Noncritical Alarm
This alarm occurs if one or more enclosure elements have failed or operate outside of their
specifications. These failures do not affect normal enclosure operations. If additional

from escalating to a critical condition.
This alarm establishes the following conditions:
■
Unrecoverable and critical alarms take precedence over this alarm.
■
Maintains precedence over informational alarms.

corrective action before an element failure occurs.
This alarm establishes the following conditions:
■
All other alarms take precedence over this alarm
■
Sounds the informational alarm tone (one short beep that repeats every 2 seconds)
