Which term refers to systems designed for fire suppression using sprinklers?

• A. Listing Limitations
• B. Automatic Sprinkler Installations
• C. Corrosion Inhibitors
• D. Light Hazard Occupancies

Answer: (B)

Automatic Sprinkler Installations are fire suppression systems that automatically discharge water through sprinkler heads in response to heat, providing immediate protection without human action. This automatic operation is the key feature that defines systems designed for fire suppression using sprinklers. In NFPA 13R, these installations cover the various sprinkler configurations used in low-rise residential buildings, such as wet-pipe or dry-pipe setups, all centered on automatic activation at the sprinkler head. The other terms refer to different concepts—listing limitations deal with product approvals and labeling, corrosion inhibitors are chemicals to protect piping, and light hazard occupancies describe a classification affecting design but not the system type itself.
