Residential sidewall sprinklers are installed on which surface for fire protection?

• A. On ceilings
• B. On floors
• C. On corners
• D. On walls

Answer: (D)

Within residential sprinkler designs, sidewall sprinklers are mounted on walls. Mounted high on a vertical surface near the ceiling, the sprinkler’s deflector directs a horizontal spray across the room to cover the area below from the wall outward. This arrangement suits residential layouts with low or obstructed ceilings, keeps heads out of sight, and still provides effective coverage along the room’s perimeter.
