Which heads are typically used in mechanical rooms or other inaccessible spaces and spray in a half-circle pattern?

• A. Pendant Sprinkler Heads
• B. Upright Sprinkler Heads
• C. Side Wall Heads
• D. Ball Cartridge Heads

Answer: (C)

Sidewall heads are designed to project water horizontally into the room from a wall, creating a half-circle spray pattern away from the wall. This makes them ideal for mechanical rooms or other spaces where the ceiling is inaccessible or crowded, because you can mount them high on the wall and still achieve effective coverage in front of the wall without relying on ceiling space. The half-circle spray pattern is the key feature that fits these layouts. Pendant heads hang from the ceiling and spray downward in a broad pattern, upright heads project water around from a vertical pipe, and ball cartridge refers to the internal mechanism rather than the spray pattern or mounting location, so they don’t match the need for a half-circle coverage in an inaccessible space.
