What is the primary benefit of using glass bulb sprinkler heads?

• A. They are easier to install
• B. They provide reliable activation via thermal expansion
• C. They are more cost-effective
• D. They require less maintenance

Answer: (B)

The primary benefit of using glass bulb sprinkler heads lies in their reliable activation mechanism that employs thermal expansion. Each glass bulb is filled with a liquid that expands when heated. As the temperature rises due to a fire, the liquid expands and eventually causes the glass bulb to shatter. This release allows water to flow from the sprinkler head and dampen the fire. The reliability of this activation process means that glass bulb sprinkler heads can respond quickly and effectively to temperature changes, which is crucial in fire situations. This thermal expansion method has been tested and proven over time, making it a trusted choice in fire protection systems. Other options, while relevant considerations in choosing sprinkler heads, do not emphasize the core functionality that makes glass bulb heads especially effective in activating water discharge during a fire. The thermal activation mechanism is central to their design and operation, underscoring why this aspect is the primary benefit.
