What is the bulb color for high-temperature sprinklers?

High-temperature sprinklers are identified by their blue bulb color. This designation helps differentiate them from other types of sprinklers that are calibrated for lower temperature ranges. The blue bulb specifically indicates that the sprinkler is designed to activate at elevated temperatures, typically above 200 degrees Fahrenheit.

This is crucial for installations in areas where higher ambient temperatures are expected, such as in industrial facilities or warehouses. Utilizing the correct bulb color ensures that the sprinklers will function as intended under critical conditions, providing effective fire suppression when needed.

In summary, the blue bulb signifies that the sprinkler is capable of operating effectively in high-temperature environments, ensuring safety and compliance with fire protection standards.
