Knox Box / Key Box

Knox Life Safety System


Marietta utilizes the Knox Life Safety System as our designated method of emergency access for real property and buildings.  A Knox box is required for all buildings and/or tenants protected with a fire alarm or fire sprinkler system.  A Knox Box must be mounted at 5’0” above grade at/adjacent to the main entry.  Powered gates shall provide a Knox key-switch, located at the common call box.  Our department does participate in the FDC protection program.  Locking FDC caps and/or standpipe caps are required on new building projects over $1M.  Please use caution when ordering from the KnoxBox website - Georgia - Marietta Fire Department is the only acceptable selection.  If the Knoxbox product is not keyed to the Georgia - Marietta Fire Department, the device will be required to be replaced with one that is properly keyed.
