Installers and contractors need the latest edition of NFPA 13R, Standard for the Installation of Sprinkler Systems in Low-Rise Residential Occupancies, to complete jobs correctly, work with the latest technologies, and reduce risks while maximizing efficiency. The updated edition of this standard includes comprehensive requirements governing system installation, including the water supply and system acceptance. In 1989, the first edition of this standard was published and was a landmark for the creation of sprinkler installation design standards. NFPA 13R was created to provide people residing in low-rise multifamily dwellings with a high degree of life safety and property security. By staying up to date with the latest requirements in this standard, installers and contractors can help ensure the safe and correct installation of sprinkler systems for people living in low-rise residential occupancies.
