Alarms property page
During operation, the RadaScan system produces an event audit trail in the
form of alarms from its various constituent components. These range in
increasing order of severity from: Information, Warning, and Error to Fatal. As
these alarms are received from the sensor, the console application lists them
within the Alarms page tab of the property sheet.
To assist with quick recognition of the various alarm types, a colour coding
scheme is employed. The triangular and square symbols used to represent the
start and stop points of each alarm condition are represented in three colours
to indicate their severity:
• Information
Grey
• Warning
Orange
• Fatal and Error Red
As an alarm condition occurs, its entry is appended by a Start symbol in the
relevant severity colour. When the condition is resolved, the entry is appended
with a Stop symbol.
The Pause symbol is displayed in the event of a single non-persistent incident
The Alarms page offers two key features to assist in the display of applicable
alarms. These are the Alarm filter and the Alarm History.
Using the alarm filter
This allows you to choose which types of alarms (of the four categories) to
display within the Alarms page. As standard the filter is activated with only the
'Information' alarms un-ticked to conceal them. To use the alarms filter:
1 View the Alarms page within the Property sheet (in the lower right corner).
2 Click the right side of the two-part filter button. A drop down list will be
displayed showing the four types of reports/alarms.
3 Click on each type of alarm to check/uncheck them as necessary
- Note: Alarm types that are ticked are shown in the alarms list,
un-ticked items are hidden.
4 To enable/disable the filter, click the left side of
the two-part filter button. The filter is active
whenever the right side of the filter button is
'pressed in'.
Alarms page
- Lists any messages received from the various component units
of the RadaScan sensor. These are classified into four types of alarm which are,
in increasing order of severity:
•
Information
- grey symbols
•
Warning
- orange symbols
•
Error
- red symbols
•
Fatal
- red symbols
A
filter
is available to
suppress the display of
particular alarm types.
As standard, the filter
is activated and the
Information messages
are hidden from the
list.
Deleting alarms from
the current list will
move the alarms to the
Historic list. Deleting
them from the
Historic
list will discard them
permanently.
The arrow symbol indicates the Start
of an entry that persists, while the
square symbol indicates the end of
an entry. The pause symbol indicates
an entry that does not persist.
