• Operating Notes for ADAM, ADAM CS and Zeus Intercom Systems

  17
  • 1. 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.

    17
  • 2. Key assignment, party line assignment, etc. is the same as for any other intercom port.
