250°F

The bulb color blue is indicative of high-temperature sprinklers that activate at a temperature of 250°F. This classification is crucial for ensuring that the sprinkler system functions effectively in environments that may reach elevated temperatures. High-temperature sprinklers are designed for use in areas such as warehouses, factories, or other industrial settings where higher heat levels may be present.

Understanding the bulb colors and their corresponding temperatures allows sprinkler fitters and technicians to select the appropriate sprinklers for specific applications, ensuring safety and compliance with fire protection standards. Each color corresponds to a predetermined activation temperature, so selecting blue for 250°F is essential to provide optimal fire suppression in high-risk areas. This ensures that the sprinkler system activates at the correct time to control or extinguish a fire, thereby protecting property and lives.
