What are 'quick response' heads characterized by?

Quick response heads in fire sprinkler systems are characterized by their small diameter glass bulbs and lower activation temperatures. This design allows them to respond more rapidly to a fire compared to standard response heads. The smaller glass bulbs contain a heat-activated liquid that expands and breaks the bulb at lower temperatures, typically around 155°F to 175°F, facilitating a quicker discharge of water over the fire. This attribute is essential for minimizing fire spread and damage in residential and commercial settings.

In contrast, other types of sprinkler heads may have larger bulbs or are designed for different activation mechanisms, which can lead to a delayed response in the event of a fire. Understanding the features and characteristics of quick response heads is crucial for effective fire protection system design and implementation.
