SYSTEM POWERING
Typical Clear-Com systems consist of a main station and multiple remote
stations. The remote stations are powered from the main station through the
intercom cable (Figure 2-5).
Figure 2-5 Typical Single Power Source System
Clear-Com power supplies can be paralleled to increase the number of remote
stations that can be operated in a system (Figure 2-6). The termination
switches in the second power source would need to be in the off position.
Note: The RMK function will not work on a system that has two or more
power supplies.
