NFPA 13R helps you design and install life-saving sprinkler systems in multiple-family dwellings -- to safeguard people and property from fire. For effective and economical sprinkler system installation in multifamily occupancies -- such as apartment buildings and hotels -- buildings, designers, owners, and AHJs rely on NFPA 13R: Standard for the Installation of Sprinkler Systems in Low-Rise Residential Occupancies.
The 2013 edition of NFPA 13R: Standard for the Installation of Sprinkler Systems in Low-Rise Residential Occupancies introduces a new title along with major updates reflecting industry developments. Changes include a four-head calc that will help eliminate conflicts in determining sprinkler coverage for sloped and beam ceilings; revised coverage on dry type sprinkler heads; and new information on "shadow area" to help avoid ceiling fan blockage. This edition also clarifies the use of residential sprinklers outside of dwelling units. Another critical update addresses antifreeze use.
