SSA-324
System-to-System Interface
The Model SSA-324 is a System to System Adapter (or interface). It interconnects the voice signals between different intercom
systems. In addition, it can optionally interconnect “Calls” or tally signals between systems. Each SSA-324 includes two two-
wire to four-wire converters. The four-wire interface can deliver and accept high level signals. An SSA-324 can also function as
a two-wire to two-wire interface by interconnecting the two individual interfaces
