Alarm Classification – Not all alarms are created equal!
Recording Date: December 2016
Alarm classification is a process for grouping alarms that have a common set of requirements for areas like training, maintenance, testing, management of change, and reporting. It could, for example be used to identify Safety (Related) alarms that are used for functional safety purposes. Classification is also a required output of alarm rationalization per the ISA-18.2 and IEC 62682 alarm management standards. Despite this, many alarm management projects ignore classification or misinterpret what it is to be used for (it’s not the same as alarm priority or alarm type). Additionally the usage and benefit of Highly Managed Alarms (HMA) is not well understood.
This presentation will review the purpose of alarm classification, how to define alarm classes, and how to assign alarms to classes. It will also discuss the origin and purpose of Highly Managed Alarms, and their associated requirements. Lastly it will present application examples of classification (including “Safety Alarms”) and the benefits that can be realized by end users.
