Knox box

A Knox Box is required on all new construction and existing construction undergoing substantive remodel. When access to a building or area is necessary for life-saving or fire-fighting purposes or for access to fire protection equipment, a Knox Box will be required as designated by the Fire Marshal.

All occupancies that have a fire sprinklers system, fire alarm system, special hazards, hazardous materials or high piled storage are required to have a Knox Box. The size of the key box shall be determined by the type of occupancy and hazards present.

Buildings defined as a high rise require a Knox Elevator/Lobby Box in the Fire Command Room.

A Knox box shall be located adjacent the main entrance and at the Riser Room installed at a height of 6 ft. above grade. Additional key boxes may be required based upon access, location of fire protection systems and occupancy use and size.

A Knox Padlock, Model 3770, is required on all manual and automatic access controlled gates, pedestrian and vehicle, when the gates obstruct the fire lane and/or access to a building. In addition, a Knox Key Switch/KS-2, Model 3502, is required for all automatic access gates.
