Connecting to an SSA-424

4-Wire Call Signal Connections

NOTE: These connections will require the call signal option. Part Number 9002705500.

Call Signal Connections for ADAM, ADAM CS, and Zeus

You can use the General Purpose Interface (GPI) connector to interface the call signals. The pin-out of the connector is the

same for all of these intercom systems.

ADAM GPI Connector: XCP-ADAM-MC, J11

ADAM CS GPI Connector: J903

Zeus GPI Connector J27

If you intercom system is equipped with a UIO-256 Universal Input / Output Frame, you can also use that for connections.

As an alternative to using the GPI, you can use external components to send and receive call signals.

Call Signal Connections for Other 4-Wire Communications Systems

4-wire Call Send and Call Enable/Inhibit

The SSA-424 accepts a switch-contact input from the 4-wire system and then generates a call signal output to the 2-wire

system. The SSA-424 also accepts an option switch contact input to enable or inhibit call signalling between the 4-wire and 2-

wire systems.

4-Wire Call Receive

The SSA-424 receives call signals from the 2-wire system, then converts this to relay contact closure for use as a 4-wire call

receive indication. The SSA-424 also provides +5 VDC which can be connected to the relay contacts to generate a DC output

signal instead of a contact closure.

The SSA-424 power indicator flashes whenever a call signal is received from either 2-wire line. This can be used as an

incoming call indication for the 4-wire system, if desired, and the level display should provide an indication of which line is

calling.
