Liftsafe 2 switches off the elevator in the event of safety-related errors and reports the cause. Liftsafe also reports broken cabin lighting or if the elevator does not stop flush. Test messages can be triggered for test purposes. Detected deviations from normal operating status are saved in the emergency call center with the date, time and type of error. The status of all important modules is indicated by LEDs. A “test” message can be send without influencing the elevator. Liftsafe 2 consists of 3 modules.
Thanks to the modular system, you can conveniently monitor the status of the device in real time from the control box. 1.
