External horn or siren
If there is a possibility that users may not hear a Station buzzer/speaker, you should consider
installing one or more horns or sirens.
You can configure up to fivealarm notification points—one each for Critical, Urgent, High,
Low or Any alarm priority—to control horns or sirens. For example, you could use the
Urgent point to control a horn, and use the Any point to control a buzzer.
Alarm groups
Alarm groups provide you with an alternative way of viewing alarms, which is not related to
your asset model. For example, you could create an alarm group to monitor alarms on all
electrical motors in your plant, regardless of their locations within the asset model. Unless
stated otherwise, the configuration and usage of system alarm groups is the same as alarm
groups. However, system alarm groups can only include system points and other system
alarm groups.
Alarm groups provide the following major benefits:
n
They provide additional filtering capabilities in the Alarm Summary or System Status
display for system alarm groups.
n
They provide aggregate alarming—that is, at each level of an alarm group, you can
see the number of alarms that exist at that level.
n
They allow you to include aggregate alarming parameters in custom displays, so that
operators can quickly see how many alarms there are in each section of the plant.
n
System Alarm Groups can be used to create a hierarchy of dashboards for the System
Status display. For more information, see “Creating a dashboard hierarchy for the
System Status display” in the HMIWeb Display Building Guide.
For more information about alarm groups, see the “Alarm Groups and Aggregate Alarming”
section of the Station Configuration Guide.
Alarm trackers
Alarm trackers provide a graphical, time-based view of alarms on assets within an operator’s
scope of responsibility. An alarm tracker is displayed in a pane on the Experion Alarm
Summary and provides a convenient way of viewing “clusters” of alarms on individual assets.
By grouping alarms in this way, an alarm tracker helps operators to respond more quickly to
alarms in abnormal situations like alarm floods.
Alarm Tracker is an Experion license option.
Best practice recommendations
If you want to implement alarm trackers at your site, it is strongly recommended that:
