Class object. In addition, each recipient has a FromTime and ToTime, which specify
a window, on those days of the week, during which the recipient is viable. If an event
that uses a notification class object occurs and the day is one of the days of the
week that is valid for a given recipient and the time is within the window specified for
the recipient, then the recipient shall be sent a notification. Recipients may be
further qualified, as applicable, by any combination of the three event transitions TO
OFF-NORMAL, TO FAULT, or TO NORMAL.
The recipient also defines the device to receive the notification and a process within
the device. Processes are identified by numeric handles that are only meaningful to
the recipient device. The administration of these handles is a local matter. The
recipient device may be specified by either its unique Device Object Identifier or its
BACnet Address. In the latter case, a specific node address, a multicast address, or
a broadcast address may be used. The recipient further specifies whether the
notification shall be sent using a confirmed or unconfirmed event notification.
How the notification class assignment is handled in CARE: please see the following

priority settings. The following table shows the alarm and event priorities
