## Discrepancy

CREW HAD A NR1 ENG FIRE WARNING LIGHT ON DURING TRAINING FLIGHT WITHOUT ACTUAL FIRE. CAME BACK TO THE AIRPORT.  TROUBLESHOOTING REVEALED THAT FIRE DETECTOR LOCATED ABOVE COMBUSTION CHAMBER AREA WAS SENDING A CONTINUOUS FIRE ALARM SIGNAL TO THE SYS EVEN WITHOUT AN ACTUAL FIRE. PART REPLACED AND SYS TESTED SERVICEABLE. ACFT RETURNED TO SERVICE.
