Abstract

Das Gasexplosionsschutzgerät enthält einen Gassensor (GS), der die An- oder Abwesenheit von brennbaren Gasen feststellt und einen Signalzustand "Gefahr" betreffend der Anwesenheit solcher brennbarer Gase einnimmt. Daraufhin gibt ein Encoder (EC) mit zugeordnetem Sender ein codiertes Alarmsignal an die Hausnetzleitung (NL) weiter, an welcher das Gerät angeschlossen ist. Ein Decoder (DC) mit zugeordnetem Empfänger ist an entfernter Stelle an die Hausnetzleitung (NL) angeschlossen ist, spricht auf das codierte Alarmsignal an und veranlaßt die Abgabe eines Stellsignals. Eine Schalteinrichtung (SR) wird von dem Decoder aktiviert und schaltet die Hausnetzleitung (NL) im Gefahrenbereich ab.

Figure 00000001
The gas explosion protection device contains a gas sensor (GS), which detects the presence or absence of flammable gases and assumes a "danger" signal state regarding the presence of such flammable gases. An encoder (EC) with an assigned transmitter then sends a coded alarm signal to the house network line (NL) to which the device is connected. A decoder (DC) with an assigned receiver is connected to the home network line (NL) at a remote location, responds to the coded alarm signal and causes an actuating signal to be emitted. A switching device (SR) is activated by the decoder and switches off the house network line (NL) in the danger zone.
