The Master SOPV's action includes which of the following?

• A. Activates the siren
• B. Turns the pump on
• C. Opens the cooling circuit
• D. Closes the discharge path

Answer: (B)

The main idea being tested is what the Master SOPV does in the foam transfer sequence. The Master solenoid-operated valve is the control that starts the transfer pump. When it is energized, it powers up and runs the pump, pushing foam concentrate through the lines to the discharge. It’s not responsible for sounding alarms, opening a cooling circuit, or closing the discharge path. Those systems are separate: alarms are handled by the alarm system, cooling circuits are part of the plant’s cooling system, and the discharge path is controlled by other valves or interlocks. So the Master SOPV’s action is to turn the pump on.
