Overall Alarms
An overall alarm is a type of virtual alarm that indicates the overall condition of a device or
service based on the combined statuses of the constituent alarms for that device or service.
Overall alarms are often generated automatically.
Sub-alarms
A sub-alarm is an alarm that contributes to the status of a higher level virtual alarm. Sub-
alarms can be grouped together, and the group itself can become a sub-alarm of a higher-
level alarm. Each sub-alarm may or may not have the same status as its higher-level alarm. The
effect of a sub-alarm’s contribution is determined by the way in which the higher-level alarm is
configured. A sub-alarm’s contribution to a higher-level alarm can, in some cases, be modified.
Miranda Device Alarms
All Miranda devices in an iControl system automatically generate an overall alarm status that
can be viewed in iC Navigator (the icon beside the device name), in the GSM Alarm Browser
(the Overall sub-alarm inside the folder associated with the device), and on Web pages—any
Web page component that is associated with the device, such as a button or a UMD, can be
configured to display the device’s overall alarm status. The overall alarm status comes from the
device’s hardware or firmware, and is based on the status(es) of one or more sub-alarms
corresponding to specific device parameters.
Miranda Service Alarms
All Miranda services in an iControl system automatically generate an overall alarm status that
can be viewed in iC Navigator, in the GSM Alarm Browser, and on Web pages.
Third Party Alarms
iControl can recognize and display alarms for devices and services from third party companies.
As a minimum, all such devices/services are represented by overall alarms that can be viewed
in iC Navigator, in the GSM Alarm Browser, and on Web pages. In many cases, a broader set of
alarms can also be displayed.
The relationship between alarms in iC Navigator and in the GSM Alarm Browser is shown
below.
