The invention concerns a pneumatic control device () for multi-zone fire extinguishing installations, comprising a control pressure inlet port () for connection to a control pressure source (), in particular a pressurised gas container, a number (m) of first control pressure outlet ports () for connection to a corresponding number of extinguishing agent containers (), a number (n) of second control pressure outlet ports () for connection to a corresponding number of zone valves (), and a plurality of function modules (). It is proposed that the invention further includes a quantity control module () for the association of a selection of the first number of control pressure outlet ports () with a selection of the second control pressure outlet ports (), and an electrical control valve module () which is controllable from the exterior for selectively opening or closing the second control pressure inlet ports () and which can be connected in particular in signal-conducting relationship to a fire alarm and/or extinguishing control station (), wherein the function modules () are operatively connected together.

Pneumatic control device for multi-zone fire extinguishing systems, and multi-zone fire-extinguishing systems having same

An extinguishing fluid nozzle system (), for stationary fire extinguishing systems, with an extinguishing fluid nozzle having a main body () which has an inlet opening () and can be fixed in fluid-conducting relationship to an extinguishing fluid line, a nozzle head () which has one or more outlet openings () connected in fluid-conducting relationship to the inlet opening for the discharge of the extinguishing fluid, and an aperture () having an aperture ring () for flow limitation, arranged in the fluid path between the inlet opening and the one or more outlet openings. The aperture has a grip portion () which is fixedly connected to the aperture ring and which extends outwardly from the aperture ring and which in the fitted condition of the aperture extends outside the extinguishing fluid nozzle.

Extinguishing-fluid-nozzle system for stationary fire-extinguishing systems

The invention relates to an inert gas fire-extinguishing system for reducing the risk of and extinguishing fires in a protected room. So as to have the inerting of the protected room ensue according to different variable sequences of events, the inert gas fire-extinguishing system includes a pressure-reducing device having at least two parallel branches, wherein each parallel branch has a pressure-reducing mechanism. Each parallel branch is connectable to a high-pressure collecting line and a low-pressure extinguishing line via a controllable valve, whereby each pressure-reducing mechanism is designed to reduce a high input pressure to a low output pressure according to a known pressure-reducing characteristic curve.
