Abstract

The invention relates to a process and a device for sending a call signal of call button circuit in a lift, which signal has been generated by a frequency change. In the process, the frequency of the call button circuit is compared with a comparison value and a lift call signal is sent on the basis of this comparison. According to the invention, the frequency of the call button circuit at successive points in time is compared with the comparison value which applies at the point in time in question and the comparison value is changed for a value which has been generated by the frequency of at least one call button circuit at an earlier point in time. The device according to the invention comprises at least one unit 3 for comparing the frequency of the call button circuit with a comparison value which applies at the point in time, and at least one unit 2 for generating a new comparison value on the basis of at least one frequency applying at an earlier point in time. <IMAGE>
