Knox Box Program

The Knox Box Program provides the San Diego Fire-Rescue Department with a quick and easy means to access a secured building or area during an emergency. It also minimizes potential costly repairs caused by forcible entry and allows the building to be re-secured quickly and easily. When access is difficult for emergency responders, the Chief is authorized to require a Knox Box or Key Switch to be installed in an acceptable location. (CFC 2019 Section 506)

Knox FDC Locking Caps

Fire Department Connections (FDCs) play a critical role in ensuring the safety of a building by allowing the fire department to provide or supplement water pressure to fire protection systems. FDCs are provided with a cap or plug to protect the threads and maintain the integrity of the fire protection system that it supplies. These protective caps are often missing which allows for trash and debris to accumulate inside the FDC, making the system unreliable for use. A compromised FDC can cause a loss in water pressure or complete system failure which puts firefighters and the public at risk.

The Knox Company provides a Knox FDC Locking Cap which is designed to be installed and removed with a specially designed key wrench. Knox FDC Locking Caps can be ordered by anyone, but keys are only obtained by sprinkler contractors and San Diego Fire-Rescue personnel. These caps are required for all new buildings with FDCs and existing buildings, as deemed necessary by San Diego Fire-Rescue personnel.

Procedure for ordering Knox FDC Locking Caps:

Knox FDC Locking Caps are the only Knox product ordered directly through the Knox Company. For ordering please contact the Knox Company at 800-552-5669 or

Refer any questions to the Knox Program Coordinator.
