Southern Marin Protection District uses the Knox Entry System to allow secure access to businesses and residences by the Fire Department during an emergency.

A Knox Key Box is a secure box that is mounted externally to a commercial building that contains access keys in the event of an emergency.

A key box is required where:

• access to building is difficult
• in buildings with fire alarm or sprinkler systems
• all facilities that are required to submit a hazardous materials business plan
• where electronic and manual gates could hamper emergency access

The Knox Key Box models that are approved by the Mill Valley Fire Department are:

• 3200 series - Standard Box
• 4400 series - Heavy Duty/Vault
• 3500 series - Key Switches for gates
• Padlocks - for gates

All Knox Box purchases can be made online.
