Coverage criteria specify what?

Coverage criteria specify what?

• A. System wiring requirements
• B. Pressure rating requirements
• C. Specifications for sprinkler coverage areas
• D. Thermal sensitivity requirements

Answer: (C)

Coverage criteria define the area that each sprinkler head is expected to protect—the sprinkler’s coverage area. This guides how you space and place heads to ensure the protected space receives adequate water when a head operates. In NFPA 13R for low-rise residential systems, the design centers on making sure each head can cover its assigned area, taking into account ceiling shape, obstructions, and any required head spacing, so the overall protection meets code requirements. The other topics referenced aren’t about how much area a head should cover. Wiring requirements relate to electrical or control systems, pressure rating requirements concern how much pressure the system must deliver, and thermal sensitivity requirements pertain to the sprinkler’s temperature rating and response, not the geographic coverage per head.
