An Alarm is an indication that there is a system
operating limit that is being exceeded and that a
Fault may be imminent (not all ongoing alarms
result in a fault) or to provide an indication that an
operator error has occurred. An Alarm may be
associated with an output terminal to notify the
operator of the condition remotely, close a contact,
or to engage a brake. At the least, an Alarm will
cause an alarm code to appear on the EOI display
