What is the maximum allowable distance between the ceiling and the deflector of a sprinkler below a non-combustible ceiling?

• A. 6 inches
• B. 8 inches
• C. 10 inches
• D. 12 inches

Answer: (D)

The maximum allowable distance between the ceiling and the deflector of a sprinkler installed below a non-combustible ceiling is 12 inches. This standard is established to ensure the effective operation of the sprinkler system. Sprinklers are designed to distribute water effectively throughout a designated area, and maintaining the correct vertical distance between the deflector and the ceiling plays a critical role in achieving optimal performance. If the deflector is placed too far from the ceiling, it can lead to inadequate coverage and reduced efficiency in extinguishing a fire. This distance allows for proper water distribution patterns to form, ensuring that the sprinklers will cover the intended area and suppress flames effectively. Adhering to this guideline is essential in ensuring safety standards are met and in maintaining the integrity of the fire suppression system.
