ABSTRACT:
A system for detecting data such as telecommunication calls, alarm calls, fire calls in which the rapidity of the locating of data is obtained by a simultaneous detection at several levels is disclosed. It comprises a meshed network having several levels, a counter which locates the data at that level being related to each level, the counters progressing successively under the control of a supervising element and being blocked each in turn by that element when a data item is detected at the corresponding level. The invention is applicable, to great advantage, in telecommunications and alarm systems.
