I don't know the Falcon 50 but on my aircraft, pulling the fire handle not only shut down the engine by closing the fuel valve, it also closes the hydraulic valve, the bleed valves, shuts off the generators and arms the fire bottle squids.
If you then proceed to turn the fire handle the fire extinguishing agent is then released in that engine.
