Abstract
Embodiments of the invention provide a redundant stationary fire fighting system and method for use in a structure coupled to a water supply and a main water pump(s) that generates a water stream. The system includes one or more water flow meters to measure the water stream and generate a water flow signal. The system includes a primary foam proportioning system and a redundant secondary foam proportioning system, each including a foam pump, a motor, a foam flow meter, and a controller. The controller is configured to automatically operate the foam pump based on the water flow signal in order to inject liquid foam concentrate directly into the water stream. The redundant secondary foam proportioning system can be automatically started in case of component failure in the primary foam proportioning system.
