Chapter 4. Front Panel Operation and Menu Structure

Alarm (ALRM) Menu

From the terminal menus you can view a log of system events. To control the types of events logged, a series of filters have been defined for each event source (System, T1/PRI, ISDN, Ethernet, etc.). Any event with a severity greater than, or equal to, the threshold defined in the event logging filter list is logged to the sys- tem event log. Events that do not appear in the event log do not appear in the front panel alarm lists. Therefore, the event logging filters are applied to both the terminal and the front panel menu lists. See “System Event Logging” on page 5-16 for details on setting the thresholds for event logging.

Active Alarms

This menu item displays a list of current alarms reported by the base controller. If no alarms are current, this menu item displays End of List. If there are current alarms, this display includes two lines of text. The top line is the alarm source. The bottom line is the alarm message.

View History

This option displays a time and date-stamped list of the alarms that have occurred in the ATLAS 800PLUS. Some alarm types include -Ato indicate the alarm is active and -Ito indicate the alarm is inactive.

Clear History

This option clears the alarm history log.

When you clear the alarm history log, you cannot retrieve the data.
