Fire approved fixings

Law regulations may vary by country. Please contact CELO experts to provide you with further information on approvals and local requirements. Our experts in structural fire protection in electrical installation technology will assist you. Fire safety in buildings generally requires that in the event of a fire sufficient time is available for people to escape from a building: certain walls, floors and fasteners provide fire resistance for the purposes of constructing fire compartments and/or protected escape routes ensuring the structure doesn't collapse. For system fastenings, the approvals of the cable systems with integrated maintenance of electrical functionality according to DIN 4102 Part 12 require metal anchors with a general construction approval or a European Technical Approval/Evaluation. In contrast to normal "cold" fastening, these anchors must be set at least twice as deep for a fire protection application. Alternatively, anchors are used which have proven their load capacity and fire resistance length in a fire test. With these solutions, the necessary setting depths according to the load are listed in the approval documents or in the appropriate fire protection reports. It must also be noted for which substrates and resistance classes the anchors are approved.
