Knox Information


All automatic gates across fire access roadways, which include driveways, need to be equipped with an approved emergency key-operated switch overriding all command functions and opening the gate. All automatic gates must meet fire department policies deemed necessary by the Chief for rapid, reliable access. Automatic gates serving more than one dwelling are required to install an approved KNOX® emergency Our key-operated switch, or other mechanism approved by the Chief, at an approved location, which overrides all command functions and opens the gate(s).

Automatic gates serving more than four dwellings or residential lots are required to install emergency traffic control-activating strobe light sensor(s), or other devices approved by the Chief, which will activate the gate on the approach of emergency apparatus with a battery back-up or manual mechanical disconnect in case of power failure.

All central station-monitored fire detection systems and fire sprinkler systems shall have an approved emergency key access box on site in an approved location. The owner or occupant shall provide and maintain current keys for the structure(s) for fire department placement in the box, and the owner must notify the fire department when the building is re-keyed.
