* @section DESCRIPTION
*
* The GetAlarmSummary service is used by a client BACnet-user
* to obtain a summary of "active alarms." The term "active alarm" refers
* to BACnet standard objects that have an Event_State property whose value
* is not equal to NORMAL and a Notify_Type property whose value is ALARM.
* The GetEnrollmentSummary service provides a more sophisticated approach
* with various kinds of filters
