18. ALARMS
The S3C Case Control monitors control components and
system conditions and performance and detects conditions
that result in alarm notification to the user and appropri-
ate risk mitigating controller reaction. Alarm notification
appears locally on the Display Module (DM) display and is
published via communication both via MODBUS and BAC-
net. Any one or all of these media may be used as a means
of notification as well as real-time viewing of active alarm
conditions.
Multiple alarm conditions can exist simultaneously and
may share a common root cause such as component fault
or transgression of a user programmed alarm threshold.
Some alarm conditions are self-clearing while others are
persistent and require user intervention to clear the alarm
condition and the subsequent notification. All alarm events
are retained in an alarm history to aid in troubleshooting
the system and occurrence of self-clearing alarms that are
no longer active.
