Connecting to partyline intercom systems

Note: The FS-II Base station has no internal termination. You must provide
external termination on a Clear-Com Master station or a Clear-Com power
supply.
Up to two channels of partyline intercom can be connected to the FS II Base
station. The descriptions below will discuss connections with Clear-Com and
compatible partyline, RTS partyline, and the front-panel settings associated with
these partyline connections.
Using the front-panel display and rotary encoder, the user may go into the PORTS
menu, select the desired partyline channel, and create a five-character
alphanumeric label for it. This is the label that would then appear on any
beltpacks to which that partyline connection was assigned for communications. In
the GROUPS menu, the partyline connection can be assigned as a member of any
of the groups, as desired.
4.2.1

Clear-Com and compatible partyline

Clear-Com and Clear-Com-compatible wired partyline intercoms connect to the PL
CH-A and PL CH-B connectors in a similar manner to connecting beltpacks or
remote stations to the intercom line. Typically that wired intercom connection
would have a 30-VDC current on Pin 2, coming from a main station or an intercom
power supply. The second connector in the pair may be used as a loop-through to
go to other wired partyline stations or beltpacks, or to a second FS II Base
station. The pinout for partyline connector is shown in Table 2.
4.2.1.1 To connect partyline equipment to the Base station
1) Check that the partyline LED on the front-panel is out, which indicates
that the partyline connection is disabled from the Base station.
2) Connect, and if appropriate, power up, the external partyline equipment.
3) Enable the partyline by pressing the "enable" button on the Base station's
front panel.
