A channel number is an ordinal number that identifies a particular channel. All channel numbers must be unique.
Channel numbers are used in:
The order of the assignment of channel numbers can be very important. Depending on the setting for reporting priority (set in Alarmware™ only) it is possible that the order of notifications to destinations will be determined by the order of channel assignment. If reporting priority is set to "Channels" then when more than one channel is in the Unacknowledged Alarm state, alarm reports will be sent to destinations with a priority based on the lowest channel numbers first.
Conversely, when the reporting priority is set to "Destinations" the priority will be based on the order of destinations. Thus, when there are multiple channels in alarm, the first reports go to those linked destinations with the lowest destination number first.
