Which pairing is correct for bulb color and temperature rating?

• A. Orange-200
• B. Red-135
• C. Yellow-174
• D. Green-174

Answer: (C)

The pairing of yellow bulbs with a temperature rating of 174 degrees Fahrenheit is recognized as a standard in fire sprinkler systems. In these systems, different colors of bulbs indicate specific temperature thresholds, which are critical for the appropriate operation of sprinklers in fire situations. Yellow bulbs are generally used for temperatures of 174 degrees because they are designed to activate in response to fires where such heat levels could occur. This ensures that the sprinkler system will engage at the right time to control the fire, making it a crucial safety feature. Understanding the color coding system helps in the maintenance and installation of fire protection systems, ensuring that all components function as intended under various temperature conditions.
