What is the temperature rating for a yellow bulb?

• A. 135
• B. 155
• C. 174
• D. 200

Answer: (C)

The temperature rating for a yellow bulb, which is part of fire alarm and sprinkler systems, is typically 174 degrees Fahrenheit. This designation indicates that the bulb will activate at that specific temperature, triggering the sprinkler system to release water and help control or extinguish a fire. In fire safety applications, different colored bulbs correspond to different temperature ratings. A yellow bulb is often used in environments where a moderate temperature threshold is appropriate, providing an effective balance between too low and too high a response to fire conditions. Understanding these ratings is crucial for ensuring that fire protection systems function effectively in various scenarios.
