## Discrepancy

INDICATION OF LAVATORY SMOKE. INDICATION ONLY LASTED FOR A FEW SECONDS AND THEN EXTINGUISHED.  LAVATORY WAS CHECKED AND NO INDICATION OF A FIRE WAS PRESENT.  SMOKE WARNING CAME ON A SECOND TIME AND WENT OFF.  CIRCUIT BREAKERS PULLED IAW THE CHECKLIST AND RECIRCULATION FAN WAS TURNED OFF.  RETURNED TO PQI.
