## Discrepancy

THE THREE LAVATORY SMOKE DETECTOR ALARMS WERE FLASHING AND DID NOT TURN OFF.  THE SYSTEM WAS RESET BUT THE ALARM CONTINUED RINGING.  DUE TO SUCH A FAILURE, A CHANGE OF EQUIPMENT WAS REQUESTED.   THE  SYSTEM AND THE SMOKE DETECTOR CONNECTORS WERE CHECKED, AUTO TEST WAS PERFORMED AND IT WAS OK.
