What does the maximum protection area define?

• A. The Maximum Water Pressure at the Supply.
• B. The Maximum Number of Sprinklers per Room.
• C. The Limit on Area Each Sprinkler Can Protect.
• D. The Pipe Diameter.

Answer: (C)

The maximum protection area is the limit on the area that a single sprinkler head is expected to protect under the design. In a residential sprinkler layout, each head is allowed to cover only a certain sized area to ensure adequate water distribution and reliable response. If a space is larger than this limit, additional sprinklers are needed so that no one sprinkler has to protect more area than its design allows. This concept helps guide sprinkler spacing and the number of heads in a given space, and it’s not about water pressure, the number of sprinklers per room, or pipe diameter.
