Which term denotes the categories of sprinkler systems as defined by standards?

• A. Classification of System Categories
• B. Types of Sprinklers
• C. System Types
• D. Categories of Standards

Answer: (C)

Standards classify sprinkler configurations using the term system types. This label covers the broad categories like wet-pipe, dry-pipe, and deluge configurations that define how water is distributed and controlled in the building. It’s the wording used in codes to group these different design approaches, rather than focusing on the sprinkler heads themselves or on arbitrary phrasing. The other options don’t reflect the standard terminology: describing sprinkler heads would be types of sprinklers, while phrases like classification or categories of standards aren’t how the standards categorize installations. So, system types is the correct term because it directly denotes the categories of sprinkler-system configurations defined by the standards.
