10. Create Derived Alarms for Events That Don't Happen As Scheduled

A Derived Alarm can even tell you when events DON'T happen. Why is this useful?

Let's suppose a generator self-test is supposed to happen every Tuesday at 3 A.M. You don't want to be notified every time a successful self-test happens - that's a nuisance alarm that your staff will ignore, and no one will notice if the weekly notification doesn't come.

But you can create a Derived Alarm that will be triggered only when the self-test doesn't happen on schedule - so you get the most useful information when you need it.
