Each system from the Knox Company is shipped with complete mounting instructions; however, the Prevention and Life Safety Division can assist you in choosing the proper location for mounting. The Knox Box should be mounted no more than 6 feet and no less than 4 feet. Once installation is complete, contact the Fire Marshal's Office to conduct an inspection and secure the Knox Box. Once that is completed, the Knox Box is ready to provide immediate access to emergency personnel 24 hours a day, 365 a year.
