ABSTRACT:
A danger warning system includes a central station and modules connected via at least one series connection. A mechanism in the central stations determines the distance between the central station and the modules. The modules are triggered by the central station, such that an energy store is charged in the central station, and the mechanism for determining the distance evaluates the charging time of the energy store.
