Weise bewirken. An Stelle der von Hand zu betätigenden Schalter 16 können selbsttätige Schalter, wie z. B. Thermostate, benutzt werden. In den Fällen, wo das System gemäss der Erfindung bei Feueralarm-oder Einbruchssystemen oder ähnlichen Alarmvorrichtungen Verwendung finden soll, werden die Drähte 4 und 5 durch die zu schützenden Räume gezogen, so dass von irgend einem der Räume aus die Signale übermittelt werden.

Mit Ruhestrom betriebene Signalvorrichtung mit sowohl in der Zentrale als auch in der Unterstation geerdeter Doppelleitung, dadurch gekennzeichnet, dass bei einer durch Leitungbruch, Kurzschluss oder Erdschluss verusachten Störung in dem mit dem geerdeten Pol der Stromquelle verbundenen Zweige der Doppelleitung der andere Zweig, der im normalen Zustande der Leitung an den geerdeten Pol angeschlossen ist, selbsttätig an den nichtgeerdeten Pol geschaltet wird, wodurch der intakt geblieben Zweig beiderseits geerdet ist.

Effect wise. Instead of the manually operated switch 16, automatic switches such. B. thermostats can be used. In cases where the system according to the invention is to be used in fire alarm or intrusion systems or similar alarm devices, the wires 4 and 5 are pulled through the rooms to be protected so that the signals are transmitted from any of the rooms.
EMI4.1
1.
Signaling device operated with quiescent current with a double line grounded both in the control center and in the substation, characterized in that in the event of a fault caused by a line break, short circuit or ground fault in the branch of the double line connected to the earthed pole of the power source, the other branch, which is normally used State of the line is connected to the grounded pole, is automatically switched to the non-grounded pole, whereby the branch that has remained intact is grounded on both sides.
