The historical deletions can be used to remove historical faults, historical linkage, historical fire
alarms and historical operations, and this historical information can be deleted by selecting relevant
option.
Barring special circumstances, the user is not suggested to
delete historical records. As important materials required for system maintenance,
the historical records are kept circularly and the latest 1000 records will be saved;
therefore, issues such as excessing storage capacity and failing to record will not
occur.
