various level ranges available on the input and output refer to the
FOR-22 manual (part 810306Z).

Call Signal Input

The Call Signal input is used to receive a call/logic input signal from an
external device and send it to the matrix. The voltage across the pins
required to receive a call signal ranges from 4 to 50V; it can be either
positive or negative polarity or AC. The input will draw between 4 and 8
mA.

Relay Contacts

Each FOR-22 interface channel features a relay that is associated with
the logical call signal output of a port. A relay’s function depends on
the function assigned to the FOR-22 port through the Eclipse
Configuration System program. A relay can be assigned to operate
with any label in the system: when that label is activated (either by a
talk, listen, or both, as set from the configuration program), the relay
will activate. For details on configuring the use of a relay, see the
Eclipse Configuration System Manual (part 810299Z).

The relay can be used to activate an external device, such as an
applause light in a studio, a cue light, or a security-door lock. The
relays feature both “normally open” and “normally closed” contacts.
The contacts are rated at 1 A at 24 VDC; they are not designed for
switching mains AC line voltage.

CCI-22 PARTY-LINE INTERFACE WIRING

The CCI-22 party-line interface connects two 2-wire full-duplex
party-line circuits to the matrix. This interface has its own manual in the
Eclipse manual set. The following discussion gives an overview of the
wiring of this interface.

The CCI-22 interface uses each of the RJ-45 connectors on its rear
panel for connection to the matrix port. One RJ-45 connector is for the
first channel of the interface. The second RJ-45 connector is for the
second channel.

The user side of the CCI-22 for each channel appears on a pair of
DB-9M connectors on the rear of the interface. Figure 4-15 shows the
pinout of either one of these connectors. Both DB-9s are paralleled
such that both party-line channels are available on each connector. It
is possible to wire one DB-9 connector as channel #1 and the second
DB-9 as channel #2 or bring both channels out either DB connector
together to create a TW-type, party-line connection. Refer to the
CCI-22 Interface Instruction Manual (part 810307Z) for more
information.
