Claims (1)

Patent-Anspruch:Patent claim: Elektrische Alarmleitung, dadurch ge kennzeichnet, daß ein oder mehrere geradegerichtete, straff oder klingend straff gespannte blanke Leiter einem oder mehreren ebenfalls geradegerichteten bzw. ebenfalls straff bzw. klingend straff gespannten Leitern dergestalt genähert sind, daß die getrennt zueinander angeordneten Leiter beim Durchschneiden, Zerreißen o. dgl. durch die hierdurch entstehende Entspannung und Krümmung des Leiters gegeneinander treffen und durch ihre leitende Berührung in an sich bekannter Weise den Alarmstromkreis schließen.Electrical alarm line, characterized in that one or more straightened, taut or sounding taut bare conductors one or more likewise straightened or likewise taut or sounding taut ladders are approximated in such a way that the separated mutually arranged conductors when cutting through, tearing or the like. Due to the resulting relaxation and Curvature of the conductor meet against each other and through their conductive contact in a known manner the alarm circuit conclude.
