## Discrepancy

HOLDING SOUTH OF 92LA AT 500' AGL FOR COMPANY TO CLEAR HOSPITAL HELIPAD, #2 ENGINE FIRE WARNING TONE SOUNDED, #2 ENGINE FIRE LIGHT ILLUMINATED, MASTER CAUTION LIGHT ILLUMINATED, AND #2 FIRE T-HANDLE LIGHT ILLUMINATED.  AFTER ASSESSING THE SITUATION, CREW DECIDED TO SHUT DOWN #2 ENGINE.  #2 ENG. T-HANDLE WAS IDENTIFIED AND PULLED FULL AFT AND #2 ENGINE CONFIRMED TO BE SHUTTING DOWN. WE PAUSED OUR ACTIONS HERE TO OBSERVE THE TRANSITION TO OEI FLIGHT AND LIGHTS & TONE STOPPED FOR A BRIEF PERIOD AFTER #2 ENG. WAS SHUT DOWN. LIGHTS & TONE THEN RETURNED, AND A DECISION WAS MADE TO DEPLOY THE MAIN FIRE EXTINGUISHER. WE THEN PAUSED TO EVALUATE THE RESULT OF THE MAIN FIRE EXTINGUISHER ACTIVATION AND LIGHTS & TONE WERE STOPPED FOR A BRIEF PERIOD.  LIGHTS & TONE RETURNED AGAIN, AND A DECISION WAS MADE TO DEPLOY THE RESERVE FIRE EXTINGUISHER. WE THEN PAUSED TO ASSESS THE SITUATION AND LIGHTS & TONE AGAIN STOPPED FOR A BRIEF PERIOD BUT THEN RESUMED PRIOR TO LANDING. IN ALL INSTANCES, TONES & LIGHTS WERE CONTINUOUS AND NOT FLICKERING. AFTER LANDING IT WAS DETERMINED THAT THERE WERE NO SIGNS OF FIRE, AND IT WAS A WARNING SYSTEM MALFUNCTION ONLY. MAINTENANCE INVESTIGATION OF CAUSE OF WARNING MALFUNCTION IS ONGOING. POST FIRE SUPPRESSION SYSTEM ACTIVATION MAINTENANCE IAW EMM & AMM IS IN PROGRESS.
