Item | Description |
Name | The name of the alarm |
Severity | Defines the severity level of the alarm, which will be included in the alarm email and alarm status page. |
Asset Alarm Type | For EBITrack 400, specify the asset health alarm type. |
Asset | The asset to alarm on. |
Site | The site on which the asset is located. |
Health Score | The asset channel showing the health score – note that this channel will be created and populated automatically by Centrix for EBITrack 400 assets. |
Threshold | The alarm threshold – if the health score drops below this an alarm will be raised. |
Debounce Period | If the health score rises above the threshold (after dropping below it) within this period of time, an alarm will not be raised. |
Suppression | The suppression periods for the alarm. If duplicate or additional alarms are raised immediately after this alarm is raised, within the specified period, they will be suppressed. This can be used to prevent multiple alarms being raised for the same fault event. |
Emails | The emails of individual alarm recipients. Can be used in addition to alarm labels. |
Labels | The label applied to the alarm. Can be considered as a sort of mailing list. See the section on alarm labels below. |
Subscribed | If unchecked, alarms can be raised but the alarm emails won’t be sent out, requiring the user to monitor the alarm status page instead. |
...
Once all of these items have been completed, use the Save Alarm control to save or update the alarm.

Alarm labels can be considered as a mailing list, typically used where a team of people are monitoring a group of assets. When an alarm label is created, a list of emails can be added to it, so that when an alarm with this label is raised all the recipients will receive an email. Alarm labels can be created and edited by navigating to the Alarm Labels page via the Centrix menu in the top left of the front-end.

Viewing the current and historical status of alarms
The current and historical status of alarms can be monitored in real-time by navigating to the Alarm Status page via the Centrix menu in the top left of the Centrix front-end.
...
By default, this page lists all active alarms. Alarms which have just been raised have a red exclamation icon next to them, and alarms which have been raised in the past but not yet acknowledged have a blue icon. The list of alarms can be filtered by type, site, and severity using the controls on the left of the page, with an option to include alarms which are not active.
Clicking on an alarm raise report will open a small menu below it (as illustrated above). From here you can navigate to the asset status page, the alarm raise history, or alarm raise report using the relevant control. Once the alarm has been investigated and dealt with, clicking the Clear Alarm control will remove the alarm raise from this page.
Viewing the current and historical status of an asset
The current and historical status of an asset can be investigated and viewed by clicking on the asset in the asset list page.
...
When the asset view page is first opened, the asset playback tab is shown by default.
...
For EBITrack 400 devices, the most recent track occupation is shown. Using the time and navigation control above the chart, occupations can be flicked through by date, alarm raise, event, or tag. In the image above we can see that this occupation has been given two tags by Centrix: a high current and unstable current tag, indicating that this occupation is anomalous. When occupations receive tags like this, the health score for the associated asset drops.
...
Beneath the occupation chart, the most recent value recorded on each asset channel is displayed. These values will be updated as the time and navigation control at the top of the page is moved.
Configuration parameters associated with the asset are listed in the asset details table at the bottom.
...
The next tab on the asset page is the alarm tab. Here all the alarms associated with this asset are shown in the alarms table. If there are other alarm types available for this asset which have not yet been created, they are listed in the missed asset alarms table. By clicking the checkmark next to the missing alarm entries and using the Generate Selected Alarms control, these alarms can be automatically generated.
...
Finally, by clicking on the health tab, a time-series chart showing the historical health score is shown, allowing the user to review the health of the asset over time.
Generating reports
The reporting tool in Centrix can be accessed via the Centrix menu in the top left of the Centrix front-end.
...
Several types of report can be generated to summarise historical data in Centrix. For EBITrack 400 assets, the following reports may be useful.
Report Type | Description |
Alarm Raise Times | A report which groups alarm raises by day, week, or month. Can be used to spot patterns in asset condition. |
Alarm Raise Count | Lists alarm raises per asset over a period of time. Can be used to see which assets have historically suffered poor performance and rank assets for triage. |
Analogue Histogram | Can be used to look at the distribution of analogue samples, for example to identify anomalous data on the non-current channels of the device. |
Raw Analogue Events | Can be used to export raw data for analysis in Excel. |
If additional reports would be useful, please notify the Centrix team so that they can be included in a future release.
