Which statement about architectural feature spacing in sprinkler design is true?

• A. Decorative features have no impact on sprinkler spacing.
• B. Spacing is determined solely by aesthetic considerations.
• C. Distance from architectural features to sprinklers must meet spacing.
• D. All architectural features must be avoided when placing sprinklers.

Answer: (C)

In NFPA 13R design, keeping a defined distance between sprinklers and architectural features is a performance requirement. Decorative and architectural elements can obstruct or deflect the water spray, create shadowed areas, or alter the coverage pattern, so the installation must meet specified clearances.

The statement that the distance from architectural features to sprinklers must meet spacing is the best answer because it reflects this clearance requirement, ensuring reliable sprinkler performance rather than relying on aesthetics or assumptions.

Decorative features do affect spray, so spacing isn’t determined by appearance alone. It isn’t required to avoid every feature outright; you just need to maintain the code-prescribed clearances to avoid interference and ensure proper coverage.
