Figure 6. A two-channel Audiocom intercom system using a PS2000L Power Supply
with “U” boxes. The PS2000L is 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 SS1000 and SS2000 stations may be connected, depending on
each locations’ need to communicate with one or two channels. SS1000 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 SS1000 connection details refer to Figure

for the SS2000, refer to Figure
