2.5 4-WIRE CALL SIGNAL CONNECTIONS

These connections require the call signal option.
2.5.1 Call Signal Connections for ADAM,
ADAM CS, and Zeus
You can use the General Purpose Interface (GPI) connec-
tor to interface call signals. The pin-out of the connector
is the same for all of these intercom systems (Table 1).
ADAM GPI Connector: XCP-ADAM-MC, J11
ADAM CS GPI Connector: J903
Zeus GPI Connector: J27
If your intercom system is equipped with a UIO-256 Uni-
versal Input/Output Frame, you can also use that for con-
nections (Tables 2 and 3, page 12).
As an alternative to using the GPI, you can use external
components to send and receive call signals as described
in paragraph 2.5.2.
Typical GPI connections are shown in Figure 5. Note that
the example uses GPI outputs #1 and #2 and GPI input
#1. You may substitute other GPI inputs and outputs.
Important Note for ADAMedit users: ADAMedit ver-
sion 1.06 includes a feature which lets you invert the ac-
tion of the GPI outputs. By default, these outputs are set
to duplicate the action of the RTS FR9528 Relay Frame
accessory. This is the correct setting for use with the
SSA424. To check the ADAMedit setting, select Intercom
Configuration in the Options menu. Click on the Options
tab, and make sure that there is a check mark next to Con-
figure onboard GPI outputs in FR9528 mode.
CLEAR-COM APPLICATION NOTE: IF A
CALL ENABLE/INHIBIT SWITCH IS NOT
USED, A JUMPER MUST BE
INSTALLED TO ENABLE CALL SIGNALING.
THE JUMPER IS NOT REQUIRED FOR ANY
OTHER APPLICATION.
Figure 5. Call signal connections for ADAM, ADAM CS, or Zeus Intercom Systems. This example uses GPI outputs #1
and #2 and GPI input #1; however, you may use any other available GPI inputs and outputs. The Call Enable/Inhibit connec-
tion is optional. It gives you the ability to disable call signaling using a GPI output. However, when connecting to a Clear-Com
intercom system, if an enable/inhibit switch is not connected, a jumper must be installed as shown to enable call signaling. The
jumper should not be installed for any other application. Note: You do not have to use GPI outputs for call signaling or call en-
able/inhibit: you can use simple switches instead as shown in Figure 6.

UIO-256 APPLICATION NOTE: GPI OUT - AT THE UIO-256 END, USE THE NORMAL OPEN (NO) CONTACT
FOR GPI OUT CONNECTION, AND USE THE RELAY COMMON CONTACT FOR THE COMMON CONNECTION.
GPI IN - USE THE INPUT HIGH PIN FOR THE GPI IN CONNECTION, AND USE THE COMMON PIN FOR THE
COMMON CONNECTION.
