[origin: WO2019063373A1] The invention relates to a dry alarm valve station of a fire-extinguishing facility. According to the invention, the dry alarm valve station comprises an alarm valve, an alarm line connected to the alarm valve, an alarm mechanism, preferably comprising an alarm pressure switch, which is connected to the alarm line and designed to trigger an alarm signal when a pre-determined fluid pressure is reached in the alarm line, and comprises a pressure-operated valve which is connected between the alarm mechanism and the alarm valve, is controlled by means of a control chamber and designed to block the alarm line as long as the pre-determined control pressure is reached in the control chamber, and to release same when the pre-determined control pressure is not reached in the control chamber.
