EFD90 cable box system Wichmann ® Z-19.15-202. Fire-resistant S90 sealing of cable ducts for foaming in ceilings. The cable box consists 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 that is ready for assembly and is foamed on site with the EasyFoam fire protection assembly foam B1. The assembly foam is a special fire protection assembly foam with high stability and easily controllable expansion behavior. The 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 assembly foam mentioned above. Installation in solid ceilings from 150 mm thick. The cable box can be 100% occupied with cables of all types (without limitation of 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 can be installed without assignment as a reserve bulkhead. When assigning the cables, no gaps are necessary between cables, cables and conduits and between conduits. Within the conduits there is no additional limitation on the cable types and cable diameters. The cable box is also suitable for subsequent installation, as all cable boxes can be opened. In addition, the cable box can be re-assigned at any time while maintaining full functionality. Assembly is carried out in accordance with the enclosed assembly instructions or ABG Z-19.53-2517. No processor validation is required for installation.
