Abstract
A method of checking a pressure of an agent cylinder that includes coupling a gauge assembly to an outlet of a gauge tool, the gauge assembly having a pressure gauge and a vent valve movable between an open position and a closed position. The method further includes moving the vent valve towards the closed position; attaching a fill adapter defining an inlet of the gauge tool to a valve port of an agent cylinder; and actuating a drive member of the gauge tool in a first direction to move a valve member of the gauge tool from a first position towards a second position to facilitate a fluid flow between the inlet and the outlet of the gauge tool.
