  • Alarm Notification Accepted, call-for-service created
  • Alarm Notification Reject due to invalid alarm location address or invalid event type
• Bi-directional update of other events between an alarm monitoring company and a PSAP
  • Requests for cancellation by the alarm monitoring company
  • Updates concerning key-holder information by the alarm monitoring company
