Figure 2. A two-channel intercom system using one PS2000L Power Supply set to
isolate mode. In isolate mode, each intercom channel is a separate party line, and
total current for each channel is limited to 1 amp. Note that both WM1000 and
WM2000 stations may be connected, depending on each locations' need to
communicate with one or two channels. WM1000 stations may be connected to either
channel one or two. Also note that locally powered stations may be connected. This
is recommended when stations are installed at remote locations. Since the PS2000L
provides termination for the intercom channels, no user-installed termination is
required. For WM1000 connection details refer to Figure 6; for the WM2000, refer to
Figure 7
