It relates to a security device for a building according to the preamble of claim 1.

Stand der TechnikState of the art

Explosionen in Gebäuden, welche durch defekte Gasleitungen verursacht werden, haben oft verheerende Folgen. Vor allem im Brandfall ist ausströmendes Gas unberechenbar. Selbst wenn Gasmeter strenge Sicherheitsvorschriften erfüllen und im Falle einer erhöhten Umgebungstemperatur oder eines Gaslecks die Gaszufuhr unterbrechen würden, wäre das Risiko nicht gebannt. Da sich diese Gasmeter üblicherweise in einem Untergeschoss des Gebäudes befinden, ist es, wenn in diesem Raum eine Störung festgestellt wird, oft schon zu spät. Der Brand kann in einem oberen Stockwerk ausgebrochen sein, und es ist durchaus möglich, dass das einzige, was zu diesem Zeitpunkt noch vom Gebäude übrig ist, das Untergeschoss mit dem Gasmeter ist. Explosions in buildings caused by defective gas pipes are often devastating. Especially in In the event of fire, escaping gas is unpredictable. Even if gas meter meet strict safety regulations and in the event of a increased ambient temperature or a gas leak would interrupt if the risk had not been averted. That I these gas meters are usually in a basement of the building it is when a disturbance is found in this room is often too late. The fire can be on an upper floor have broken out, and it is quite possible that that only thing that is left of the building at that time, that Basement with the gas meter is.
