Which term describes the maximum coverage area for sprinkler systems?

• A. Area of design
• B. Protective caps
• C. Temperature ratings
• D. Sprinkler painting

Answer: (A)

The maximum area a sprinkler system is designed to cover is known as the area of design. This boundary defines the largest floor area over which the chosen design density must be maintained by the system, so the sprinklers and piping are laid out to guarantee the required water distribution within that space. In practice, the area of design is used to determine how many sprinklers are needed and how the piping is arranged to meet the protection criteria. Protective caps are construction aids, temperature ratings tell you when a sprinkler activates, and sprinkler painting isn’t a term used to describe coverage.
