Reading the Alarm Log from a Terminal or Computer
To display the Alarm Log on a terminal or computer, you can use the
alarmlog or logs command (see “Entering Commands from a Terminal
or Computer” page 44). These commands display up to 20 log entries in
a table. For example, the log might look like this table:
Active EventDate EventTime Duration Code/Event
No 08/25/1993 11:25:32 00:00:45 J-User Test Alarm
No 08/24/1993 12:13:18 00:01:08 A-Low Battery
No 08/24/1993 12:05:07 00:08:11 B-Near Low Battery
The table shows whether the alarm is active now (Active), the date and
time of each alarm, how long it lasted (Duration), and what caused the
alarm (Code/Event).
You can also display parameter 25 to view the Alarm Log; this display is
the same as the control panel display.
