Figure 5. An example of an intercom system using all local powered stations, with
no power being distributed on the intercom channels (dry lines). WM2000 stations
are shown, but WM1000 stations may also be used. Since an Audiocom power
supply is not used, the installer must connect a line termination somewhere in each
channel for proper operation. The required line termination is shown in Figure 8.
