Which system is an automatic or manually actuated fixed pipe system that provides a specific discharge and distribution over the protected surfaces or area?

• A. Deluge sprinkler system
• B. Dry pipe system
• C. Pre action system
• D. Water spray system

Answer: (D)

Water spray systems are a fixed network of pipework with spray nozzles that release water in a defined spray pattern across the protected area. They can be activated automatically or manually. This arrangement provides a specific discharge and targeted distribution over surfaces, which is essential for covering the protected area in a controlled way. Other systems differ in how water is released: deluge systems open all heads so water flows from every nozzle at once; dry pipe systems hold pressurized air or inert gas and fill with water after a head releases; pre-action systems require a triggering event before water enters the system. This combination of fixed piping and spray-nozzle distribution aligns with the description of a water spray system.
