Claims (7)

1. Gasexplosionsschutzgerät mit folgenden Merkmalen:
ein Gassensor (GS), der die An- oder Abwesenheit von brennbaren Gasen feststellt und einen Signalzustand "Gefahr" betreffend der Anwesenheit solcher brennbarer Gase einnimmt;
ein Encoder (EC) mit zugeordnetem Sender, der entsprechend dem Signalzustand "Gefahr" des Gassensors ein codiertes Alarmsignal an die Hausnetzleitung (NL) weitergibt, an welcher das Gerät angeschlossen ist;
ein Decoder (DC) mit zugeordnetem Empfänger, der an entfernter Stelle an die Hausnetzleitung (NL) angeschlossen ist, auf das codierte Alarmsignal anspricht und die Abgabe eines Stellsignals veranlaßt;
eine Schalteinrichtung (SR), die von dem Decoder aktivierbar ist und die Hausnetzleitung (NL) im Gefahrenbereich abschaltet.1. Gas explosion protection device with the following features:
a gas sensor (GS) which detects the presence or absence of combustible gases and assumes a "danger" signal state relating to the presence of such combustible gases;
an encoder (EC) with an associated transmitter, which forwards a coded alarm signal to the domestic power line (NL) to which the device is connected in accordance with the "danger" signal state of the gas sensor;
a decoder (DC) with an assigned receiver, which is connected at a remote location to the house network line (NL), responds to the coded alarm signal and causes an actuating signal to be emitted;
a switching device (SR) that can be activated by the decoder and switches off the house network line (NL) in the danger zone. 2. Gasexplosionsschutzgerät nach anspruch 1, dadurch gekennzeichnet, daß eine Warneinrichtung von dem Stellsignal ansteuerbar ist.2. Gas explosion protection device according to claim 1, thereby characterized in that a warning device from the Control signal is controllable. 3. Gasexplosionsschutzgerät nach Anspruch 1 oder 2, dadurch gekennzeichnet, daß eine automatische Telefonwählein­ richtung (TWE) beim Ansprechen des Decoders ansteuerbar ist. 3. Gas explosion protection device according to claim 1 or 2, characterized characterized by an automatic telephone dialing direction (TWE) can be controlled when the decoder is activated is.   4. Gasexplosionsschutzgerät nach einem der Ansprüche 1 bis 4, dadurch gekennzeichnet, daß ein Ventilstellantrieb (VSA) von dem Stellsignal antreibbar ist, der ein Sperrventil in der Gaszuführleitung des Gebäudes aufweist, in welchem das Gerät installiert ist.4. Gas explosion protection device according to one of claims 1 to 4, characterized in that a valve actuator (VSA) can be driven by the control signal, the one Stop valve in the gas supply line of the building in which the device is installed. 5. Gasexplosionsschutzgerät nach einem der Ansprüche 1 bis 4, dadurch gekennzeichnet, daß dem Decoder (DC) ein Speicher (SR) zugeordnet ist, der den Alarmzustand solange aufrechterhält, bis dieser willentlich aufgehoben wird.5. Gas explosion protection device according to one of claims 1 to 4, characterized in that the decoder (DC) Memory (SR) is associated with the alarm condition maintained until it deliberately will be annulled. 6. Gasexplosionsschutzgerät nach einem der Ansprüche 1 bis 5, dadurch gekennzeichnet, daß ein Gaswarnzusatzgerät (GWZ) an eine beliebige Haussteckdose der Hausnetzlei­ tung (NL) anschließbar ist und einen Demodulator sowie eine von diesem gesteuerte Alarmsirene enthält.6. Gas explosion protection device according to one of claims 1 to 5, characterized in that a gas warning device (GWZ) to any house socket of the house network device (NL) can be connected and a demodulator as well contains an alarm siren controlled by it. 7. Gasexplosionsschutzgerät nach einem der Ansprüche 1 bis 6, dadurch gekennzeichnet, daß eine automatische Telefonwähleinrichtung (TWE) an eine beliebige Haus­ steckdose der Hausnetzleitung (NL) anschließbar ist und einen Demodulator als Empfänger sowie einen Decoder enthält.7. Gas explosion protection device according to one of claims 1 to 6, characterized in that an automatic Telephone dialing device (TWE) to any house socket of the house power line (NL) can be connected and a demodulator as a receiver and a decoder contains.
