The SetAlarmExtendedData() action sets extended data for an alarm. The extended data is additional, user-specified data for the alarm. You can use extended data to integrate with third-party applications. This action is available for the Alarm, AlarmStateChange, AlarmSeverityChange, and AlarmExtendedDataChange trigger messages only.
