THE INVENTION RELATES TO A SAFETY SYSTEM FOR A LIFT INSTALLATION (10) FOR THE TRANSPORT OF PERSONS/GOODS IN BUILDING (30) AND TO A METHOD FOR OPERATING A LIFT INSTALLATION (10) WITH A SAFETY SYSTEM. SEVERAL CAGES (2, 2'') ARE MOVER ONE ABOVE THE OTHER IN A SHAFT (31). EACH CAGE (2, 2'') IS MOVE BY A DRIVE (6, 6''). AT LEAST ONE DRIVE CONTROL (16, 16'') CONTROLS THE DRIVES (6, 6'') BY WAY OF DRIVE CONTROL SIGNALS. CAGE POSITION DETECTING SENSORS (21, 21'') DETECT POSITIONS OF EACH CAGE (2, 2'') AND TRANSMIT CAGE POSITION DATA AT LEAST ONE SAFETY CONROL (26, 26''). ACCESS TO THE SHAFT (31) TAKES PLACE BY WAY OF OPENED SHAFT DOORS (11.0 TO 11.8). A LOCK (18.0 TO 18.8) LOCKS SHAFT DOORS (11.0 TO 11.8). LOCK SETTING DETECTING SENSORS (20.0 TO 20.8) DETECT SETTING OF THE LOCKS (18.0 TO 18.8) OF THE SHAFT DOORS (11.0 TO 11.8) AND TRANSMIT LOCK SETTING DATA BY WAY OF THE DATA BUS (22) TO THE SAFETY CONTROL (26, 26''). THE SAFETY CONTROL (26, 26'') ASCERTAINS, FROM THE CAGE POSITION DATA AND THE LOCK SETTING DATA, SHAFT REGION DATA WITH DETAILS WITH RESPECT TO SHAFT REGIONS IN WHICH EACH CAGE (2, 2'') IS SAFELY MOVEABLE. THE SAFETY CONTROL (26, 26'') TRANSMITS THE SHAFT REGION DATA TO THE DRIVE CONTOL (16, 16''), WHICH CONVERTS THE SHAFT REGION DATA INTO DRIVE CONTROLS SIGNALS IN ORDER TO MOVE THE CHANGES (2, 2'') IN SEPARATE SHAFT REGIONS AND IN ORDER TO MOVE THE CAGES (2, 2'') IN SHAFT REGIONS WITH LOCKED SHAFT DOORS (20.0 TO 20.8).(FIG. 1)
