This reports the current state of whatever station object triggered the alarm entry, as one of normal(0), offnormal(1), fault(2), or alert(3). An admin watches this value to see whether the underlying point has recovered or is still faulted, independent of whether anyone has acknowledged the alarm itself. For example, a sourceState of fault(2) on a temperature sensor's alarm row indicates the sensor hardware is still reporting a fault even if the alarm has already been acked.
