Group Escalations

Also known as alarm shower suppression

Overview

When many alarms are triggered within a short time, this can lead to a flood of notifications. To avoid this, alarms can be combined within an escalation. In this process, several incoming alarms are grouped into a single escalation message—depending on individually defined conditions. In addition, certain alarm tags can be excluded from the combination so that they are still escalated individually.

Procedure

1. Click on Engineering [A]

2. Click on Escalation [B]

   ▷ The overview of the escalation configurations opens.

3. Click on [D]

   ▷ The Combine Alarms window [D1] opens.

4. Activate the switch [D2] to enable the combining of alarms.

5. Under [D3], enter the time period in seconds within which the alarms must occur to be combined.

6. Under [D4], enter the minimum number of alarms that must occur within the defined time period for them to be combined.

7. Under [D5], select the alarm tags that are to be excluded from the combination (e.g., High Prio).

8. Click on Save [D6] to apply the changes.

Example

Conditions:

• Time period: 10 seconds

• Minimum number: 5 alarms

Scenario 1: Within 8 seconds, 5 alarms are triggered without excluded tags → The alarms are combined and sent as a single escalation message.

Scenario 2: Within 10 seconds, 4 alarms are triggered → No combination, 4 individual escalation messages are sent.

Scenario 3: Within 10 seconds, 7 alarms are triggered, of which 2 have the tag High Prio (excluded) → The 5 remaining alarms are combined, the 2 High Prio alarms are escalated individually.
