## Discrepancy

WHILE AIRCRAFT 806EX WAS IN MANCHESTER NEW HAMPSHIRE CREW NOTED THAT THE LAVATORY SMOKE ALARM WAS ACTIVATED AND WOULD NOT EXTINGUISH.  CREW THEN COMPLIED WITH MEL BY PULLING C/B AND PLACARD LAV AS REQUIRED.  LATER LAQUARDIA MAINTENANCE REMOVED AND REPLACED LAVATORY SMOKE ALARM AND OPERATIONAL CHECK WAS GOOD.
