Abstract

An alarm valve station (80) of a fire extinguishing system (100) includes a fire extinguishing system valve (1) having a housing (2, 3) which has a fluid inlet chamber (8), a fluid outlet chamber (9) and a closing body (4a) reciprocable between a blocking state and a release state, wherein the fluid inlet chamber (8) and the fluid outlet chamber (9) are separated from each other in the blocking state and communicate with each other in fluid-conducting relationship in the release state. In particular it is proposed that the evaluation unit is connected in signal-conducting relationship to one or more actuators, and is adapted to control the actuator or actuators by the control commands, wherein the alarm valve station preferably has one or more sensors and the evaluation unit is connected in signal-conducting relationship to the sensor or sensors and is adapted to control the actuator or actuators in dependence on the sensor data present thereat.
