It's very simple, you hook up a vacuum pump to the inspector's test connection and draw the air out. Then open the valve (good luck with that one) and allow the water to be sucked into the system.
Sort of goes along with the idea of hooking up the vacuum pump to the sprinkler system and when the sprinkler goes off, suck all the air out of the room and extinguish the fire that way.
