• D. Positioning is at the discretion of installer

Answer: (C)

Sprinkler placement must follow specific guidelines about how far the heads sit from walls and from objects that could block or deflect spray. In NFPA 13R, these clearances are critical to make sure the spray pattern reaches the protected area and that the system’s hydraulics behave as intended in low-rise residential buildings. Obstructions like walls, cabinets, or decorative features can create dead zones or shadow areas if a head is placed too close to them or in a configuration that blocks distribution. Adhering to these guidelines ensures reliable coverage and minimizes the risk of under- or over-watered areas. Aesthetics or personal discretion do not substitute for the required placement rules, as they must conform to the standard’s specifications for walls and obstructions.
