Abstract: The invention concerns a pneumatic control device (1) for multi-zone fire extinguishing installations, comprising a control pressure inlet port (25) for connection to a control pressure source (105), in particular a pressurised gas container, a number (m) of first control pressure outlet ports (17) for connection to a corresponding number of extinguishing agent containers (107), a number (n) of second control pressure outlet ports (19) for connection to a corresponding number of zone valves (111), and a plurality of function modules (7, 9).

Abstract: The invention relates to a multi-area fire extinguishing system, having a control system, a number of fluid control lines that are configured to transmit a control pressure as a function of control commands of the control system, and a number of fluid-actuated area valves that are each in fluid communication with the control lines, wherein the area valves are configured to be actuated as a function of the received control commands. The invention proposes, in particular, a fluid-actuated area blocking apparatus which is operatively coupled to the fluid control lines and to the area valves and which is configured such that, when one or more area valves are actuated, said area blocking apparatus opens up those area valves and blocks all other area valves. The invention furthermore relates to a controller for a multi-area fire extinguishing system, to an area blocking apparatus for a fire extinguishing system, and to the use of same.

Abstract: A method is disclosed for moisture tight covering a connection point between an electrical conductor. The method includes exposing the conductor at its end by removing the insulation and subsequently electrically conductively connecting the end of the conductor, from which the insulation has been removed, to the contact element. After the connection point is finished, a foil of insulation material is positioned underneath the connection point, where the foil rests against the insulation of the conductor and at least partially against the contact element. Subsequently, a sealing material capable of hardening is applied from above onto the conductor, wherein the sealing material is flowable during its application and subsequently changes over by hardening into a mechanically stable state which extends beyond the insulation of the conductor and beyond the contact element and is connected tightly to the foil.

Abstract: A method for sealing an electric coupling piece (K) against moisture, includes, at an end of the line (1) intended for connection to the coupling piece (K), at least one annular groove extending in the circumferential direction is cut into the casing of the line (1). Prior to injection molding the protective body (9), an O-ring (10) serving as a sealing element is placed into the groove, where the O-ring (10) rests tightly against the lateral borders of the groove (11) with the respective pretension, where the O-ring is of a material which connects tightly and in a moisture proof manner to the insulating material of the finely produced protective body (9).

Abstract: A method of making cable includes injection molding a coupling part which is manufactured from a polymer mixture with a thermoplastic material as polymer component, where the cable casing contains thermoplastic polyurethane cross-linked by radiation. The cable has a water-tight and fixed connection between the casing of the cable and the section of the coupling part injection molded around the casing.
