Power from the source intercom station’s one channel is patched to the power
connection for the RCS-2700 and to the power connections for all remote
destination stations.
The main advantage of this wiring is its simplicity. The disadvantage is that a
short on one destination’s cable can bring the whole system down. When power
monitoring is done with the RCU-67 or the RCS-WIN PC program, it will not
be possible to detect which destination's power is shorted.

Powering from a Separate Power Supply
The third way of connecting power involves the use of a separate high-current 30
VDC power supply. The power supply is connected directly to the RCS-2700’s
power input connector, and fuses or circuit breakers are wired as shown in Figure
2-4 to protect each destination’s power circuit individually.
In this configuration, either an RCU-67 Remote Control Unit or a PC with the
RCS-WIN program installed will be able to detect precisely which destination’s
power circuit is shorted.
