Abstract
Ein Gefahrenmelder mit einem Gehäuse, einer innerhalb des Gehäuses ausgebildeten Messkammer (7), wobei das Gehäuse eine Einlassöffnung für die Messkammer (7) ausbildet, und einer Detektionseinrichtung zur Detektion eines in der Messkammer (7) befindlichen Gases, ist durch eine die Messkammer (7) mit der Umgebung verbindende Druckausgleichsöffnung (24) gekennzeichnet. A hazard detector having a housing, a measuring chamber (7) formed inside the housing, wherein the housing forms an inlet opening for the measuring chamber (7), and a detection device for detecting a gas located in the measuring chamber (7), are separated by a measuring chamber (FIG. 7) communicating with the environment pressure equalization port (24).
