Which classification applies when the maximum ceiling temperature is 225°F (107°C)?

Explanation:
The main idea here is how NFPA 13R groups ceiling temperatures into categories to guide sprinkler selection. The ceiling temperature classification tells you the environment temperature the system must handle and helps ensure the sprinkler’s temperature rating matches that ceiling heat. A maximum ceiling temperature of 225°F (107°C) falls in the intermediate category, which is defined for ceilings that can reach around that range. The high category is for hotter ceilings, while the low and ordinary categories cover cooler ceilings. So, 225°F fits best with the intermediate classification.
