SOURCE CONNECTIONS (1)
You wire power and audio connections from the channels of a source intercom
station to the row of pins labeled “Sources” (1–8) on the rightmost upper corner
of the rear panel of the RCS-2700.
POWER PATCH PANEL CONNECTIONS (2)
The power patch panel links power from sources to destinations. The leftmost
upper two rows of pins on the rear panel of the RCS-2700 is the power patch
panel. The pins are labeled “Destination Power” and “Source Power.”
DESTINATION CONNECTIONS (3)
You wire power and audio to remote stations and beltpacks on the two rows of
pins labeled “Destinations” (1–24) in the rightmost lower corner of the rear
panel of the RCS-2700.
SOURCE EXPANSION CONNECTIONS (4)
You wire source-8 connection points to each other or to expansion RCS-2700
units on the two rows of pins labeled “Source Expansions” in the rightmost lower
corner of the rear panel of the RCS-2700.
You can wire these four sets of pins in any order. In multi-unit setups, however,
layering the wiring by beginning with the lower-level pins and moving upward is
more efficient.
POWERING THE RCS-2700 AND DESTINATIONS
POWERING FROM PARTY-LINE SOURCES
The first step in an installation is to determine how you are going to supply
power to the RCS-2700 unit and its connected remote stations and beltpacks.
The RCS-2700 unit and its connected remote devices are typically powered by
one or more channels of a main station or power supply. The RCS-2700 unit
itself uses very little power.
Although the system can be powered by one channel of a source station, this is
usually not recommended, especially for complex systems. Using multiple
channels to power the system provides for power redundancy in the case of
outages.
The source intercom station is typically a 2-, 4-, 8-, or 12-channel main or
master station. To power the entire system from a source station, the source
station must have an internal power supply.
Examples of stations that can power an entire system are Clear-Com’s MS-702
2-channel main station or its MS-704 4-channel main station. Two or more
stations can be used as source stations for one system if additional channels are
desired. For example, two MS-704 4-channel stations can be used to provide 8
source channels.
• In a multi-unit setup, the
RCS-2700 main unit and
all RCS-2700 expansion
units must be powered by
the same channel on the
same power supply.
