Johnson Controls has announced that its Tyco Series LFII Residential 4,9 K-factor, lead-free sprinkler is now approved for installation in low-rise residential properties per NFPA 13R. The Tyco LFII sprinkler is the first ANSI/UL 199 approved polymeric fire sprinkler to offer long-lasting, dependable protection for a wide range of residential buildings specified under NFPA 13D and 13R. This includes low-rise residential structures of four stories or less as scoped under NFPA 13R, as well as one-and two-family homes of any size as scoped under NFPA 13D.
“With this new UL approval, authorities, contractors, specifiers and homeowners can now protect their low-rise residential occupancies with the polymeric sprinkler,” said Anna Khanova, global vice president for product management, Johnson Controls. “We’re excited to offer our customers this industry-first sprinkler as the clear choice for helping to improve fire suppression system performance, reduce installation costs and meet stringent building codes for a wide range of residential projects.”
The LFII is manufactured with a polymeric material with anti-heat and anti-corrosion properties. These properties help to extend the life and value of the sprinkler compared to similar brass products. The sprinkler is certified to NSF 372 and NSF 61 to ensure compatibility with safe drinking water and lead-free plumbing requirements.
The concealed pendent sprinkler is available in both ordinary 68°C and intermediate 93°C temperature configurations. The sprinkler and cover plate assembly allow for adjustment by up to 1,9 cm, which provides additional flexibility with residential installations.
