    Abstract: The present invention is concerned with an alarm system and a method for suppressing redundant alarms in a monitored system. The alarm system comprises a process control unit, an FDI unit, a filter, and an alarm display unit. The process control unit detects anomalies in the monitored system and generates alarms corresponding to them. The FDI unit diagnoses failures in the monitored system and generates a failure-cause-effect graph comprising a list of generated alarms, along with the alarms corresponding to the causes and effects of each listed alarm. The FDI unit dynamically updates the failure-cause-effect graph concurrently with the generation of alarms by the process control unit and the diagnosis of failures by the FDI unit. The filter receives the generated alarms and identifies redundant and not-yet-classified alarms from the received alarms, by using the failure-cause-effect graph. The filter suppresses the identified redundant alarms and passes on non-redundant and the not-yet-classified alarms to the alarm display unit, for display.
