What is the purpose of a quick opening device?

• A. Speed the opening of a dry pipe valve
• B. Increase the system capacity served by a single dry pipe system
• C. All of the above
• D. Speed the delivery of water to a fire

Answer: (C)

A quick opening device is used to reduce the delay between a sprinkler being activated and water actually entering the system. By helping the dry-pipe valve move to the open position more quickly, water begins to flow into the piping sooner, which directly speeds up both the opening process and the delivery of water to the fire. Because water reaches the system sooner, the effective amount of water available to be delivered in the crucial early moments of a fire is increased, which can be described as increasing the system’s usable capacity during an incident. For these reasons, all of the above statements describe the purpose of a quick opening device.
