AIR PRESSURIZED DRY STANDPIPE SIGN
Our standpipe signs – Design to inform 1st responded about the standpipe system in the building and their locations. A Standpipe system is a series of pipes which connect a water supply to hose connections, basically an extension of the fire hydrant system. They are designed to provide a pre-piped water system for building occupants or the fire department.
A standpipe system is An arrangement of piping, valves hose connections and other equipment installed in a building or structure, with the hose connections located in such a manner that water can be discharged in streams through attached hose and nozzles, for the purposes of extinguishing a fire, thereby protecting a building or structure and its contents in addition to protecting the occupants. This is accomplished by means of connections to water supply systems or by means of pump tanks and other equipment necessary to provide an adequate supply of water to the hose connections.”
It is, essentially, a way of delivering water from one area of the structure or facility to another so that we can fight the fire while at the same time shortening the length of the supply and attack lines. Standpipes can be an intricate or simple system, but the result is the same: water delivery. These systems can be vertical (which is the common type) or they can be horizontal.
Below are four types of standpipes that you will find in use:
- Wet system. Here, water is in the pipes at all times and is supplied by a water source. The pressure in the system is constantly maintained.
- Automatic dry standpipe. Here, there is always air stored inside the standpipe at a constant pressure. When a hose valve is opened, the air escapes allowing the water to enter into the standpipe system.
- Semi-automatic dry standpipe. In this system, air is stored inside the pipes, which can be pressurized or not be pressurized. Once an actuation device such as a manual pull station or an electrical switch is activated, water then enters the system.
- Manual dry standpipe. This type of system has only pipes feeding the system with no air or water in them. A fire apparatus must be used to supply the water through the standpipe.
