Vision (Lightweight) Modular Vault Panels

Vision (Lightweight) Modular Vault Panels All VSI panels have been tested by Underwriters Laboratories (U.L.) to meet the standards set under U.L. Safety Standards, U.L. 608. Underwriters Laboratories verifies that these standards are adhered to by periodic inspections of the manufacturing facilities. These standards require retesting for each class, on a seven year basis. This allows U.L. to constantly increase and improve the testing methods to meet the latest technological advances. In addition to meeting the strict security requirements of U.L., the panels have also been tested by United States Testing Company, Inc. This test and evaluation was performed in accordance with the specifications set forth in ASTM Designation E-84. "Standard Method of Test for Surface Burning Characteristics of Building Materials", both as to equipment and test procedure. This test procedure and the apparatus used have been accredited under the National Institute of Standards and Technology/NVLAP Program. The test procedure is comparable to U.L. 723, NFPA No. 255 and UBC No. 42-1. The test summary documents a flame spread of zero and a smoke density of zero. Based on this test, the Flame Spread Classification meets the requirements of a NFPA Class A and a UBC Class 1, both of which require a flame spread in a range of zero through 25. The panels are sized to meet the specific job requirements. The surface of the panel is a smooth galvanized metal. It is recommended that a finish be applied to both sides of the vault by the general contractor. The panel surface lends itself to painting or the direct application of drywall, using "hat channels". The use of a wallpaper liner is recommended prior to the application of wallpaper. The panels are designed to fit together with a minimum of gap not normally found in competitive products. The application of drywall and other wall finishes can save time, money and space. This eliminates the need to provide furring strips which have normally been applied prior to applying the wall finishes. Normal installation requires a smooth and level surface. The use of shims is recommended to correct any imperfections in the floor level. When computing the total square footage of the panels, it is important to note that the outside dimensions are used.

Steel Plate This is used to create a floor for five sided panel vaults. The materials are pre-cut and numbered for installation. Steel plate does not carry any U.L. rating and could compromise the integrity of the vaults. When pricing steel plate for a floor, please provide for panels to sit on the plate.

Support Beams The vault panels have been rated to span the following (inside) distances without requiring additional support. Class M - 16' Class 1 - 21' Class 2 - 29' Class 3 - 36' Access and installation restrictions normally limit the maximum length of panels to 16', regardless of class. To accommodate these restrictions, the standard maximum length of panels is set at 16' and an I-beam is required for spans exceeding 16'. This I-beam is supported by the modular vault walls and the panels are inserted into the beam channel and welded. Please contact engineering if your needs require longer panels.

Support Columns When a vault requires support beams and the length of that beam exceeds 24' a support column is required.

No Column Support This optional method allows for support beams to be of any length. Overall ceiling height is the only restriction, as the size of the I-beam increases. Verify with VSI engineering staff prior to quoting.

Column Wrap Some installations require the vault to be located in an area where an existing building support column is located. It is possible to incorporate the existing column into the vault, however, to maintain security levels, it is recommended that these columns be encased, using vault panels with the same rating as the walls. An alternative is to wrap the column in steel plate welded together and to the vault ceiling and floor. Steel plate does not carry any U.L. rating and could compromise the integrity of the vaults.

Installations Supply Package This package included three sizes of shims, appropriate anchors and caulking. In the event VSI performs the installation, these items are included in the installation charge.

Vent Ports All VSI vent ports have been tested by U.L. to meet the standards set under Standard for Safety U.L. 680. U.L. verifies that these standards are adhered to by periodic inspections of the manufacturing facilities. The vent ports are incorporated into a special panel to facilitate the Heating/Air Conditioning Contractor. Vent Ports can be sized for airflow from 4" x 16" to 4" x 36". This adjustability should result in cost savings through the reduction in the use of ductwork. Provision is made to allow for the attachment of HVAC vents without jeopardizing the vault security.

Angle Iron Angle iron is required on all five sided vaults. The angle is secured to the vault floor and the panels are secured to it. Angle Iron may be eliminated if the contractor embeds steel in the slab to allow the panels to be anchored.

Conduit Access Each vault is equipped with six conduit connections for the electrical and alarm contractor. Additional conduit connections are available. These are installed in accordance with U.L. specifications.

Sprinkler Access When required by local code, sprinkler access may be provided. In accordance with U.L. specifications, these are limited to 1 1/4" ID and 1 1/2" OD.
