Sprinkler Positioning Table provides guidelines for placement to avoid obstructions.

Sprinkler Positioning Table provides guidelines for placement to avoid obstructions.

• A. Shadow areas
• B. Elevation View
• C. SI Units Conversion
• D. Sprinkler Positioning Table

Answer: (D)

The main idea is that a Sprinkler Positioning Table is the tool used to determine where sprinklers should be placed so that obstructions don’t block or distort the spray. This table provides specific distances from ceilings, walls, beams, ducts, and other objects, so the water pattern remains unobstructed and the required coverage and clearance are met. Why this is the best answer: the table is built for evaluating and preventing interference from nearby features, reducing shadowed or dead zones where water might not reach. It directly translates room features into practical placement guidelines to preserve performance and meet NFPA 13R requirements. The other options don’t fit as placement guides. Shadow areas describe the result of obstructions rather than a guideline tool you use to place sprinklers. An Elevation View shows vertical positioning or heights, not how to avoid obstructions in the spray pattern. SI Units Conversion is about converting units, not about where to position sprinklers to avoid interference.
