Alarm Management webinars

30 May 2018

MAC Solutions are presenting a series of Alarm Management webinars during 2018, and this webinar (Alarm System Performance KPI's) will take place on 13th June from 12:30 to 13:30 BST.

Alarm system performance KPIs have been around since the release of EEMUA 191.

The Bransby & Jenkinson survey performed in 1998 concluded that one alarm per ten minutes was considered very likely to be acceptable. Since then, these KPIs have been starting to live their own lives. One alarm per ten minutes was quickly translated to six alarms per hour. ISA 18.2 upon its release in 2009 stated that about 150 alarms per day would be acceptable as a KPI. IEC 62682 in 2014 states about 144 alarms per day would be a good target value. ISA 18.2 - 2016 omitted this KPI, along with two other KPIs. This paper explains why and why one alarm per time frame cannot be translated into so many alarms per hour.
