Guide to FDC Locking Caps and Fire Department Connection Protection

Fire Department Connections (FDCs) provide access to a building’s fire sprinkler system when firefighters need to supplement the available water supply during a fire. Because FDCs are exposed to the elements and accessible from outside a building, they can be vulnerable to debris, vandalism, and damage.

FDC locking caps provide a way to secure the connection while helping protect it from these issues. The Knox FDC Lock helps secure and protect Fire Department Connections from these issues.

How FDC Locking Caps Help Protect Fire Department Connections

FDC locking caps secure the opening of the Fire Department Connection and help prevent unwanted access.

The Knox FDC Lock uses a locking mechanism operated with a Knox Keywrench controlled by the fire department. This allows the FDC to remain secured while providing authorized fire department personnel with access when needed.

The Knox FDC Lock is designed to help protect FDCs from:

• Debris that can enter the connection
• Vandalism that can damage or compromise the FDC
• Damage to the connection and its components

The Knox FDC Lock is also designed to help protect check valves from freezing in cold climates. By helping keep debris out of the connection, it can also help reduce the need for costly back-flushing services caused by debris.

For additional protection, the Knox FDC Lock is available with an Anti-Theft Guard option, providing added protection for the FDC swivel.

What to Consider When Choosing an FDC Locking Cap

The right locking cap needs to match the Fire Department Connection it is intended to protect. Size is an important consideration when selecting an FDC locking cap, as the cap needs to match the existing FDC connection.

Construction is another consideration. The Knox FDC Lock features stainless steel construction designed to withstand outdoor weather conditions.

The locking method is also important. Because the Knox FDC Lock is operated using a Knox FDC Keywrench controlled by the fire department, the FDC can remain secured while still being accessible to authorized personnel.

Are FDC Locking Caps Required?

Whether an FDC locking cap is required or appropriate can depend on the applicable requirements for the property and local fire authority.

Because requirements can vary, it is important to confirm the applicable requirements with the local Fire or Public Safety Department before selecting an FDC locking cap.
