The key lock box shall be compatible with the master key assigned to the Fire Division. The master key is assigned only to the Auburn Fire Division. The key lock box shall be located at or near the recognized main entrance. The key lock box location shall be approved by the Inspection Services Department prior to installation.

Full Breakdown

1, Locks, to require every occupancy in the city with an automatic fire alarm system or fire sprinkler system to install an Underwriters Laboratory-listed key lock box compatible with the master key assigned exclusively to the Auburn Fire Division. The Inspection Services Department must approve the lock box's exact location before installation, and the box must be mounted no lower than 6 feet and no higher than 7 feet above final grade, near the recognized main entrance, with nothing such as steps, signage or other fixtures placed beneath it that would let an intruder reach it without help.

The building owner or manager installs the box where Inspection Services directs and must notify the division once installation is complete. Where a fire alarm control panel is present, the box connects to it and is wired so that tampering or opening the box produces a supervisory signal on Supervisory Zone 1, transmitted through the NFPA 71 panel; buildings using an NFPA 71 panel alone follow the same tamper-signal rule. The box must contain labeled keys to the main entrance, any alarm room, mechanical rooms, sprinkler control and fire pump rooms, the fire alarm control panel, electrical rooms, special keys for pull-stations or other fire protection devices, elevator and elevator room keys, and any other room the fire plans reviewer specifies. The only exception is a building or site staffed with 24-hour, seven-day guard service, which does not need a lock box at all.

Violations & Fines

Failing to install or maintain the required Knox box on a qualifying occupancy violates the adopted Fire Code under Auburn Code § 5-5, a misdemeanor under § 1-9 punishable by a fine of up to $500 and/or up to six months in jail. The Auburn Fire Division can also withhold final fire inspection approval until a compliant lock box is installed and stocked with the required keys.

Frequently Asked Questions

Where does the Knox box have to be mounted?
It must sit at or near the recognized main entrance, between 6 and 7 feet above final grade, with no steps, signs or other obstructions beneath it that would let someone reach it without assistance. Auburn's Inspection Services Department must approve the exact location before installation.
What keys go inside the lock box?
