Abstract: Embodiments of the invention provide a fire extinguishing system including an electronic control unit in communication with a software library, a foam proportioning system including foam proportioning equipment, and a smart connector. The smart connector includes a controller, and the smart connector is connected to the foam proportioning equipment. The controller automatically initiates an authentication procedure when the smart connector is connected to the electronic control unit. The controller causes the electronic control unit to automatically unlock at least one routines in the software library after the authentication procedure is complete to enable control of the foam proportioning equipment.

Abstract: Embodiments of the invention provide a fire-extinguishing system and method for injecting foamant into a stream of water. The system can include a flow meter determining a flow rate of the stream of water and a foam pump having an inlet coupled to a supply of foamant and an outlet coupled to the stream of water. The system includes a servo motor driving the foam pump. The servo motor includes a sensor used to determine a rotor shaft speed and/or a rotor shaft torque.

The system includes a servo motor driving the foam pump. The servo motor includes a sensor used to determine a rotor shaft speed and/or a rotor shaft torque. A controller can control an operating speed of the servo motor using closed-loop control depending on the flow rate and the rotor shaft speed and/or the rotor shaft torque.

Abstract: A method and apparatus for installing a foam proportioning system into existing fire fighting equipment is provided. The method can include installing a foam proportioning library into a first application of a processor of the existing fire fighting equipment and installing a foam proportioning support into a second application of a display of the existing fire fighting equipment. The method can also include connecting a foam proportioner to the processor, receiving user inputs with the display, and processing the user inputs with the second application and the foam proportioning support. The method can further include transmitting the user inputs to the processor and operating the foam proportioner in response to the user inputs with the first application and the foam proportioning library.
