[. . . ] SlOl is for , System A S201, is for System B. For Clear-Com, install a shorting jumper. For RTS or Audiocom, leave the shorting jumper off or connected to one pin only. Note: As an option, remote switches may be used to independently enablelinhibit call signalling on System A and System B. (See "SSA324 Rear Panel Connections, Remote Call Signal EnablefInhibit Control. ") To use this option on System A do not install the SlOl jumper. To use this option on System B do not install the S102 shorting jumper. Set the W1 jumpers on the A1 Option Card. The W1 jumpers interconnect the call signals between System Aland System B. To interconnect System A and System B, install shorting jumpers on pins 1-2 and 3-4. If you do not want call signal exchange, remove the jumpers or connect to one pin only. Set the W103 and W203 jumpers on the SSA324 circuit board. W103 and W203 must be set for the correct type of intercom system. W103 is for System A; W203, for System B. For Clear-Com, install a shorting jumper on pins 2-3. For RTS or Audiocom, install it on pins 1-2. Connect the A1 Option Card to the SSA324 circuit board using the supplied cables: a. Connect 53 on the option card to 54 on the SSA324 circuit board. Connect J4 on the option card to J5 on the SSA324 circuit board. Connect 58 on the option card to 53 on the SSA324 circuit board. c. 6. Mount the A1 Option Card. Refer to figure 1 and mount the option card as shown using the supplied hardware. 7. Reassemble the SSA324. Figure 1 CALL SIGNALLING CONNECTIONS Connector pin usage is summarized in tables 1-3. For further information regarding audio connections and operation, refer to the SSA324 User Manual. KEYING INPUT FROM TRANSCEIVER OR OTHER EXTERNAL DEVICE The keying inputs operate by detecting an external switch contact closure. The keying inputs can be connected to the carrier detect or squelch detect output (on transceivers so equipped) to trigger a call signal when 'the transceiver is receiving. [. . . ] For remote enabletinhibit of System B call signalling, connect a switch between 5103 pins 25 and 12. For Audiocom or RTS: Closing the switch will inhibit call signalling. Opening the switch will enable call signalling. For Clear-Com: Opening the switch will inhibit call signalling. [. . . ]
