The elevator attendant device is used for remote monitoring and operational control of elevators. The elevator attendant device sends messages to the emergency call device. The emergency telephone then communicates via the public telephone network or sends SMS messages about the operating status of the elevator to the service center. In the event of safety-related errors, Liftsafe can switch off the elevator at the stop and report the cause. In addition, the Liftsafe reports defective cabin lighting and if the lift does not stop flush. For test purposes, test messages (by error simulation or technician present switch) can be triggered.
