Alarms and warnings handling

End-to-end alarm flow.

Boomerang monitors measuring point readings.

When a value crosses a limit, the system raises a warning or an alarm.

Key concepts

• Limits define when alarms and warnings trigger.

  • See Alarm limits.

• Alarm Filter reduces noise by requiring consecutive out-of-limit readings.

  • See Alarm filter.

In this section, “alarm” means alarms and warnings unless stated otherwise.

1

Alarm is triggered

An alarm becomes active when limit and filter conditions are met.

Active alarms are shown in the UI.

See Alarm presentation.

2

Alarm is delivered

The system notifies one or more users using configured channels.

See Alarm delivery.

3

Investigate and correct

Use the alarm list and object view to identify the cause.

Typical outcomes:

• the measured value returns to the normal range

• communication with the measuring point is restored

Also do preventive actions to avoid recurring alarms.

4

Sign (close) the alarm

Alarms remain active until a user signs them.

See Alarm signing.

Warnings close automatically when the warning condition disappears.

If you sign while the condition still exists, the alarm can trigger again.
