It depends on why it went INVALID

Several possible things.  It surprises me that the record dump below  
shows the .STAT field as NO_ALARM.  Usually the .STAT field gives an  
indication of why the record went into alarm ... someone is not  
following the rules.

Did you print this record immediately after it went into alarm?
