During the dry pipe valve test, what state must the quick opening device be in?

• A. Out of Service
• B. In Service
• C. Standby
• D. Activated

Answer: (B)

During a dry pipe valve test, the quick opening device must be in service so it can participate in the charging sequence like it would in normal operation. The QOD is designed to rapidly admit water into the dry pipe system once the valve opens, helping verify that water reaches the piping quickly and reliably. If the device were out of service, standby, or already activated, the test wouldn’t reflect how the system behaves during actual operation, and you wouldn’t be validating the normal response of the dry pipe valve and the water flow path. Keeping the quick opening device in service ensures the test measures the intended automatic response and water delivery.
