5.3 View Event Log
In addition to alarms, the AC8 tracks other changes in the Event Log
to assist users with verifying operational and troubleshooting
problems. Events reflect changes in the status of an input that is
defined as an event or the change of state of an output (i.e., manually
forced ON or OFF). Other events may be informational, such as a user
login or an unsuccessful page attempt. The Event Log contains up to
99 records of events, which are added as they occur.
To view the Event Log:
• From the Main Menu, use the arrows ↑↓ to choose View Status,
then press Enter ↵.
• From the View Status Menu, use the arrows ↑↓ to choose View
Event Log, then press Enter ↵ .
5.3.1 Event Log
The Event Log screen displays up to 99 recent events. If the log
contains any event records, the Event Log screen displays details for
each event:
• the event source (for example,
PAGER
or
DEVICE_1
)
• the status of an input or output (
FORCE ON
)
• a brief description of the event (
UNSUCCESSFUL PAGE
or
CONTACT
CLOSED
)
• the date and time the event occurred
Table 9 shows conditions that the event log records for inputs and
outputs and in the panel itself.
If there are no records in the log, the screen displays the message:
NO EVENTS
Viewing Additional Screens
There may be up to 99 records of event data.
• To view additional records, use the arrows ↑↓ .
• To return to the previous screen, press the ESC key.
5.3.2 Backing Up the Event Log (Service Terminal Interface only)
The event log is stored as a file in the AC8; it can hold no more than 99 records. When the log is full,
the oldest records are deleted from the end of the file as new event records are added at the beginning.
You may back up the event log file to a remote computer using the Service Terminal Interface, as
described in 6.2 - Back Up Log Files (Service Terminal Interface only).
To delete all records in the event log, see 7.13 - Clear Alarms & Logs.
