Alarm valve station of a fire extinguishing system, in particular a sprinkler or spray water extinguishing system, and fire extinguishing system

An alarm valve station of a fire extinguishing system, comprising:

• a fire extinguishing system valve that feeds a plurality of sprinkler nozzles, comprising a housing which has a fluid inlet chamber, a fluid outlet chamber and a closing body reciprocable between a blocking state and a release state, wherein the fluid inlet chamber and the fluid outlet chamber are separated from each other in the blocking state and communicate with each other in fluid-conducting relationship in the release state to flow a fire extinguishing fluid from the fluid inlet chamber to the fluid outlet chamber,
• an alarm passage in fluid communication with at least one of the fluid inlet and fluid outlet of the housing, and
• an electronic evaluation unit which is integrated in the housing, arranged externally on the housing or arranged in the proximity of the fire extinguishing system valve,
• wherein the evaluation unit
• is connected in signal-conducting relationship to one or more actuators associated with at least one of the closing body and the alarm passage, and
• is adapted to control the actuator or actuators by the control commands, wherein
• the alarm valve station has one or more sensors that monitor at least one of the fluid inlet chamber, the fluid outlet chamber, the closing body, and the alarm passage, 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.
