Where should the normal manual actuation controls be located?

• A. In a locked cabinet.
• B. For easy accessibility at all times, including at the time of a fire.
• C. Only in the control room.
• D. On the roof.

Answer: (B)

Manual actuation controls for a total-flood clean agent system must be readily accessible to occupants and responders at all times, including during a fire, so the system can be discharged quickly if automatic detection isn’t triggered or needs to be overridden. Placing the control in a locked cabinet would impede rapid access when time matters, and locating it only in the control room or on the roof creates unnecessary barriers during an emergency. The goal is clear, immediate access to initiate discharge from a convenient, reachable location that is protected from smoke and heat but still accessible when a fire is occurring.
