<p>The system comprises a main network situated downstream from a check valve that supplies the sensors, for example, in the form of sprinklers. This main network is subdivided into secondary networks, each secondary network being isolated from the main network by a valve that enables water to be prevented from entering the portions of the network in which it is not needed. The valve is capable not only of compensating for losses in pressure in the network but also for opening itself completely when a fire is detected.</p> |
