Sprinkler heads are rated by their release mechanisms, mounting positions, and which of the following?

• A. Color
• B. Release temperatures
• C. Size
• D. Brand

Answer: (B)

Sprinkler heads are specified by the temperature at which they release water, the release temperature. The release mechanism (how it triggers) and mounting position (upright or pendent) are separate design aspects, but the critical rating that determines when the head will discharge is the release temperature. This rating ensures the head activates at the appropriate ambient temperature, avoiding premature release or failure to activate. Color, size, or brand aren’t the activation rating—they don’t define when water is released.
