Where are the main sprinkler system valves usually installed?

• A. At the fire pump
• B. On the roof
• C. In the basement
• D. On the main riser, above the water supply control valve

Answer: (D)

The main sprinkler system valves are typically installed on the main riser, above the water supply control valve. This location is critical for several reasons. Placing the valves on the riser allows for easy access and control over the entire sprinkler system, making it simpler for firefighters and maintenance personnel to manage the system during emergencies and routine checks. Positioning the valves above the water supply control valve ensures that the system can be effectively managed while maintaining pressure and flow throughout the system. If valves were located elsewhere, such as in the basement or on the roof, it could complicate access during emergencies, delay response times, and lead to potential safety hazards. The main riser serves as a centralized point for the system, making it the ideal location for these critical components.
