At least ______ manual actuator shall be provided for each system.

At least ______ manual actuator shall be provided for each system.

• A. Two
• B. One
• C. Zero
• D. Several

Answer: (B)

The concept being tested is that a wet chemical fire suppression system must have an accessible manual activation option. There should be at least one manual actuator for each system so that occupants can trigger the extinguisher independently of any automatic components if a fire occurs. Having at least one actuator ensures a quick, direct way to deploy the agent when time is critical. The actuator is typically a readily reachable pull device or switch located near the hood or outside the protected area, allowing staff to activate the system without relying on automatic sensors alone. There’s no requirement for two or more per system in normal practice; zero would leave no manual option, while several isn’t mandated unless the specific installation justifies it.
