What is a fire department connection (FDC)?

A fire department connection (FDC) serves as a critical point within a fire protection system, specifically designed to allow firefighters to quickly and efficiently access a building's water supply. This connection typically consists of a series of ports or valves that enable fire hoses to be connected directly to the fire suppression system, such as a standpipe or sprinkler system. By utilizing the FDC, firefighters can supplement the building's existing water supply, ensuring an adequate flow of water during firefighting operations.

This design is vital for enhancing the effectiveness and speed of fire response efforts, as it eliminates delays associated with locating alternative water sources at the scene. Essentially, the FDC acts as a bridge between external fire apparatus and the building's internal firefighting capabilities, improving both safety and efficiency during emergencies.
