Narrative:

Engine fire warning and shutdown. During cruise flight, the #2 engine fire warning light, the fire warning bell, and the master fire warning light began to flicker. At first it was slow, but they began to flicker more often and stay on longer. Nearing the top of descent, the fire bell came on steady and would not silence unless held since the warnings were still intermittent. After bringing the power back for descent, all warnings became steady. We were able to silence the bell and we ran the engine fire checklist. After firing both bottles, the engine fire warning light remained illuminated so I notified ATC that we were declaring an emergency due to engine failure. Preparing for landing we: informed the flight attendants, contacted both operations and dispatch, accomplished the 1-ENG inoperative approach and final descent checklists, figured performance data for a flaps 15 degree landing, requested emergency equipment to stand by, and made a PA advising the passenger of our situation and tried to assure them of a normal and safe landing. The single engine approach and landing were uneventful and the fire warning light extinguished after landing. So we taxied to our gate without further assistance.

AT FIRST IT WAS SLOW, BUT THEY BEGAN TO FLICKER MORE OFTEN AND STAY ON LONGER.

PREPARING FOR LNDG WE: INFORMED THE FLT ATTENDANTS, CONTACTED BOTH OPS AND DISPATCH, ACCOMPLISHED THE 1-ENG INOP APCH AND FINAL DSCNT CHKLISTS, FIGURED PERFORMANCE DATA FOR A FLAPS 15 DEG LNDG, REQUESTED EMER EQUIP TO STAND BY, AND MADE A PA ADVISING THE PAX OF OUR SIT AND TRIED TO ASSURE THEM OF A NORMAL AND SAFE LNDG.
