The number of alarms displayed

The number of objects displayed on the Control Panel is determined by the current filter if it is activated by clicking the filtering button  ("Enable/disable filter").

The upper-left corner contains information about the number of objects, out of the total number, that are displayed on the Control Panel after clicking the filtering button.
