NOTE

TE::::: The alarm management system is designed to provide self-update

behavior, thereby no user intervention is required to restore the status of the
interrupted program once the condition is resolved. If the condition of the
active alarms change, the panel will reflect the change accordingly without
user intervention. However certain alarms might cause the controller to enter
the STOP state. In this state the controller stops all activities and waits for the
user intervention.
