Project-specific notification classes can be defined in addition to predefined ones. Alarm classes 7...16 are
intended for this purpose. The associated calculation of a notification class number is identical to
calculation of predefined notification class numbers.
Customized alarms can be engineered in Desigo PX. In this case, the value for a notification class number
can be defined without restrictions.
Priority [Prio]
This defines the alarm priority on the basis of which alarm and system events are to be transmitted to the
receivers. Every transition can be described individually with this BACnet property, data type ARRAY of
INTEGERS [TO_OFFNORMAL; TO_FAULT; TO_NORMAL]. Priority levels can range in value from 0 to 255.
The lower the value, the higher the priority. In Desigo only priorities 1 to 9 are used.
Alarmfunction [AlmFnct]
Alarm function types: Simple, Basic or Extended. [AlmFnct] is only supported by Desigo PX.
Destination list [RecpList]
The configured (permanent) alarm recipients, the week days, and the time window in which the alarm
recipient is operated, are entered here. [RecpList] is equivalent to the standard BACnet property
Recipient_List.
Destination list [DestLi]
This is where the configured (permanent) alarm receivers are entered, together with the days of the week
and the time-window in which the alarm receiver is operated. [DestLi] is only supported by Desigo PX.
