Which guideline provides guidelines for positioning sprinklers to avoid obstructions in residential sidewall installations?

• A. Sprinkler Positioning Table
• B. Elevation View
• C. SI Units Conversion
• D. Foyers Protection

Answer: (A)

The guideline focuses on how to place sidewall sprinklers so the spray isn’t blocked by nearby objects. In NFPA 13R, the Sprinkler Positioning Table provides the specific offsets and clearances from walls and other potential obstructions to ensure the spray pattern develops properly and the protected area is covered. This table translates the room layout into practical placement rules, preventing situations where furniture, trim, or corners would interfere with discharge. The elevation view shows vertical placement but doesn’t give the obstruction-clearance details needed for sidewall heads. SI units conversion is just about changing measurement units, not about where to position sprinklers. Foyers protection deals with a particular area design concern rather than general obstruction-free placement.
