Extinguishing system and method for extinguishing fires

A method for extinguishing fires, the method comprising steps of:

• providing an extinguishing system for extinguishing fires, the extinguishing system comprising:
• a pump system for pumping an extinguishing agent;
• one or more nozzles connected operatively to the pump system for spraying the extinguishing agent at a source of fire;
• a supply or inlet arranged on the pump system for supplying the extinguishing agent to the pump system;
• one or more extinguishing conduits with respective extinguishing lengths arranged on the pump system for supplying the extinguishing agent to the one or more nozzles;
• and
• an extinguishing controller provided with an input system that provides system data supplied by a user, wherein the system data comprises data about the one or more extinguishing conduits, data about the pump system, and data about the one or more nozzles, the data about the one or more extinguishing conduits comprising:
• a quantity of the one or more extinguishing conduits;
• and
• a length and/or diameter of each of the one or more extinguishing conduits;
• the extinguishing controller further comprising a feedforward component configured to determine an operating pressure on the basis of the system data obtained by the input system;
• installing the extinguishing system;
• activating the extinguishing system, comprising supplying the system data to the input system, including data about the extinguishing conduit, the pump system, and the one or more nozzles;
• and
• determining, using the feedforward component of the extinguishing controller, an operating pressure at the one or more nozzles based on the system data to control the pump system.
