[. . . ] Connect a separate Clear-Com party line to the J1B connector (System B). The SSA-424 features internal CD isolation. You can therefore connect the SSA-424 to powered Clear-Com cables, and it will not draw any power from the Clear-Com system. 2 On the SSA-424 front panel, set the System A and System B 2W CHAN SEL switches to position 2. If the System A or System B hybrid will not be used, set its 2W CHAN SEL switch to either OFF position. 1 Use the J1A connector on the back of the SSA424 to connect one 2-wire line to the System A hybrid. Use the J1B connector to connect a second 2-wire line to the System B hybrid. The pin configuration for the J1A and J1B connectors depends on whether you are connecting a balanced or unbalanced 2-wire line: Balanced Configuration Pin 1: Pin 2: Pin 3: No connection Balanced Audio + Input/Output Balanced Audio - Input/Output There are two possible configurations for unbalanced connection: Unbalanced Configuraton 1 Pin 1: Pin 2: Pin 3: Audio Common Audio + Input/Output No connection Unbalanced Configuration 2 Pin 1: Pin 2: Pin 3: Audio Common No connection Audio + Input/Output 2 On the SSA-424 front panel, set the CHAN SEL switches as follows: · Balanced Configuration: set the CHAN SEL switches to the BAL position · Unbalanced Configuration 1: set the CHAN · SEL switches to position 1. Unbalanced Configuration 2: set the CHAN SEL switches to position 2. If the System A or System B hybrid will not be used, set its 2W CHAN SEL switch to either OFF position. 10 SSA-424 USER MANUAL 2. 5 2. 5. 1 4-WIRE CALL SIGNAL CONNECTIONS These connections require the call signal option.

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 Universal Input/Output Frame, you can also use that for connections (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, the example uses GPI outputs #1 and #2 and GPI input #1. You may substitute other GPI inputs and outputs. IMPORTANT NOTE FOR AZEDIT USERS: AZedit version 1. 06 includes a feature which allows you to invert the action of the GPI outputs. By default, these outputs are set to duplicate the actio of the RTS FR9528 Relay Frame accessory. This is the correct setting for use with the SSA-424. To check the AZedit setting, select Intercom Configuration in the Options menu. Click on the Options tab, then verify that Configure onboard GPI outputs in FR9528 mode is selected.

[. . . ] Configuration 2, Switched Full Duplex Mode: Switches from half duplex to full duplex 3-9 seconds after conversation begins on the 4wire line. Stays in full duplex mode until 6090 seconds after conversation ceases. This helps to keep the line quiet during perdiods of no conversation, while permitting natural conversation when people are talking. This is the preferred operating mode for many situations, and par ticularly for fast, closecoordination, team operations. [. . . ]
