Basics Fixing of sprinkler systems. Sprinkler systems are designed and installed to different standards. For example, to the German VdS standard (VdS CEA 4001), to the American FM standard 1951 (Factory Mutual Insurance Company, FM Global), to the UL (Underwriters Laboratories, UL) based on the NFPA 13 standard (National Fire Protection Association, NFPA) or to the European standard EN 12845. The European guideline CEA 4001 was introduced in 1995 by the insurance industry in collaboration with the manufacturers’ association and in Germany in 2003 by “VdS Schadensverhütung GmbH” as VdS CEA 4001. EN 12845 was created on the basis of the CEA 4001 of 1995 and the VdS CEA 4001 of 2003, so that the resulting standard is virtually the same. The EN 12845 is supplemented by the EN 12259 series of standards for the most important components but does not cover the further requirements of fixing products. 12 The American standards correspond with each other and with the European standards and guidelines regarding the fixing of pipework. The differences are in the detail and must be noted in the respective use.
