in the source power block to the RCS power connection. You must also add a
jumper between the pin-2 and pin-3 (or the pin-5 and pin-6) connections for the
selected source in the sources block. In Figure 2-6, power from Source 8 is being
used to power the RCS-2700.

POWERING THE RCS-2700 FROM A SEPARATE POWER SUPPLY
It is not essential that you power the RCS-2700 unit from the same supply as the
rest of the intercom system. Similarly, if you use the RCS-2700 to switch signals
in a non-intercom application, there may be no intercom power supply and the
destinations will not need +30 VDC power. The following figure shows the
connections needed to power the RCS-2700 from a separate 30 VDC supply.
