During system maintenance of a clean agent system, it is common practice to remove the solenoid operated actuator from the agent storage container discharge valve.

During system maintenance of a clean agent system, it is common practice to remove the solenoid operated actuator from the agent storage container discharge valve.

• A. Not applicable
• B. Only during commissioning
• C. True
• D. False

Answer: (C)

During maintenance, isolating the discharge valve from its electrical actuation prevents any chance of an unintended release. The solenoid operates the valve when a control signal is received, so removing the solenoid outright eliminates the possibility that wiring faults, stray voltages, or a fault in the control circuitry could actuate the valve while work is being done. This keeps the system safe for technicians and aligns with standard lockout/tagout and maintenance safety practices. It’s not limited to commissioning; it’s a common precaution whenever work is performed on the system. After maintenance, the actuator is reinstalled and the circuit reset according to proper procedures.
