CommLink FXC-S201 Fiber Optic Intercom Link Power Options
The CommLink FXC-S201 Fiber Optic Intercom Link is powered through an attached
external power supply or from power received from the Two-Wire intercom connection.
The following table shows how a CommLink FXC-S201 Fiber Optic Intercom Link unit can
be powered:
Model
12 Volt Power
Supply
30 Volt Power Supply
30 Volt Power Output
to Belt Packs*
FXC-S201-W13
FXC-S201-W15
FXC-S201-S13
ADAP-AC-04
with 4-pin XLR Can be powered from
Intercom system when
in Two-Wire mode 30 Volts is provided on
RTS/CC-1 and CC-2
XLR connectors.
* 30 Volts is output from the CommLink FXC-S201 unit when it has 12V power applied.
When no 12V power is applied (2W Power switch is on EXT), the CommLink FXC-S201 Fiber
Optic Intercom Link unit derives power from the intercom connection and all Belt-Packs
derive power from the Intercom system or from internal power sources.
When powered by the 12 Volt power supply, the CommLink FXC-S201 Fiber Optic Intercom
Link will power five intercom belt packs (10 total on the system) or two remote matrix
stations per channel. If the system has self-powered belt packs attached (30V), and the
external 12 Volt power supply is also attached, the 12 Volt supply takes priority in powering
the CommLink FXC-S201unit.
