Alarm Propagation to the Device Group. If alarm propagation is enabled, the highest severity
unacknowledged alarm status among the devices in the Device Group is indicated by a small alarm bell
to the left of the Device Group name in the Component Tree. When a Device Group has been contracted
so that its list of devices is hidden, the Device Group alarm icon indicates whether alarms have
occurred on any of the devices within the group, and how serious those alarms are.
Alarm propagation can be enabled or disable per device, through the Right-Click Pop-Up menu.
●
Disabling alarm propagation for a device means that device’s alarm status will not be factored into
the alarm status for the Device Group. This lets you base alarm propagation at the device group
level on a subset of critical devices while ignoring less critical devices.
Devices with alarm propagation disabled show an “X” through the alarm icon. However, the color of
the alarm icon still indicates the correct alarm status for the alarm.
●
You can also disable alarm propagation for the Device Group, which results in an “X” over the alarm
icon. However, there is no higher level for alarm status propagation, so this has no real meaning.
The color of the alarm icon will still reflect the worst alarm status of those devices within the Device
Group that have alarm propagation enabled.
Viewing Device Status Information
When you select a device group in the Component Tree, the panel on the right displays a summary
status of the devices in the selected device group (see
Figure 10 ).
