner allows setting
eight AM station presets and eight FM
station presets. The backlit liquid crystal
display shows the operation mode, audio
source, radio frequency, volume setting,
and time. With the optional NC300 6-disc
CD changer installed, the display shows
the disc number selected and the track
number currently playing.
Remote stations have pushbuttons that
control the system operation. Retrofit
indoor and outdoor remote stations
connect to the ‘Master’ unit using the
installation’s existing wiring. All 4-wire
remote station models can select ‘talk’ or
‘listen’ to other remote stations, door
speakers and the master unit. The 3-wire
models can select ‘talk’ to other remote
stations, master unit and 'talk/listen' to
door speaker. Each has an intercom
volume control.
The NRS103 and NRS104 indoor
remote stations and NPS103 and
NPS104 outdoor remote stations can
select the audio source, scan preset
radio stations and set the master music
volume.
