Which statement about temperature ratings for factory-painted sprinklers is true?

• A. White paint indicates low temperature rating
• B. White paint indicates intermediate temperature rating
• C. White paint indicates high temperature rating
• D. White paint indicates very high temperature rating

Answer: (B)

Color coding on factory-painted sprinklers is used to show the temperature rating at which the head will operate, giving installers a quick visual cue of the heat threshold. White is used to signal an intermediate temperature rating, placing it in the middle of the range rather than at the low or high end. This helps ensure the sprinkler activates at a moderate ambient temperature appropriate for a wide range of environments. Other colors denote the lower or higher ratings, so white specifically represents the middle category.
