What is the temperature rating for an orange bulb?

• A. 135
• B. 155
• C. 174
• D. 200

Answer: (A)

The temperature rating for an orange bulb is 135°F. This specific rating indicates that the bulb is designed to activate at this temperature, triggering the sprinkler system to release water in the event of a fire. Understanding the temperature ratings of sprinkler bulbs is crucial for effective fire protection, as it ensures that the system activates when needed, providing an early response to fire incidents. The orange bulbs are commonly used in applications where a moderate level of heat is expected, providing a balance between sensitivity and response time. If the surrounding temperature exceeds the bulb's rating, it will activate the sprinkler, thus helping to control or extinguish the fire before it develops further.
