Feuermeldevorrichtung.
Gegenstand vorliegender Erfindung ist eine Feuermeldovorrichtung, welche auf einer Feuerwohrwache oder dgl. einen Brand anzeigen soll, der an seinem Entstohungsort einen Spannungsabfall in einer Druckleitung hervorruft und hiebei auch noch eine selbsttätige Löschung bewirken kann. Der Erfindung liegt das bekannte Prinzip zugrunde, dass mittels
EMI1.1
getragen wird, der bei Veränderung des Flüssigkoitsspiegels eine Verschiebung erfährt und hiebei abwechselnd einen Stromschluss und eine Stromunterbrechung herbeiführt.
Die Vorrichtung ist auf der Zeichnung in zwei Längsschnitten dargestellt, von denen derjenige in Fig. 1 die Vorrichtung in der Ruhestellung wiedergibt, während Fig. 2 die-

Im allgemeinen bewirkt der Druck der Luft oder der Flüssigkeit, von welchem die Feuerlöschvorrichtung abhängig gemacht wird, ein Ansteigen der Flüssigkeit in den Gefässen A, Bund C derart, dass der Schwimmer D in die in Fig. 1 gezeichnete Ilüchstlago kommt. Fällt bei Ausbruch eines Brandes infolge der dabei auftretenden Temperatur-

Fire alarm device.
The subject of the present invention is a fire alarm device which is intended to indicate a fire to a fire station or the like, which causes a voltage drop in a pressure line at its source and can also cause automatic extinguishing. The invention is based on the known principle that by means of
EMI1.1
is carried, which experiences a shift when the level of the liquid carbonate changes and alternately causes a current connection and a current interruption.
The device is shown in the drawing in two longitudinal sections, of which the one in Fig. 1 shows the device in the rest position, while Fig. 2 shows the
EMI1.2
In general, the pressure of the air or the liquid, on which the fire extinguishing device is made dependent, causes the liquid in the vessels A, B and C to rise in such a way that the float D comes into the Ilüchstlag shown in FIG. If a fire breaks out due to the resulting temperature
EMI1.3
In addition, a Morse telegraph or the like can be excited at the fire station, which is connected to the present device, which makes lines of the length corresponding to the bund height on an unrolling strip of paper, while the
