Under which scenario are automatic valves in fire suppression systems not tested?

Under which scenario are automatic valves in fire suppression systems not tested?

• A. The system discharges after a manual release.
• B. The system is in a shutdown mode.
• C. Activation releases the discharge agent.
• D. The valve fails closed during testing.

Answer: (C)

Automatic valves are tested under conditions that do not involve releasing the extinguishing agent. If the activation actually releases the agent, the system is already in an active discharge state, so performing a test at that moment would be inappropriate. It would dump agent, contaminate the environment, and obscure the test results, defeating the purpose of the test. Tests are conducted in safe, controlled states (such as shutdown or test modes) or using simulated signals that verify valve operation without discharging agent.
