## Discrepancy

PDX - AFTER TAKE-OFF, THE LAVATORY SMOKE DETECTOR WENT OFF.  THE FLIGHT ATTENDANT VERIFIED THAT IT WAS ON, BUT NO FIRE OR SMOKE WAS NOTICED.  THE DETECTOR SILENCED AFTER APPROXIMATELY 2 MINUTES.  THE UNIT TESTED OK.  MAINTENANCE INSPECTED THE DETECTOR AND IT TESTED GOOD IAW-8 (400) 26-12-11, TASK 26-12-11-710-801.  THE AIRCRAFT WAS RETURNED TO SERVICE.  NO PARTS WERE REPLACED.
