Which option describes the defined discharge pattern concept?

• A. Predetermined, fixed, or adjustable pattern
• B. Random pattern
• C. Manual only
• D. Automatic only

Answer: (A)

The defined discharge pattern is about how the foam-water spray is distributed over the protected area. It means the pattern is planned in advance and described in the design, and it can be fixed or adjustable to fit the space and hazard. This ensures the discharge covers the target area consistently and predictably. A random pattern would lead to uneven coverage and gaps, while “manual only” or “automatic only” refer to how the system is actuated, not to the distribution pattern itself.
