Distractions With
Alarm Adviser
Adam Barnes – Product
Manager SCADA
Why did the number of alarms increase?
• Automation evolution (including fieldbus) brought more
accessible information per sensor/actuator
• Alarms are easily configurable now (no more wired) -> no
real cost at engineering or operating time to add alarms
• People (e.g. SI’s) tend to believe more is better: nothing can
happen without notice if everything has an attached alarm

Typical observed behavior
● Operator overload leading to
● Over-acknowledgement to keep management
happy and control room quieter
● Inhibiting “noisy alarms”
● Missing important alarms
● Not being able to mitigate in proper time

Operators have too many alarms to manage
What can we do?

First of All – Why
Alarm System Management has become an important operational tool to:
Save time and money – deal with important conditions only
Reduce risk – hardware maintenance, plant operation, incidents
Improve effectiveness of operations – focus on the real issues
