Use standard 9-pin or RJ-11 keypanel cables. Connect from one port of your intercom system to J2A or J3A (System A connection) on the back of the SSA-424A. Connect from another port to J2B or J3B (System B connection).92. On the SSA-424A front panel, set the 4W LEVEL REF SEL switches to the +8 dB position.9Audio Connections for the Other 4-wire Communications Systems91. Construct 9-pin or RJ-11 cables to connect from the 4-wire system to the SSA-424A. To connect to the System A hybrid, use either J2A or J3A; for the System B hybrid, use either J2B or J3B. Pin connections are as follows:92. On the SSA-424A front panel, set the 4W LEVEL REF SEL switches to the position which most closely matches the audio input and output levels of your 4-wire system. If you don’t know the levels, select the +8 dB position for now.10FIGURE 2. Rack Mount Configurations102-Wire Audio Connections10RTS TW Audio Connections101. Use standard TW intercom cables.

On the SSA-424A front panel: For System A and System B, set the 2W CHAN SEL switch to the appropriate position. To interface to TW channel 1 select position 1; for TW channel 2, select position 2.11FIGURE 3. Using a TW-5W to connect to two TW channels to the SSA-424A11Audiocom Audio Connection111.

Connect one Clear-Com party line to the J1A connector on the back of the SSA-424A (System A). Connect a separate Clear- Com party line to the J1B connector (System B).112. On the SSA-424A front panel, set the System A and System B 2W CHAN SEL switches to position 2.11Other 2-wire Audio Connection111. 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...112. On the SSA-424A front panel, set the CHAN SEL switches as follows:124-Wire Call Signal Connections12Call Signal Connection for ADAM, ADAM CS, and Zeus12FIGURE 5.

Attach the power pack to the SSA-424A and apply power to all components. Confirm the power indicator is lit on the SSA-424A front panel.172. Use the level adjust trimmers (Figure 8) to fine tune the listen levels.17FIGURE 8. Location of level adjust trimmers17Operating Notes for ADAM, ADAM CS and Zeus Intercom Systems171. In AZedit use port alpha setup to name each 4-wire intercom port that is connected to the SSA-424A. Choose names which help indicate which 2-wire line is being interfaced.172. Key assignment, party line assignment, etc. is the same as for any other intercom port.173. Optional call signal output using the GPI: you can assign the GPI output to a talk or listen key, then activate that key to generate a call signal.174. Optional call signal input using the GPI185. Optional call enable control. If you connected a GPI Output for use as a call enable control, you can assign that GPI output ...186. Send your changes to the intercom system. This completes any required programming for ADAM, ADAM CS, or Zeus intercom system.18Internal Access191. Remove six screws from the back cover.192. Remove the top cover. This provides access to all internal adjustments.193. For option card installation, slide the circuit board out toward the back to remove it from the bottom cover.19FIGURE 1. Location of screws for disassembly.19FIGURE 2. Locations of internal controls19Mode Dip Switch Settings19TABLE 1. Mode DIP Switch Settings19Call Signal Option Card Installation201. Disassemble the SSA-424A as previously described.202. Assemble the standoffs to the circuit board using the supplied screws and lock-washers.203. Connect the supplied power cable from J8 on the option card to J303 on the main board of the SSA-424A.204. Insert the connectors on the option card into the connectors on the main board.205. Use the remaining screws and lock-washers to secure the standoffs to the main board.206. Reassemble the SSA-424A.20FIGURE 3.
