Honeywell products that support effective alarm strategies
Consider the following Honeywell products when planning your alarm system and strategies
for dealing with abnormal situations.
Alarm Configuration Manager
Alarm Configuration Manager (ACM) is a product that is separate but complementary to
Experion. The key feature of ACM is its capacity for “holding” designed alarm settings as the
master alarm database, and through audit and enforcement, providing a “safety net” to ensure
that changes are temporary and that the engineered alarm configuration can always be
restored.
With ACM, settings like alarm trip points, priorities, and the disable status can be driven by
planned equipment operating modes. ACM also provides tools that support work processes
for alarm rationalization and maintenance.
Experion Dynamic Alarm Suppression
Experion Dynamic Alarm Suppression (DAS) is ideal for reducing excessive alarms arising
from unplanned compound events like equipment trips. It provides additional capability and
convenience above and beyond the current mechanisms of controller logic. Although DAS
can be applied to suppress alarms from planned equipment outages, ACM provides a more
complete solution for planned outages.
Experion alarm or alert shelving
Experion alarm or alert shelving allows operators to temporarily remove alarms or alerts from
the main display when they are nuisance or extraneous alarms or alerts that are not filtered out
by other mechanisms.
Other Experion functionality
Within Experion there is a range of other functionality that enables operators to deal with
excessive or extraneous alarms. For example, operators can temporarily disable alarms. There
is also an Experion alarm configuration option that, when enabled, allows operators at a
specified security level to temporarily suppress the audible annunciation of non-urgent alarms.
To help deal with alarm bursts and floods, operators can also use the Alarm Tracker pane on
the Experion Alarm Summary. Alarm Tracker is an Experion license option that provides a
graphical, time- and asset-based view of alarms. By making it easier for operators to identify
“clusters” of alarms on assets within an operator’s scope of responsibility, an alarm tracker
helps operators to respond more quickly to excessive process alarms.
While such functionality provides a good basis for dealing with situations that can lead to
excessive alarms, ACM, DAS and alarm shelving provide extra capability that can
significantly reduce the number of excessive alarms that have no operational relevance.
