EN ROUTE TO PIT, A SMOKE DETECT FAIL WARNING MESSAGE ILLUMINATED.  A PASSENGER WAS EXITING THE RESTROOM, AND THE FLIGHT ATTENDANT NOTICED THAT THE SMOKE DETECTOR HAD BEEN TAMPERED WITH.  THE AIRCRAFT CONTINUED ON TO PIT AND LANDED.  THE PASSENGER WAS DETAINED BY AIRPORT SECURITY.  MAINTENANCE CONFIRMED THE TAMPERED CONDITION OF THE SMOKE DETECTOR, AND REPLACED IT, IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 26-15-01.  OPERATIONAL CHECKS WERE COMPLETED, AND THE AIRCRAFT WAS RETURNED TO SERVICE.
