Firelock Fireproof Modular Vault Chamber Components


All Firelock fireproof modular vault chamber components have been tested and certified to be rated at least Class 125 Two Hour. This means the temperature inside the vault will remain below 125°F for at least a two hour period, even if temperatures outside the vault reach 2,000°F.



The following is a list of Vaulting Components.

Patented modular panel system

The wall and roof panels utilize ceramic fiber, a high-temperature industrial insulating material, as the key to stopping heat migration in a catastrophic fire.

The inside face of all panels have a steel vapor barrier to ensure steam (from water sprinkler discharge or fire-fighting efforts) does not enter the vault chamber. All vaults are custom designed to meet the exact size requirements of each client.

Firelock-double-door-assemblyDouble door assembly

There is no single door that will achieve the stringent Class 125 rating, so a combination of fire-rated doors is employed to reach this level of protection for computer server rooms.

Automatic door closers

Firelock-automatic-door-closersIt is very possible that no one will be in the data center when the building is evacuated. To ensure the vault is sealed when fire strikes, an automatic door closer is installed on both doors. The door closers are activated when their internal sensors detect:

  • Heat
  • Smoke
  • Flammable gas
  • Power failure


Insulated self-sealing cable penetrations

This is an area that must be sealed when exposed to heat. Firelock modular server vaulting is equipped with ceramic fiber insulated assemblies with PVC conduit and heat-reactive expanding caulking. This is the same type of self-sealing conduit penetration that is used in nuclear power plants to safeguard critical areas.

Insulated self-closing damper assemblies for air duct entry points

A three stage insulated damper assembly is used to prevent heat migration through air duct entry points. These insulated dampers can be located wherever they’re needed for providing fresh make up air or removing warm air from heat-generating servers, to help keep the server room temperature in the optimum range.

Firelock-insulated-self-sealing-coolant-line-penetrationsInsulated self-sealing coolant line penetrations

If a split HVAC system is used in the data center, such as a Liebert unit, an insulated conduit penetration is used to protect the vulnerable area where the coolant lines enter the vault chamber.

Firelock-uni-strut-track-cable-managementUni-strut track for mounting cable management systems

By welding Uni-strut directly to the roof panels inside the Firelock vault, server vaults can be outfitted with neat and efficient overhead cable management systems. This eliminates the need for costly raised floor systems and protects cables from the threat of water exposure in a flood.

Firelock Fireproof Modular Vault Chambers

Firelock-logoFirelock™ is the world’s leading manufacturer of media-rated modular vault chambers. Unlike poured-in-place concrete vaults, Firelock vaults are constructed from individual panels, filled with a heat-resistant ceramic material and are lightweight, movable, and expandable. When combined with current high density storage systems, Firelock vaults offer extremely high space efficiency and a considerable cost advantage per cubic foot of storage.

The value of assets stored in Firelock vaults today reaches hundreds of billions of dollars and ranges from priceless animation cells and World Wrestling Entertainment videos to pharmaceutical research records and U.S. Department of Education student loan information.

With a Firelock server vault, you invest in the highest performing vault on the market today to ensure the protection of your most vital records and irreplaceable items. You gain the ability to store microfilm, computer media, file servers and paper in one location, and the peace of mind that comes from knowing that all the environmental and fire protection elements are in place.

Firelock Modular Vault Chamber Server Vault Components

Firelock has been in business for over two decades, and during that time has installed over 1,200 vaults around the world. In the United States there are vaults in 44 of the 50 states, as well as Europe, the United Kingdom, Scandinavia, South America, Africa, Korea, China, Taiwan and Hong Kong. Because of this broad experience, Firelock knows how to build a vault that will provide our clients with maximum protection today and have the flexibility to grow with them over time.

Features & Benefits

Modular construction Built from panels that are 24 inches wide and can vary in height from eight to 20 feet, vaults are custom-designed to meet current needs and can expand as those needs change.

Lightweight, modular vaults allow for maximum storage flexibility without exceeding floor load requirements in high rise office buildings.

High temperature protection
  • Vault panels constructed from spun ceramic material capable of withstanding temperatures well above 2000°F for five hours of testing.
  • UL Class 125 vault door assembly is made up of both an outer vault door and an inner door. The thermal break between doors enhances data protection by increasing the barriers to migrating heat.
  • Metal conduits can carry heat into the vault. We solve this problem with a specially designed cable tray.
Solid framework Unique structural steel design that offers 3 times the strength of a normal building construction.
Magnetic shielding and roof protection Magnetic shielding components protect against the most common electromagnetic fields that can damage media stored archivally in one location. Firelock’s Roof Deck protects the vault when sprinklers activate or during fire fighting process.
Essential environmental planning and design Firelock vaults are pre-designed to integrate dust and vapor resistant lighting, humidity control, and fire suppression systems which are not harmful to the environment and do not add to global warming.

Proper environmental control is critical for sensitive microfilm and magnetic media. Our AC Duct/Damper assembly provides air circulation without violating the integrity of the vault.

Flexible design Light enough to install on an upper floor and adaptable enough to move to a new location.
Multi-level options The lightweight nature of the Firelock vault allows for the construction of multi-level units, providing higher density storage and maximizing profit per square foot of warehouse space.
