Fire Sprinkler Signs- The signs are designed to identify different controls and pipes for fire sprinkler systems in your facility. A fire sprinkler or sprinkler head is the component of a fire sprinkler system that discharges water when the effects of a fire have been detected. Many states require owners to install clear signs identifying the different types of fire sprinklers used.

There are various types of fire systems. 4 of them are described below:

Dry Pipe Sprinkler system-Dry pipe sprinklers are similar to pre-action systems as they use pressurized air in the pipe which exits before water escapes. This causes a minute delay in water discharge but is ideal for buildings with low temperatures so the pipes do not freeze. These fire sprinkler systems have a fast opening tool to get rid of the air and speed up the flow of water. Warehouses located in the north are a good example of what buildings should use dry pipe sprinklers.

Wet Pipe Sprinkler system-Wet pipe fire sprinklers constantly have water in them. This allows for a quick reaction to a fire and is the most common type of sprinkler installed in buildings. A type of building that uses the wet pipe system is a high-rise or office building with a few floors. This fire sprinkler system is cost efficient and low maintenance.

Pre-action fire sprinkler system-Pre-action fire sprinkler systems are filled with air and water is allowed to pass through when the smoke alarm or detector goes off. This type of system requires two triggers to start water flow. It helps greatly that the pre-action fire sprinkler can be set to prevent water from spouting in case of a false alarm or a mechanical failure. The pre-action system is good for use in places where the sprinklers are only necessary when there is an actual fire so other items in the building do not get water damage from an accidental sprinkling. Such buildings include libraries and data centers. These places contain items of high value like electronics and goods damageable by water such as books

Deluge Fire Sprinkler -These types of fire sprinkler systems also need a smoke or heat detector like the pre-action system. A deluge system has open nozzles that can be used when a hazard is present. When flammable liquids are spread across a floor, deluge fire sprinklers are good to have. In that case, buildings such as industrial parks and buildings with many tanks have deluge fire sprinkler systems installed.

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. 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

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.
