How does a deluge sprinkler system function?

A deluge sprinkler system is specifically designed to release large volumes of water over a designated area simultaneously when activated. This system is commonly used in high-hazard environments, such as industrial facilities or areas where rapid fire spread can occur.

Upon activation, all sprinklers in the system open at once, delivering water to the entire protected area, which helps to effectively suppress or control a fire before it can spread further. This immediate and comprehensive application of water helps to reduce heat and extinguish flames quickly, which is crucial in situations where fire intensity can escalate rapidly.

The other options describe operations that either do not apply to a deluge system or do not provide the necessary fire suppression capabilities. For instance, the idea of spraying a fine mist or releasing small amounts of water intermittently would not be effective in quickly controlling a large fire scenario. Similarly, the method of activating one sprinkler at a time does not reflect the operational design of deluge systems, which prioritize immediate and widespread water delivery for maximum impact.
