Figure 7. An example of an Audiocom intercom system using all locally powered “U”
box stations, with no power being distributed on the intercom channels (dry lines).
Since an Audiocom power supply is not used, the installer must connect a line
termination somewhere in each channel for proper operation. For intercom channel
connections, refer to Figures
8
and
9
. The required line termination is shown in
Figure
10
.
