Responding to Alarms
When an alarm comes into the system, it is your responsibility to clear that
alarm. When an alarm is cleared, the following things happen:
· The information associated with that alarm is removed from the monitor.
· The monitor returns to whatever action it was performing prior to the
alarm. For example, it will resume whatever Pattern was running at the
time the alarm came in.
· Any of the outputs that were triggered as a result of the alarm are
restored to their original condition (unless the output was configured to
remain in its changed state).
Your System Administrator decided the alarm clearance method when the
Activity was initially defined. This is called the alarm’s reset mode. Alarms
can have three different reset modes:
· They can clear automatically after a certain amount of time has elapsed.
· They can be cleared manually by an operator via the T
OUCH TRACKER.
