With one master key, The City of Martin Fire Department can gain access to commercial and residential property. More than 11,500 departments in North America use Knox® products. The Knox System includes UL listed lock boxes, storage cabinets, heavy-duty padlocks and electronic override key switches. The system has grown to include locking FDC plugs and caps providing protection to the intake and discharge sides of water-based fire protection systems.

The City of Martin Fire Department uses the KeySecure®, master key security system, to control the Knox Master Key. These Master Key Retention units provide accountability with an audit trail giving the date, time and user ID for each key release.

Property owners in the City of Martin store entrance keys or access cards in Knox-Box® key boxes mounted near their building entrances. Each Knox-Box purchased by the property owner is keyed to a single master key controlled by The City of Martin Fire Department. With the Knox System, there is no cost to the fire department, no waiting for a property owner to unlock the door in the middle of the night, and no forcing the door open to gain entry. The Knox Rapid Entry System reduces response time, property damage and the liability for lost keys.

The City of Martin enacted an ordinance that requires the KNOX® System for all commercial, industrial, and assembly occupancies that have automatic fire alarm systems and/or automatic fire suppression systems.  Click Knox Box Ordinance to view the Ordinance.
