The server-client nature to the FSA system architecture provides easy integration of CAD
dispatch consoles. If CAD is present, it can serve as the primary user interface by
communicating commands to the FSA Server. To accomplish this, the CAD system will
use either the existing Model 26 CAD interface protocol or Zetron’s new XML-based
protocol.
Whether the dispatcher instructions are input through the CAD console or the FSA
Console, once the user inputs are made, the FSA Server handles communications out to
the individual fire stations to ensure that all messages sent are successfully received.
Because the FSA Server is capable of monitoring system integrity and able to provide
failure indications, it is NFPA 1221 compliant.
The FSA Server can both notify and be acknowledged by up to 255 fire station units
(Model 6203 or Model 6204) almost simultaneously. Once the FSA Server receives the
“OK to talk” message from the Station Transponder Units (sent after all the alert tones
