Fire sprinkler systems are mandated by the "local jurisdiction having authority" (the fire department). Since we comply with NFPA (National Fire Protection Association) Chapter 13 regarding the installation of these systems, the process generally starts with the fire department. Most fire departments comply with NFPA 13. NFPA writes the fire code for everything relating to the potential of fire, from electrical to fire sprinkler systems. the local jurisdiction officially mandates the requirements. In most areas all fire sprinkler systems with more than 100 heads require monitoring by a local UL Central Station. All equipment and wire must be UL listed for its intended use. the UL Listed CC2 Combustible Concealed Sprinkler features a 5.6 K-factor, an increased maximum coverage area from 100 square feet to 144 square feet, increased maximum spacing from 10 feet to 12 feet, and can be use with wet or dry pipe sprinkler systems. The best way to avoid any conflict with these officials is to have a service contract that satisfies their requirements. Not only do we design and install fire sprinkler systems, we provide quarterly inspections and annual testing as required by NFPA 25.
