13 Room Stations in shared zones on a 3-wire (NuTone retrofit), including 2 Patio

Master Station
The Master Station gives you control over the system intercom and music capabilities.
System setup is established at the master. These settings include: set the clock and
establish music auto on/off times, select the system music source, save preset radio
stations, set the scan mode, and activate the RF Remote. System volume, loudness,
treble, bass, and balance (with optional amplifier) can also be controlled from the
dmc3-4 master. Intercom functionality for each Room/Patio Station is established at the
master by setting the intercom selector switches. Each room station can be set to
Intercom Only, Radio and Intercom, Off, or Monitor.
The dmc3-4 provides the ability to monitor other stations and communicate with Door
Stations. System functionality can also be established to provide Security and Home
Automation features.
