[BLANK_AUDIO] [MUSIC] Welcome to Fire Engineering's Training Minutes. My name is Paul Dansbach. In today's session, we're going to show examples of floor control valves. Floor control valves that control the flow or supply of sprinkle water to a given floor in a multi-story building. What we have behind us is our sprinkler riser. As we would have in most buildings, we have our sprinkler riser with our class one stand pipe valve located on the riser. You will notice as the riser continues up vertically, it T's off to an OS and Y valve. That OS and Y value is the floor control valve that controls the flow of water to the sprinklers on the 9th floor of this building. In the event of a fire on the 9th floor. When it comes to the point during the incident where the sprinklers need to be shut down, firefighters should go to the floor control valve and shut down the sprinkler valve. By closing the floor control valve, the stamp pipe outlet will still be charged. If it were necessary to shut a valve on a lower floor or the main control valve to this system, it would shut off the standpipe outlet. And the fire department would have no water supply to continue overhaul of the fire. Floor control valves are required. Any time a combination sprinkler stand pipe riser is utilized, the floor control valve allows the fire service to shut the water supply to sprinklers. Where the fire occurred and keep the stand pipe outlet charged. It also helps reduce the amount of building that is shut down in the event of a fire or other impairment that requires a sprinkler on a given floor to be shut down. We're now looking at another sprinkler stamp pipe riser. Here's the riser. Here's our class one stamp pipe outlier. As we continue up the pipe, the pipe T's off to a butterfly control valve. That butterfly control valve is the floor control valve for the automatic sprinkler system for that floor. We continue down the pipe, we come to a series of valves. During a fire in this building when there came time to shut the automatic sprinkler protection down. And any, and they shut down any automatic sprinkler protection has to be closely coordinated with the operations officer and the incident commander. After shutting down the butterfly control valve, the firefighter would open up the drain valve to drain the residual water out of the automatic sprinkler system.
