MONITORING AND EXTINGUISHING DEVICE
The invention relates to a device for monitoring and controlling the extinction of a source of fire or the like in a conveyed material flowing in a pipeline, in which device sources of danger are detected by means of a sensor system and controlled by introducing a fire extinguishant via extinguishing nozzles embedded in the pipe wall. For this purpose, a main controller and a large number of decentralised monitoring devices are provided for monitoring the functioning of each valve unit and of an extinguishing nozzle that is connected downstream to the valve of each valve unit and is to be supplied with the fire extinguishant. In the process, feedback is sent from the monitoring device to the central main controller.
