The purpose of this procedure is to clearly define the requirements for commercial building key boxes including; approve key box types, key box ordering, key box installation, securing of key boxes and updating of existing key boxes.
The International Fire Code (IFC), as amended by Boise City Ordinance, requires key boxes for all structures with fire alarm or fire sprinkler systems which are connected to a monitoring service. The required key box for the Boise City Fire Department (BFD), Whitney Fire Protection District (WFP) and North Ada County Fire & Rescue District (NACFR) is the KNOX-BOX manufactured by the KNOX Company.
Boise City Fire Department allows the 3200 Series with hinged doors and the 4400 Series KnoxBox. The 3200 Series holds ten keys, or usually 1 to 2 sets, and is usually adequate for small buildings. In large, multi-story or multi-tenant buildings the 4400 Series, which holds up to 50 keys, will be required.
Key Boxes can be ordered either online.
