Siamese signs – The signs are designed to inform 1st respondends about Siamese connection location and type of connection. The Fire Department Connection, also commonly known as the Siamese connection, is an important component found on most sprinkler and standpipe systems. When a fire sprinkler system activates, the FDC provides a means for firefighters to connect hose lines to supplement the fire sprinkler system's domestic water supply. We can say it is called two for one. In case one side of the Siamese does not work, the other one will support it.

Frequently asked questions about Siamese signage and how the Siamese work:

How does a Siamese fire connection work? A siamese connection or splitter in fire protection engineering is a pipe fitting that allows two or more fire hoses to be connected to a single standpipe riser at the same general location. It is called so due to the visual similarity to siamese twins

What is the purpose of Siamese connections? The Fire Department Connection, also commonly known as the Siamese connection, is an important component found on most sprinkler and standpipe systems.

Siamese connections is a fire department connection. One can find a fire department connection in many high rise building and new constructions. Those are pipes in front of buildings painted red, green, and yellow and look like fire hydrants. They are used by the fire department crew to fight fires.

Why it is called “Siamese”? They are called so, because of their visual similarity to Siamese twins since they encompass two pipe openings for a single pipe that leads either to the building’s standpipe, a vertical water pipe that leads all the way to the top of the building, or the building’s sprinkler system, or both. One opening is a backup for the other, in case the first is defective, though it can also be connected to a second hose if more pressure is needed.
