FDC stands for Fire Department Connection. It is the inlet where firefighters connect their hose lines to add water from their fire trucks to the building’s fire suppression system. A sign is needed because it tells firefighters where to find this connection. This information is vital when they arrive at a scene and must increase water pressure quickly to control a fire.

On the exterior of buildings, usually near the main entrance or along the street-facing facade where fire apparatus can pull up. The location is typically established during building design in coordination with the local fire department. FDC signs go directly on or adjacent to the connection itself.

Yes, fire codes do require FDC signs. NFPA 13 and NFPA 14 both say that FDC locations must be clearly marked. The International Fire Code (IFC) also says the connection must be visible and easy to reach. Local fire codes and the Authority Having Jurisdiction may have rules. It is always good to check with your fire marshal to be sure you meet all requirements.

The sign should show "FDC" or "Fire Department Connection." It should also say what system the connection supplies, like "Sprinkler," "Standpipe," or "Combined." For larger or more complex buildings with multiple systems, indicating which system the connection serves helps firefighters work faster.

Yes, the sign needs to be visible from the street. The purpose of the sign is to let emergency vehicles find the connection fast. If the connection isn’t in sight from the street or usual access point, then directional signs pointing toward it are also needed.

Yes, FDC signs are made to last. They use weather-resistant materials like waterproof vinyl. These signs can handle sunlight, rain, freezing temperatures, and heat without fading or falling off. The adhesive holds strong over time when exposed to the elements.
