Siamese Twin

Purpose: Installed on the exterior of buildings to allow firefighters to quickly connect hoses and access water from the municipal supply or a hydrant during a fire emergency.

Reason: The Siamese twin configuration allows firefighters to draw water from two sources simultaneously, ensuring adequate flow rates and pressure to effectively combat large fires.

Benefit: Enhances firefighting capability by providing immediate access to additional water, which is crucial in high-rise buildings or large commercial properties where fire water supply needs can exceed the capabilities of a single connection.

Purpose: Used in fire sprinkler systems within large facilities such as shopping malls, warehouses, and industrial plants to ensure reliable water supply.

Reason: A Siamese twin connection allows for greater water flow capacity and redundancy; if one supply source fails, the other can still provide adequate water for fire suppression.

Benefit: Increases system reliability and safety, allowing for sustained water flow during a fire event and reducing the risk of fire damage to property and personnel.

• Purpose: Integrated into the fire protection systems of high-rise buildings to provide adequate water supply for fire sprinkler systems and standpipe systems.
• Reason: Given the height of these structures, the demand for water can be significant. A Siamese twin connection allows for multiple hoses to be connected, enhancing the overall flow capacity and ensuring that firefighters have the necessary resources to fight fires at elevated levels.
• Benefit: Improves safety for both building occupants and firefighters by ensuring that a robust water supply is available, even in emergencies where pressure may drop or sources may fail.
