ABSTRACT OF THE DISCLOSURE There is described an electronic fire reporting and sprinkling control module to be connected to a control bus of a fire alarm system, and to a flow control valve which controls flow of extinguishing fluid into a sprinkler system. The sprinkler system can be monitored by pressurized air. The module comprises a bus connection, detector input connections, an air pressure detector connection to provide a status signal representative of pressure inside the sprinkler system, a detection mode unit having inputs connected to the detector input connections, a pre- programmed sprinkling mode unit for generating a sprinkler signal according to a pre programmed operation mode and the status signal present at the air pressure input connection, a timer for initiating sprinkling periods as long as its input is activated, and a valve control unit having a first input for receiving an output signal from the timer, and an output for activating the flow control valve, whereby information concerning a fire emergency can be directly transmitted to the fire alarm system by means of the control bus connection, whereby fire emergency conditions in an area can be set by means of a group of detectors and the detection mode unit, and whereby automatic sprinkling periods can be programmed by means of the timer. There is also described a flow control valve system, and a method of controlling the flow control valve.
