Abstract

In Hybridsystemen mit Funkmeldern und leitungsgebundenen Meldern wird ein sichererer Betrieb dadurch erreicht, daß die Spannung auf der Meldeleitung (2) während des Betriebs bestimmt wird. Sinkt die Spannung auf der Meldeleitung (2) unter einen vorgegebenen Wert ab, so wird die Kommunikation zwischen den Funkeinheiten (G1...Gn) und den Funkmeldern (3) derartig beeinflußt, daß weniger Energie aufgenommen wird.
