In a fixed carbon dioxide extinguishing system for a machinery space, designed WITH a stop valve in the line leading to the protected space, the flow of CO2 is established by actuating _______________.
AI Explanation
The correct answer is A) two controls.
In a fixed carbon dioxide extinguishing system for a machinery space that is designed with a stop valve in the line leading to the protected space, the flow of CO2 is established by actuating two controls. Specifically, the system requires the actuation of both the release control and the stop valve control in order to discharge the CO2 into the protected space.
The other options are incorrect because: B) three controls are not required, C) one control is not sufficient to establish the flow of CO2, and D) none of the above is not the correct answer since the system does require the actuation of two controls.
