In a dry pipe system, water is not present in the pipes until a fire occurs and a sprinkler is activated. When the sprinkler opens, the system must quickly fill the pipes with water to start discharging it. Quick opening devices are specifically designed to reduce the time it takes for water to start flowing from the system following the activation of the sprinkler. By allowing air to escape more rapidly, these devices enable the water to flow sooner, thus minimizing any delay in water discharge during a fire emergency.

Quick opening devices include specialized valves or mechanisms that can open more rapidly than standard control valves, making them essential for improving the response time of the fire suppression system. This is particularly critical in situations where immediate fire control is necessary to limit damage and ensure safety.

The understanding of how water delivery systems operate and the role of various components in optimizing their performance is crucial for effective fire safety management.
