A properly managed alarm system has become an integral and critical part of any production and process facility. EEMUA 191 since it was first published in 1999 became the de facto guideline to which industry looked for guidance and good practise on alarm management and alarm management systems. Today, we have a set of standards such as IEC 62682 and in the UK - BS 62682.

To establish a system based on these standards and guidelines or merely ascertain if a current system is working effectively and within the KPI’s set out in these regulatory documents, alarm data must be continuously collected and analysed. With many disparate sources of alarm data from multiple control system vendors, just collecting data can be a challenge in itself.

The ProcessVue Suite of software has been developed with the benefit of over 40 years’ experience in alarm management systems. The architecture has been designed to allow interfacing with virtually any control system, bringing all data into a standard configurable format, for simple Sequence of Event display, high level Key Performance Indicator reporting and analysis and Master Alarm Database (MADb) for rationalisation and documentation.

About us

Founded in 1996, MAC Solutions specialise in helping customers select and source appropriate systems to leverage their plant control and automation systems. Our solutions collect data securely from these systems and provide analytical and visualisation tools for production, maintenance and business planning.

Why alarm systems should not be exceeding perceptual and cognitive capabilities?

In the General Requirements of the Norwegian’s Petroleum Directorate’s “Principle for alarm system design”, YA-711 of February 2001, it is specified that the alarm system shall be explicitly designed to take into account the human factors and limitations. “The design should ensure that the alarm system remains usable in all process conditions, by ensuring that unacceptable demands are not placed on operators by exceeding their perceptual and cognitive capabilities.”

These General Requirements were created based upon investigations and findings which led to the EEMUA 191 Guidelines. ANSI/ISA 18.2 and IEC 62682 also recommend taking into account the ability of the operator to carry out all his functions related to the alarm system. If you want to design an adequate alarm system or if you want to improve an existing one, it is mandatory to consider the person who will be responsible for responding to alarms annunciated and understand that this person, as any human being, has limitations in the perceptual and cognitive processing of the information presented. This paper will try to explain this perceptual and cognitive processing, its limitations and present some of the possible solutions.
