What is the temperature rating for a green bulb?

• A. 135
• B. 155
• C. 174
• D. 200

Answer: (D)

The temperature rating for a green bulb in fire alarm and sprinkler systems is 200 degrees Fahrenheit. This rating is crucial because it indicates the temperature at which the bulb will burst and activate the sprinkler system. Green bulbs are typically used in areas where a higher level of heat may be expected, such as areas near heat-producing equipment or in environments with elevated ambient temperatures. Understanding the temperature ratings of bulbs is essential for effective fire protection, as it helps ensure that sprinklers operate at the appropriate time to control or extinguish a fire. Each color-coded bulb corresponds to a specific activation temperature, and using the correct bulb in the right application is key to maximizing safety and compliance with fire codes.
