## Discrepancy

WHILE DESCENDING THROUGH APPROXIMATELY FL200, THE BAGGAGE SMOKE ANNUNCIATOR AND MASTER WARNING SWITCH LIGHT ILLUMINATED. WE DECLARED AN EMERGENCY AND BEGAN A DIVERSION TO THE CLOSEST AIRPORT WITH ARFF. WE CONSULTED THE CHECKLIST AND THE ONLY STEP WAS LAND AS SOON AS POSSIBLE. WE MADE AN UNEVENTFUL LANDING AT FLL, EVACUATED THE AIRCRAFT ON THE TAXIWAY, AND HAD IT INSPECTED BY ARFF. NO SMOKE OR FIRE WAS DETECTED IN EITHER BAGGAGE COMPARTMENT. WE THEN TAXIED UNDER OUR OWN POWER TO SIGNATURE.
