Which type of foam system is characterized by fixed nozzles with permanently installed pumps that pipe foam from a central location?

• A. Fixed system
• B. Portable system
• C. Mobile system
• D. Self-contained system

Answer: (A)

Fixed foam systems install the components into the building: there is a network of permanent piping, fixed nozzles, and a pump that is also permanently installed, pushing foam concentrate from a central location through the system. This setup allows foam to be discharged from a central point to multiple nozzles without bringing equipment to the scene. Portable systems rely on movable equipment, mobile systems are mounted on a vehicle, and self-contained systems carry everything on one unit rather than a building-wide fixed piping network, so they don’t match the description.
