This article outlines everything you need to know about alarm states.
What is Alarm States?
Alarm states refers to the alarm system utilised by Measured Data alarms.
Note: For now, alarm states only applies to Measured Data alarms triggered by RMS and Temperature, however, the feature will soon be implemented for condition alarms triggered by the AI Output chart.
Under alarm states, equipment is considered as existing in one of two states: 'Normal', and 'Alarm'.
When a sample is received above an equipment's alarm value, an alarm is triggered, and the state of the equipment shifts to 'Alarm'. The equipment will remain in this state until a sample is received below the reset value, and is within normal range, and thus the state of the equipment will shift back to 'Normal'.
When the state of the asset changes, two things will happen:
- You will receive a notification alerting you to the transition. This requires acknowledgement.
- An alarm event will be generated and appear on the Alarm List Page.
To view the alarm event and all other Measured Data Alarms on the Alarm List Page, click the selector at the top of the page. This allows you to switch between Condition Alarms and Measured Data Alarms.
On the Alarm List Page, the event will appear with an "event status".
This indicates to you the progression of the event and how it has been addressed. Possible statuses include:
- New: status upon initial alarm generation
- Acknowledged: status once the notification has been acknowledged
- Valid: the alarm has been acknowledged as valid - your team found something wrong.
- Invalid: the alarm has been acknowledged as invalid - a 'false alarm'. No cause for the alarm was found.
- Closed: the event has been resolved.
It's only once the event has been acknowledged that you will be provided with the option to set the alarm as 'Valid' or 'Invalid' and provide a reason why. These pages will look as follows:

Setting Event Status as Invalid:
On the Alarm List Page for Measured Data Alarms, you'll also find the columns 'Description', and 'Threshold'.
- Description outlines which condition changed and how. For example, “RMS Threshold Exceeded”.
- Threshold outlines why the asset transitioned to another state. For example, “The RMS value of 6.6 was greater than the alarm value of 5.0".
