The intermediate temperature classification of sprinklers corresponds to ratings for what level of heat exposure?

• A. Sprinklers rated for low heat exposure.
• B. Sprinklers rated for high heat exposure.
• C. Sprinklers rated for mild heat exposure.
• D. Sprinklers rated for moderate heat exposure.

Answer: (D)

Sprinkler temperature ratings show the heat level needed to activate the device. The intermediate rating is the mid-range, meaning it’s designed for moderate heat exposure—higher than what’s considered mild or low, but not as high as the areas that require a high rating. In practice, an intermediate-rated sprinkler is used in spaces that can get warmer than normal rooms but aren’t extreme heat sources, providing activation at a middle ground of heat exposure.
