Which term describes systems designed for fire detection and control?

• A. Bar
• B. Flashover
• C. Fire sprinkler systems
• D. Scope of standard

Answer: (C)

Systems designed to automatically detect heat and control a fire by releasing water through sprinkler heads are fire sprinkler systems. In NFPA 13R, these low‑rise residential systems provide automatic protection by delivering water to suppress or control a fire, helping occupants escape and supporting firefighters. While fire alarms (detection) are a separate concept, the sprinkler system itself activates when heat at a sprinkler head reaches its threshold, combining detection (heat-triggered activation) with control (water discharge). The other terms don’t describe a system intended to detect and control fires: a bar is not related to fire protection, flashover is a dangerous fire growth stage, and the scope of a standard refers to what the document covers rather than a type of protective system.
