NM100 Intercom ‘Master’ Station
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.
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.
The optional three-note NA3003C or eight-note NA3008C chime modules provide a selection of door
chime sounds.
