ACTIVE EVENTS and event management
If you select ACTIVE EVENTS and press ENT, a list will show the current active events.
If Alarms and Faults/Emergency are present at the same time, these will be shown on
two screens.
Fig. 3-8) Active Events screens
In case of a new event, the screen will automatically switch to the ACTIVE EVENTS
screen and the unit's internal buzzer will sound. Until ACK is performed for the new
event, it will not be possible to return to the main screen.
The screens in Figure 3.5.1 show events for which ACK has not yet been performed.
Once the event has been acknowledged (ACK performed), an "X" is shown in the right
column.
In case of Active Events, it is possible to perform 3 operations:
-Press ENT for more details on the event
Press ACK to acknowledge the event and silence the central unit buzzer.
