How far should you pull the Carbon Dioxide system control head cable handle?

Explanation:
The correct answer hinges on the release mechanism’s required travel. The CO2 system control head cable is designed to activate with a specific stroke, about 3 to 5 inches. This range ensures you move the handle enough to fully trip the valve and discharge CO2, but not so far that you risk mechanical damage or accidental misactivation from over-pulling. In practice, grab the handle and pull smoothly through a 3–5 inch movement to reliably activate the system, then proceed with the established safety and firefighting procedures.
