Alarm Acknowledgment Scenarios
Here is an example of a simple alarm acknowledgment scenario.
1. An alarm has an initial status of normal (green).
2. A critical error occurs, causing the alarm’s current, latched and acknowledgment states to change from green to red.
3. After a few seconds, an operator acknowledges the alarm, which changes the acknowledgment state back to green. Other operators can see that the error is still present, but that someone is working on it.
4. If the problem is fixed before the acknowledgment period expires, the alarm’s current state reverts to green (the acknowledgment state remains green).
5. If the problem is not fixed before the acknowledgment period expires, the acknowledgment state reverts to red.
Here is an example of a recurring alarm acknowledgment scenario.
1. As in the previous scenario, the alarm is acknowledged and the acknowledgment state reverts to green.
2. If the problem is not fixed before the acknowledgment period expires, the acknowledgment state reverts to red, which triggers a second alarm (that gets logged) with a note that the issue has now escalated once.
3. A scripted action might, at this point, send an SMS message to a supervisor.
