In a dry pipe system, during testing, the quick opening device must be in what state?

• A. In Service
• B. Standby
• C. Open Only During Test
• D. Locked Out

Answer: (A)

The quick opening device should be in service. In a dry pipe system, this device provides a fast path for water to enter the dry piping when charging or testing the system. Having it in service ensures water can reach the dry pipe quickly and the test can pressurize properly to verify leaks and operation. If the device were locked out or not in service, the system wouldn’t fill or pressurize correctly, making the test unreliable. It isn’t limited to “open only during test” because it’s part of normal operation too, and needs to be ready for testing as well.
