Alarms notify the operator about plant abnormalities quickly to prompt for action, which is essential for the stability and safety of plant operations.
Alarm System is a human interface that constantly monitors processes and if abnormalities (abnormal conditions and failures) are found, notifies the operator with alarms to prompt for action.
Alarm Management is the continuous management, the standardization and unification of alarm-assisted operational management and techniques.
A good alarm solution must comply with the ISA18.2, the IEC 62682, and the EEMUA#191.
- ISA18.2 : Management of Alarm Systems for the Process Industries
- IEC 62682 : Management of Alarm Systems for the Process Industries
- EEMUA#191 : Alarm Systems : A Guide to Design, Management and Procurement
The alarm system design starts with or based on the hazard and operability (HAZOP) study
(a process safety evaluation technique) and on the alarm system design standards(mentioned above),
and builds production control systems based on the design.
