Abstract

Ein Gefahrenmelder mit einer Messkammer, einer eine Detektionseinrichtung zur Detektion eines in der Messkammer befindlichen Gases umfassenden Funktionseinheit, einer Spannungsquelle und einer elektrische Schaltung, durch die die Funktionseinheit mit der Spannungsquelle elektrisch verbindbar ist, ist dadurch gekennzeichnet, dass die Schaltung einen Transistor umfasst, der in einer Deaktivierungsschaltstellung die Funktionseinheit von der Spannungsquelle trennt und in einer Aktivierungsschaltstellung die Funktionseinheit mit der Spannungsquelle verbindet.

Figure imgaf001
A hazard detector comprising a measuring chamber, a functional unit comprising a detection device for detecting a gas in the measuring chamber, a voltage source and an electrical circuit by means of which the functional unit can be electrically connected to the voltage source is characterized in that the circuit comprises a transistor which in a deactivation switching position, the functional unit separates from the voltage source and connects the functional unit to the voltage source in an activation switching position.
