format.
The alarm name, delay time, delay enabling and alarm type are displayed from left to right in the list.
The alarm delay can be set to 0 ~ 9999. Unit: second.

'Yes' and 'No'.
The alarm type can be set to 'ALM' (alarm), 'WRN' (warning) and 'MSG' (message). They determine the alarm degree
of the corresponding event.
