Abstract (en)
The unit has a signal buzzer (2) for producing an acoustic signal, and a housing (1) for inputting an acknowledgement of the signal by an operating person. A sensor unit detects the acknowledgement and a parameter e.g. amplitude and frequency of the signal. The sensor unit has a control unit for normal and actual value comparison of the parameter such that the acknowledgement produces an actual value.
