I want to give you this opportunity to kind of understand what the system does when it senses a fire in the room. We're going to discharge gas out through the ceiling, and before the gas goes off. We'll hear a little beeping in the background, and then the pre-discharge warning signal that's warning the people and the occupants of the room there's going to discharge. Then the gas will come out of nozzles in the ceiling, and the vision in the room will be obscured at that point. We call that fogging due to the agent expanding in the room. That fogging stops pretty quickly after the system stops discharging, and it returns back to normal vision inside of the room. A couple of other things that we'll notice is while those nozzles are going off, it's pretty loud. Then here finally we'd also see this a piece of paper taped to the front of that cabinet. It will be flopping around because we'll know that now the discharge is turbulent because of the gas escaping from the nozzles. Back in the day with Halon systems, we used to discharge test those all the time. Today we use other operational tests to make sure that the system will work, but we don't discharge test systems. We just happen to have this video of a discharge test happening so it's useful for teaching about clean agent systems.
