## Discrepancy

TWO HOURS INTO FLIGHT, HAD A QUICK FLASH ALERT LEVEL 2 FOR  THE NR 2 ENGINE FIRE LOOP A, LASTED ONE SECOND AND WENT AWAY.  15 MINUTES LATER HAD STEADY LEVEL 2 ALERT FOR  LOOP B.  RAN QRH CHECKLIST, LOOP A TESTED GOOD.  OPERATED IN LOOP A AT THAT POINT.  ALL OTHER ENGINE  INDICATIONS LOOKED NORMAL.  NOT USING NR 2 PACK SO CLOSED THE NR 2 ENGINE BLEED AIR SWITCH AS A PRECAUTION. 10  MINUTES LATER RECEIVED A NR 2 ENGINE FIRE WARNING.  RAN THE ENGINE FIRE CHECKLIST, SHUT DOWN THE NR 2 ENGINE, USED BOTH FIRE BOTTLES,  FIRE WARNING REMAINED ON DIVERTED.  R2D 9TH STAGE COOLING DUCT IAW AMM 70-00-00-2.
