Which soffit width triggers different sprinkler placement rules?

Which soffit width triggers different sprinkler placement rules?

• A. 8 inches or less
• B. Over 8 inches
• C. Over 12 inches
• D. Over 6 inches

Answer: (B)

The key idea is that obstructions like soffits affect how water from a sprinkler spreads. When a soffit is wide enough, it can block or divert the spray and create dead zones, so the placement rules must be adjusted to maintain coverage. The threshold used in this context is eight inches; if the soffit is wider than eight inches, you switch to a different placement approach to ensure the area beneath and around the soffit is adequately covered. Soffits eight inches or less don’t trigger the special change, while larger than eight inches does. The exact thresholds of 12 inches or 6 inches aren’t the specified trigger for this rule.
