What temperature range is associated with a red sprinkler bulb?

• A. 60 to 68 °C
• B. 57 °C
• C. 79 °C
• D. 93 °C

Answer: (A)

A red sprinkler bulb is specifically calibrated to activate at a temperature range of 60 to 68 °C. This range is critical for efficient fire suppression, as it allows the sprinkler system to respond effectively to heat generated by a fire, ensuring that the fire can be controlled as quickly as possible. The color coding system for sprinkler bulbs is standardized, where different colors correspond to specific activation temperatures. Understanding these temperature classifications is essential for selecting appropriate sprinklers for various applications in accordance with NFPA 13 standards.
