Abstract: The present invention relates to a fire detection system arranged for detecting fire by detecting a pressure drop in a detection conduit (15) caused by rupture of the detection conduit (15). The system comprises a detection fluid container (13) for holding a pressurized detection fluid, the detection conduit (15) which is connected to the detection fluid container (13), and a valve assembly controlling the supply of detection fluid from the detection fluid container (13) to the detection conduit (15).
Abstract: The present invention relates to a fire extinguishing system comprising a fire extinguishing medium container (3), a first (5) and second (7) fire extinguishing sub-systems, and a valve assembly (9) fluidly connecting the fire extinguishing medium container (3) to each of the first (5) and second (7) fire extinguishing sub-systems.
Abstract: The present invention relates to a fire extinguishing system comprising a pressurized detection conduit (115), an extinguishing line (108) separate from the detection conduit (115), and a control module (105) adapted for sensing a pressure drop in the detection conduit (115) and for opening supply of extinguishing medium from a storage (103) to the extinguishing line (108). The detection conduit (115) is gas-permeable and filled with a detection liquid. The fire extinguishing system further comprises a liquid-gas interface (117) fluidly connecting the detection conduit (115) to a pressurized gas source (103, 106), wherein the liquid-gas interface (117) comprises an interface container (123) defining a gas space (131) which communicates with the pressurized gas source (106) and a liquid space (133) which communicates with the detection conduit (115).
