Abstract
Alarm annunciators are a vital tool in safety management. The need for functional safety assessment continuously pushes the technical performance of alarm annunciators upwards. Operator involvement puts a limit on reliability of safety functions but may be beneficial in managing complex demands.
This paper explores the realistic boundaries of performance of alarm annunciators and operators in safety-critical applications.
