2.1 Behaviour when an Alarm comes up
Whenever an alarm is raised, the processing is a two-step action:
1. Switch off the acoustic alarm, if there is one. Use the Stop Horn button in the GUI
or press the button on the keyboard, if it is available.
Some alarms do not trigger the acoustic alarm. This depends on the settings made in the configu-
ration database of the Integration Manager.
Some alarms can only be switched off at the MFD that has originated the alarm. For example, a
Trackpilot alarm can only be acknowledged at the MFD that is set as Trackpilot Master.
2. Immediately obtain information about the causes of the alarm or warning, about the system state
and about possible system reactions, and - if necessary - immediately perform all necessary actions
for the avoidance of possible danger.
3. Remove the cause of the alarm or warning: If an alarm has occurred due to a cause that can be
removed, that cause must be removed as quickly as possible; see also section V - 2.2: "List of
Alarms". Alarms with priority 4 disappear when the cause disappears. Acknowledgement is then
unnecessary. Alarms with priority 1, 2 and 3 must be acknowledged in any case.
4. The alarms with priority 1 and many alarms of priority 2 and 3 must be acknowledged if the situa-
tion allows or requires such acknowledgement. There are two possibilities to acknowledge alarms:
- Click on Acknowledge in the alarm line
- Click on Acknowledge All in the heading of the Alarm list
If alarms or warnings are also distributed to other items of equipment within the system, or if the system
deviates from the behaviour described above, e.g.
- if the alarm cannot be acknowledged at all or throughout the entire system, or
- if acknowledgement causes something to be initiated or enabled, or
- if an acknowledged alarm is repeated for as long as the cause of the alarm continues to exist.
These situations are mentioned in section V - 2.2: "List of Alarms".
Removing acknowledged alarms from the list is done automatically by the system, in case the alarm
reason is no longer valid, or the application or operating mode has been switched off.
