Installed fire extinguishing apparatus, especially for the fire protection of use locations comprising endangered structures separated from each other by spaces

The invention relates to an installed fire extinguishing apparatus, which has a pressure- resistant storage body (10) with an internal space (11) for accommodating the fire extinguishing material composition (1) transportable in a pipeline, at least one dispersion device (3), and at least one transport pipeline (20) which is suitable for transporting the fire extinguishing material composition (1) from the internal space (11) of the storage body (10) to the dispersion device (3) arranged at the use location (2), where the storage body (10) is formed by a long pipeline (C) or a pipeline (C) that returns on itself that has a straight line main axis (T) or a main axis (T) of another shape, a trigger part-unit (4) is installed in the transport pipeline (20), and the storage body (10) is connected to a filling fitting (6) serving for filling the fire extinguishing material composition (1) or the components of the fire extinguishing material composition (1) into the internal space (11) of the storage body (10), the storage body (10) is coupled with at least one gas vessel (30), the internal space (31) of the gas vessel (30) is connected to the internal space (11) of the storage body (10) with a connection line (32) that permits the flow of medium, the gas vessel (30) and/or the storage body (10) and/or the connection line (32) has a valve (33) that influences the flow of medium between the gas vessel (30) and the storage body (10). The characteristic feature of the invention is that when the fire extinguishing apparatus is in a condition ready for use, more than 94% of the internal space (11) of the storage body (10) is filled with fire extinguishing material composition (1), where the composition (1) has a liquid and a gaseous component, and at least a part of the external surface (12) of the storage body (10) is surrounded by a material that reduces temperature fluctuations(5).
