Deflector Distance is the distance from the sprinkler deflector to which item?

• A. Maximum Allowable Distance
• B. Elevation View
• C. Deflector Distance
• D. Obstruction Height

Answer: (A)

Deflector distance refers to how far the water must reach from the sprinkler deflector to cover the space effectively, which is the farthest point that can be wetted within the design—this is defined as the maximum allowable distance. In other words, you measure from the deflector to the farthest point in the protected area that still needs to be reached by the spray, ensuring the coverage is adequate. Elevation view and obstruction height concern drawings or obstacle dimensions, not the spray reach. Calling the distance to the far edge of the coverage area the maximum allowable distance keeps the concept clear and ties directly to ensuring complete coverage.
