SHIPPING TO THE MANUFACTURER All shipments of product should be made via UPS Ground, prepaid (you may request from Factory Service a different shipment method). Any shipment upgrades will be paid by the customer. The equipment should be shipped in the original packing carton. [. . . ] Connect a separate ClearCom party line to the J1B connector (System B). FIGURE 3. Using a TW-5W to connect to two TW channels to the SSA-424A Audiocom Audio Connection 1. NOTE: The SSA-424A features internal DC isolation. You can therefore connect the SSA-424A to powered Clear-Com cables, and it will not draw any power from the Clear-Com system. 2. You can directly connect standard Audio 1-channel cables. Connect one Audiocom channel to the J1A connector on the back of the SSA-424A (System A). Connect a second Audiocom channel to the J1B connector (System B). If your Audiocom system uses 2-channel cables, use a JB-2 Junction Box to split the channels (Figure 4) On the SSA-424A front panel, set the System A and System B 2W CHAN SEL switches to position 2. NOTE: If the System A or System B hybrid will not be used, set the 2W CHAN SEL switch to the OFF position and attach a dummy load to the TW XLR connector. NOTE: The SSA-424A features internal DC isolation. You can therefore connect the SSA-424A to powered Audiocom cables, and it will not draw any power from the Audiocom system. 2. Other 2-wire Audio Connection 1. On the SSA-424A front panel, set the 2W CHAN SEL switches for System A or System B to the BAL position. Use the J1A connector on the back of the SSA-424A 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 depend on whether you are connecting a balanced or unbalanced 2-wire line, as follows: NOTE: If System A or System B hybrid will not be used, set the 2W CHAN SEL switch to the OFF position and attach a dummy load to the TW XLR connector. LINE 1 J2A LINE 2 LINES 1&2 NOTE: If the System A or System B will not be used, set the 2W CHAN SEL switch to the OFF position and attach a dummy load to the TW XLR connector.

Balanced Configuration Pin 1 Pin 2 Pin 3 No Connection Balanced Audio + Input/Output Balanced Audio - Input/Output If your intercom system is equipped with a UIO-256 (Universal Input/Output) Frame, you can also use that for connections (Table 2 on page 10 and Table 3 on page 10). As an alternative to using the GPI, you can use external components to send and receive call signals as described in "Call Signal Connections for other 4-wire Communications Systems" on page 11. Typical GPI connections are shown in Figure 5 on page 9. The example uses GPI outputs #1 and #2 and GPI Input #1. You may substitute other GPI Input and Outputs. IMPORTANT NOTE FOR AZEDIT USERS: AZedit version 1. 06 or higher includes a feature which allows you to invert the action of the GPI outputs. By default, these output are set to duplicate the action of the RTS FR9528 Relay Frame accessory. This is the correct setting for use with the SSA-424A. 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. ** Termination 300 There are two possible configurations for unbalanced connection: Unbalanced Configuration 1 Pin 1 Pin 2 Pin 3 Audio Common Audio Input/Output No Connection ** Termination 200 Unbalanced Configuration 2 Pin 1 Pin 2 Pin 3 Audio Common No Connection Audio Input/Output ** Termination 200 2. On the SSA-424A front panel, set the CHAN SEL switches as follows: to the BAL position. · Balanced Configuration: set the CHAN SEL switches · Unbalanced Configuration 1: set the CHAN SEL switches to position 1. · Unbalanced Configuration 2: set the CHAN SEL switches to position 2. NOTE: If System A or System B will not be used, set the 2W CHAN SEL switch to the OFF position and attach a dummy load to the TW XLR connector. 4-Wire Call Signal Connections NOTE: These connections require the call signal option. Call Signal Connection for ADAM, ADAM CS, and Zeus You can use the General Purpose Interface (GPI) connector to interface call signals. The pin-out of the connector is the same for all of these intercom systems Table 1 on page 9.

[. . . ] This will open the Edit GPI Input window. · In the Port Alpha list box, select the intercom port that is named in step 1. · In the Key Number box, type 1. This selects key 1 at the intercom you specified in the previous step. · Select Talk Key. · Access keypanel setup, and select the intercom port that is named in step 1. Make sure the setup page, Main is selected. · Assign talk key number 1 to talk to the intercom port that you selected in step C. We also recommend that you assign auto-listen (AL) to the listen key above that talk key. 5. Optional call enable control. [. . . ]
