How often must quick opening devices be tested?

• A. Every 1 year
• B. Every 2 years
• C. Every 3 years
• D. Every 5 years

Answer: (A)

Quick opening devices control the rapid admission of water into the system, so their reliability is essential for delivering water when a fire starts. They must be tested every year to confirm they operate properly, reset correctly after actuation, and show the proper indication. Over time, mechanical parts can stick, seals can wear, or components can become misaligned, and annual testing catches these issues before a fire occurs. Testing less often increases the risk that a defect goes unnoticed and could delay water flow during an emergency. Therefore, annual testing is the required frequency.
