## Discrepancy

AT FL320 CARGO FIRE, LOWER AFT DISPAYED WITH MASTER WARNING, LEVEL 3 ALERT AND   AURAL TONE.  DISCHARGED BOTH BOTTLES DURING REMAINDER OF FLIGHT.

BOTH FIRE BOTTLES WERE DISCHARGED AND AGENT LOW LIGHTS ILLUMINATED.  AS A PRECAUTION, NEED TO INOP   SMOKE DETECTORS IN AFT AND BULK COMPARTMENTS,  HENCE ALL 5 SMOKE DETECTOR   UNITS DISCONNECTED.  ACFT OK FOR SERVICE.
