Which type of fire protection system is installed in occupancies where it is impractical or impossible to maintain water storage for fire protection?

• A. Stationary fire pumps
• B. Class I standpipe system
• C. Public fire alarm systems
• D. Smoke management system

Answer: (A)

When it's impractical to maintain on-site water storage for fire protection, a pumped water supply is used to ensure reliable flow to the system. A stationary fire pump is installed to boost pressure and deliver water from a source (like a city main or other external supply) into the sprinkler or standpipe network. This arrangement, governed by NFPA 20, allows the system to operate effectively without stored water by automatically starting to provide the required pressure and volume when demand increases or pressure drops. The pump can be electric or diesel and is positioned in a fixed location, ready to supply water when needed. The other options address alarms or smoke control or are components of different types of systems, but they do not solve the issue of providing a consistent water supply without on-site storage.
