Tyco’s LFII lead-free sprinkler


Johnson Controls, the global provider for smart, healthy, and sustainable buildings launches the Tyco Series LFII Residential 4.9 K-factor Lead-Free for 13D Sprinkler. The concealed pendent sprinkler is manufactured with a polymeric material that carries anti-heat and anti-corrosion properties, making it ideal for long-lasting dependable fire protection in residential occupancies.

It is the first fire sprinkler to be certified to ANSI/UL 199, the Standard for Automatic Sprinklers for Fire-Protection Service, specific to the use of polymer-based materials, by UL.

Residential fire protection

“The Tyco LFII Lead-Free Sprinkler marks a milestone in residential fire protection as the first innovation of its kind to be certified to ANSI/UL 199,” said Kerry Bell, Principal Engineer at UL.

“We were excited to work with Johnson Controls to evaluate this innovative residential sprinkler that includes polymeric construction materials. Authorities, contractors, specifiers, homeowners, and others can be confident that this new sprinkler, bearing the UL Mark, has demonstrated compliance with the requirements of ANSI/UL 199.”

It is also certified to NSF 372 and NSF 61 to ensure compatibility with safe drinking water and lead-free plumbing requirements.

This lead-free sprinkler delivers performance beyond a brass sprinkler, reduces installation costs, and meets stringent building codes. We are excited to offer this valuable addition to our product lineup,” said Anna Khanova, global VP product management, Johnson Controls.
