Which sprinkler type is appropriate for installation on walls to improve coverage?

• A. Sidewall Sprinklers
• B. Pendent Sprinklers
• C. Upright Sprinklers
• D. Concealed Sprinklers

Answer: (A)

Sidewall sprinklers are designed specifically for mounting on walls to extend and improve coverage along the perimeter of a room. Their spray deflector directs water outward from the wall, so the pattern reaches into the room and along the wall line, reducing dead spots that can occur with ceiling-mounted heads and making effective coverage easier in spaces with obstructions or tight ceiling areas. This wall-mounted configuration is why they’re the best choice when the goal is to improve coverage along walls.

Pendent sprinklers hang from the ceiling and mainly serve open-ceiling areas; they don’t optimize wall coverage as effectively. Upright sprinklers mount on top of piping and spray downward, often used in areas with obstructions above, not for wall-focused coverage. Concealed sprinklers are ceiling-mounted and hidden behind a decorative cover, so they don’t enhance wall coverage either.
