WRONG! Pulling the T-handle does NOT provide power to discharge the fire bottles. Pulling the T-handle does nothing more than actuate the valves on the system to direct the agent to the appropriate engine. It also cuts fuel, bleed air, oil pumps, feathers the prop, etc. as stated above. However, at ANY TIME you can press the agent discharge switch to the 1 or 2 position and the agent will discharge BY DEFAULT to the #2 engine at anytime, provided no T-handles are pulled. If any of the T-handles are pulled, it will discharge to that particular engine or the APU based on valve positions.
