Which term describes specifications for sprinkler operational temperatures?

• A. Temperature ratings
• B. Sprinkler painting
• C. Horizontal ceilings
• D. Area of design

Answer: (A)

Sprinkler activation is governed by the temperature at which the sprinkler is designed to release water. This specification is called the temperature rating. Sprinklers are rated with a listed temperature (for example, 135°F or 165°F), which indicates the ambient temperature at which the sprinkler will activate. Choosing the correct temperature rating helps ensure reliable operation in the room’s typical temperatures and prevents nuisance activations or failure to discharge when needed. The other terms don’t describe when the sprinkler will activate: sprinkler painting is about finish, horizontal ceilings relate to layout, and area of design refers to coverage area.
