DESCRIPTION The A1 Option Card installs in a Model SSA324 System-to-System Adapter. It converts RTS (either "TW or Series 800), Clear-Com or Audiocom call signal input into a relay contact output which can be used to key a transceiver or other device. And, it converts a contact closure input from the external device back into an RTS, Clear-Com or Audiocom call signal. The A1 Option Card also converts call signals between RTS, Audiocom and Clear-Com intercom systems. Applications include interfacing to 4-wire telephone or microwave circuits, to 2way radios, to an RTS 4-wire matrix intercom system, or simply activating a call indicator light. INSTALLATION INSTRUCTIONS 1. Disassemble the SSA324. On the back panel, remove the six screws securing the top and bottom covers. Grasp the back panel and slide the back panel and circuit board assembly out of the bottom cover. The SlOl and S201 shorting jumpers must be set for the correct type of intercom system. 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. 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. Connect the A1 Option Card to the SSA324 circuit board using the supplied cables: a. 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. [. . . ] Closing the switch will enable call signalling. System B Note: For this application the S 102 jumper should not be installed. For remote enabletinhibit of System B call signalling, connect a switch between 5103 pins 25 and 12.
