Which term describes the distance from the sidewall to sprinkler?

• A. From sidewall to obstruction
• B. From ceiling to sprinkler
• C. Maximum Allowable Distance
• D. From sidewall to sprinkler

Answer: (C)

In NFPA 13R design, the distance from a sidewall to a sprinkler is described by the Maximum Allowable Distance. This term defines the greatest spacing you can have between the sidewall and the sprinkler while still achieving the required coverage along the wall. Keeping within this maximum ensures the sprinkler’s spray pattern reaches the protected area near the wall and meets the design criteria. Other phrases describe different relationships (like the literal distance from wall to sprinkler or vertical distances), but the standard term for the wall-to-sprinkler limit is Maximum Allowable Distance.
