Abstract: A system for reducing the oxygen content in the spatial atmosphere of an enclosed area and/or for maintaining a reduced oxygen content in the spatial atmosphere of an enclosed area below a predefined and reduced operating concentration in comparison to the oxygen concentration of the normal ambient air. The system includes a gas separation system to that end, the outlet of which is fluidly connected to the enclosed area in order to continuously supply an oxygen-reduced gas mixture or oxygen-displacing gas. The gas separation system is configured such that the oxygen concentration in the spatial atmosphere of the enclosed area always remains in a range between the predefined operating concentration and a predefined or definable lower limit concentration during a continuous operation of the gas separation system.

Abstract: The present invention relates to a system as well as a method for extinguishing fire in an enclosed room (6) in which the enclosed room (6) is flooded with extinguishing gas at least until an extinguishing gas concentration capable of providing an extinguishing effect (a) is set in the flood zone. In order to achieve the realizing of a maximum extinguishing gas concentration (b) as quickly as possible without the flooding of the room (6) thereby posing a danger to people, it is inventively provided for the flooding of the enclosed room (6) to be divided into a pre-flooding phase and a main flooding phase subsequent thereto. The pre-flooding phase corresponds to an interval of time between the time (t1) the alarming starts to warn people of impending danger and a predefined time (t2). The main flooding phase corresponds to an interval of time between the predefined time (t2) and the time (t4) at which a maximum extinguishing gas concentration (b) is reached. The enclosed room (6) is flooded such that during the entire pre-flooding phase, the concentration of extinguishing gas in the enclosed room (6) does not exceed a predefined or predefinable value for the extinguishing gas employed which is below the critical NOAEL value.

Abstract: A system for reducing oxygen in a target room, particularly for the purpose of controlling or preventing fire, wherein the system comprises an enclosed buffer space which is fluidly connectable or connected to the target room for the as-needed introduction of at least a portion of the room air of the buffer space into the target room. The system moreover comprises an oxygen-reducing mechanism allocated to the buffer space for setting and maintaining a reduced oxygen content in the spatial atmosphere of the buffer space compared to the normal earth atmosphere such that the oxygen content in the spatial atmosphere of the buffer space is lower than the oxygen content in the spatial atmosphere of the target room. The system moreover comprises a mechanism for introducing room air from the buffer space into the target room as needed.

Abstract: The invention relates to a oxygen reduction system as well as a method for operating an oxygen reduction system. The oxygen reduction system comprises an inert gas source and a line system which is fluidly connected or connectable to the inert gas source and to the at least one enclosed area in order to supply the gas provided by the inert gas source to the at least one enclosed area as needed. The invention provides for conducting a leak test on at least one section of the line system by pressure-testing the line section to be checked for tightness using at least a portion of the gas mixture or gas provided by the inert gas source.

Abstract: A device and a method for detecting scattered light signals is specified. A light source exposes a scattered light area in which particles may be present to light. With the objective of reducing costs and improving detection accuracy, the device comprises a plurality of optical sensors for detecting scattered light and an evaluation unit for evaluating the signals detected by the optical sensors, wherein the sensors are each arranged at a sensor angle relative to the incident axis of the incident light so as to detect scattered light from the scattered light area, wherein one of the plurality of optical sensors is a reference sensor, and wherein the evaluation unit is designed to relate the signal profiles of the other optical sensors to the signal profile of the reference sensor, wherein the signal profiles of the optical sensors serve in classifying any particles which may be present in the scattered light area.
