When a
system event
occurs, it is routed to the System Event Channel Group
(Communicator\System Event Reporting\System Channels). The Channel Group will forward
the event to each of the Channels it co
ntains. If the event is on the Channel’s Event List, the
Channel will attempt to send the event to the Channel’s destination.
Example
System
Event
If a
sensor or area event is generated
, then the event is sent to the Channel Group
specified (Area
– Channel Group) in the lowest area the sensor belongs to. The Channel
Group forwards the event to each of the Channels it contains. Each Channel checks its Event
List to determine if the event should be sent.

Channels 1 and 2 will attempt to send the event as AC Fail is on the
corresponding Event List. Back up channels 4 and 5 will also attempt
to send the event if they are used.
Channel 3 will NOT send the event as Event List 2 does not include
AC Fail events.
