A METHOD OF CONTROLLING ACCESS TO AN ELEVATOR CAR (5), IN PARTICULAR TO ITS CEILING (7) AND/OR UNDERSIDE, COMPRISES THE STEPS OF: SWITCHING THE ELEVATOR CONTROL INTO A MAINTENANCE MODE WHICH CONTROLS THE CAR (5) TO TRAVEL TO A PREDETERMINED STOP POSITION (W1, W4) PERMITTING ACCESS; AND OPENING A LANDING DOOR (T1, T2, T3, T4) OF THE ELEVATOR SHAFT (1) THE CAR (5) IS RUNNING IN. THE ELEVATOR CONTROL IS SWITCHED INTO SAID MAINTENANCE MODE ONLY IF OPERATING A LANDING CALL RECEIVING MEANS IN A PREDETERMINED IDENTIFICATION PATTERN WHICH DIFFERS FROM A CALL PATTERN FOR CALLING THE ELEVATOR. |
