Abstract
The invention relates to a control system () of a fire-extinguishing installation, having at least one control line () for controlling a controlling procedure of the fire-extinguishing installation, wherein the control line () in a passive operation is unpressurized and the control line () in a control operation is impinged with a control pressure, and a safety device (), fluidically connected to the control line (), having a pressure equalization chamber () in which a holding element () and a movable closure element () are disposed. It is proposed that the closure element () is disposed in the pressure equalization chamber () so as to be displaceable between a first terminal position and a second terminal position, and the holding element () is configured for exerting on the closure element () a restoring force in the direction of the first terminal position, wherein the restoring force on the closure element () in the second terminal position of the closure element () is higher than the weight force of the closure element (), and in the first terminal position of the closure element () is lower than a pressure force that in the control operation acts as a function of the control pressure on the closure element ().
