An extension of the Alarm model where previous states of Alarms will be retained until they are acknowledged and/or confirmed.

Usage Considerations

  • Domains, where all transition in an alarm model must be individually responded to by one or more operators.
  • Safety critical systems that require that all Alarms be acknowledged even if it the original problem goes away and the Alarm returns to the inactive state.
