## Discrepancy

DEPARTING KSRQ 9/18/25, THE CREW NOTICED THE CABIN FIRE WARNING LIGHT ILLUMINATED. THE SYSTEM SENSOR IS IN THE CABIN AREA BAGGAGE COMPARTMENT. THE CAPTAIN INSTRUCTED THE FO TO GO BACK AND VISUALLY INSPECT THE BAGGAGE COMPARTMENT. NO SMOKE WAS NOTICED. THE CAPTAIN REPORTED THAT THE LIGHT WOULD COME ON AND GO OUT WITH POWER LEVER ADJUSTMENTS SO HE ELECTED TO DIVERT INTO KOPF. THE LIGHT WENT OUT AND STAYED OUT DESCENDING INTO OPF.  AND THERE WAS STILL NO SMOKE SMELL. THE AIRCRAFT WAS LANDED SAFELY IN OPF. LOCAL MAINTENANCE INSPECTED THE BAGGAGE SMOKE DETECTOR SYSTEM AND FOUND THAT WHEN THE SENSOR WAS MOVED, THE LIGHT WOULD FLICKER. A NEW SMOKE DETECTOR/SENSOR WAS ORDERED AND INSTALLED. THE ISSUE COULD NOT BE DUPLICATED AS BEFORE AND THE SMOKE DETECTION SYSTEM TESTED NORMALLY. THE AIRCRAFT HAS COMPLETED TWO FLIGHTS SINCE THE DIVERSION WITH NO ISSUES REPORTED.
