Sound and smoke protection attachment for rectangular cable boxes System Wichmann ®. The flexible silencer for cable boxes for overhead cabling. If particularly high sound protection requirements are placed on fire barriers and the barriers should also be able to be retrofitted quickly and without causing any damage, the sound and smoke protection attachment (SRV) is used: Similar to the acoustic box in version E, the SRV is screwed to the wall or ceiling opening. The well-known cable box System Wichmann ® seals off the penetration safely in S90 quality and the SRV provides sound protection and cold smoke protection. The lid is simply opened using the tension lock and the cables are placed between the foam layers. The advantage is that the corrugated surface of the foam layers in the SRV is designed in such a way that it can enclose the cables without creating gussets on the sides. In this way, both cold smoke sealing and airborne sound insulation are achieved without having to use sealants such as silicone. The SRV is therefore particularly suitable for flight cabling, e.g. in studios or laboratories, where cables must be removed after use and must not be glued together. The SRV has been tested for fire protection and sound. Installation is carried out in accordance with the enclosed installation instructions. No processor validation is required for installation.
