A BACnet EventNotification message contains a Priority field indicating the priority of the event being reported. The Priority values to be used are configured via the
Priority property of the Notification Class object, using the configuration file parameters Pri_to_offnormal, Pri_to_normal and Pri_to_fault, which determine the priorities
to be used respectively for all to-offnormal, to-normal and to-fault transitions reported via the Notification Class object.
Priority Values should be chosen as follows:
Alarm and Event Priority Network Priority
00-63
Life Safety Message
64-127 Critical Equipment Message
128-191 Urgent Message
192-255 Normal Message
Appendix A.7.7. Map Descriptor Example – Set up a Permanent Static Recipient List
A permanent static RecipientList may be configured directly on the FieldServer, eliminating the need for a remote workstation to modify the RecipientList in order to
receive Event Notifications. Using this option makes the RecipientList read-only, i.e. it can then only be modified via the FieldServer config.csv file.
This is done by adding an Event_Receiver section to the config.csv. This section must appear after the definition and all other references to the relevant Notification Class
object.

Notification Class Objects are configured as Map Descriptors. Each Notification Class Object maintains a RecipientList Property which may contain multiple destinations.
Each destination is configured as an Event_Receiver after the relevant Notification Class Object has been configured.

Notification
Class map
descriptor BAC_NC_P1
This section sets up RecipientList entries for the defined Notification Class map
descriptor. It must appear at the end of the configuration, after all other
references to the Notification Class map descriptor.
