Questions & Answers

What is a Knox-Box System?
It’s a high-security key box system, designed to give firefighters immediate access to locked buildings, elevators, and other secured areas.
How does the Knox-Box System work?
Following your purchase of a Knox-Box from the factory, you will mount it securely on the exterior of you building (attractive recessed-mount models are available). All necessary access keys will be locked inside by a representative of the fire department (only the fire department’s master key can open this box).

The Knox-Box gives the fire department a simple alternative to expensive, time-consuming forcible entry. The generous interior capacity allows you to store everything emergency personnel may require – keys, floor plans, electronic entry cards, emergency contact names and numbers, and more – in complete security until needed.
Why install a Knox-Box System?

Installation of a Knox-Box on your property will not only allow firefighters faster access in case of an emergency, but will also prevent expensive forcible entry should emergency services be required while the premises are unoccupied. Costly front doors and entry ways needn’t be harmed if entry keys are available on-site.  After an incident the front doors can simply be locked again securing your building and contents.

How is a Knox-Box System installed?

Each Knox-Box is shipped with complete mounting instructions; however, Camdenton Fire Prevention Bureau will assist you in choosing a proper location for mounting. All Knox-Boxes shall be mounted 72-84 inches from the ground to the center of the box and within 10 feet of the primary entrance. After installation is completed, contact the Fire Prevention Bureau at 573-346-6260 to conduct an inspection of the installation and secure the required information inside the box. Once completed it is ready to provide immediate access to emergency personnel 24 hours a day, 365 days a year.

How secure is a Knox-Box System?
Security has always been a Knox strong point. Designed for maximum protection, each virtually indestructible box (UL 1037) features a special high-security Medeco lock and key. This Medeco restricted locking system guards against unauthorized key duplication. Keys aren’t even available to locksmiths or lock distributors – only The Knox Company can supply these keys!

Our system offers maximum security at every step. Each city has an exclusive key code. All Knox-Box stations in that city are keyed alike – and only the Fire Department has master keys. Master keys are secured on our apparatus and are released via 911 emergency dispatch for the utmost in accountability and tracking purposes.  The Fire Marshal's vehicle is the only vehicle that can release the Master key by entering a code.  The tracking and accountability is the same.
Who can authorize a Knox-Box System? / Ordering Information
