Additional element for UFK cable box system Wichmann ® Z-19.15-202. Fire-resistant S90 sealing of cable ducts in the system floor area, in the screed floor or under doors. The two-sided UFK extension element may only be installed in conjunction with a three-sided UFK cable box. The UFK cable box and the matching UFK extension element consist of a galvanized sheet steel housing, lined with fire protection agent that foams up in the event of a fire. The fire sealing is functionally separate from the cold smoke seal and works independently of the seal. The functionality of the cable box is not interrupted by subsequent installation work. The cable sealing is delivered as an industrially prefabricated and functional component ready for assembly and is mortared or plastered in on site. Incorrect and over-installation are almost impossible due to the design. The UFK cable box can be attached directly to the subfloor over cables that have already been laid because its underside is open. In the area where the UFK boxes are used, it is not always possible to install several cable boxes next to each other due to the structurally limited installation heights of the system floors in conjunction with enormous amounts of cable. But that's not a problem: the UFK cable box with add-on part simply expands in width and can thus double its clear width. The included EasyFoam foam plugs are used for cold smoke sealing. They have a much lower density and are therefore easier and quicker to process than, for example, fire protection plugs. The cables and the housing are sealed with a permanently elastic sealant (e.g. silicone or acrylic) or with the EasyFoam fire protection assembly foam B1. Installation in the system floor area and in light partition walls or in solid walls from 100 mm thick. The cable box can be 100% filled with cables of all types (without limiting the cable diameter) and with electrical installation conduits in accordance with DIN EN 61386 with and without cable assignment up to a diameter of 63 mm. In addition, the sealed cable box with add-on element can be installed without assignment as a reserve bulkhead. When using the cable, no gaps are required between cables, cables and conduits and between conduits. There are no additional restrictions on cable types and cable diameters within the conduits. The UFK cable box with add-on element is particularly popular as a bulkhead under fire doors near inspection openings in the system floor, as it can be retrofitted at any time without much effort and without causing any damage. Installation is carried out in accordance with the enclosed installation instructions or ABG Z-19.53-2517. No processor validation is required for installation.
