BUILDING CONNECTIONS THAT LAST FLEXHEAD®SATISFIES SEISMIC CODE REQUIREMENTS The FlexHHead ' hose allows the head to move in any direction during a seismic event without causing damage Y- to the sprinkler system. FlexHead°' Mounting Bracket FlexHeade satisfactorily completed full-scale seismic qualification testing at the Structural Engineering Earthquake Simulation Laboratory located atthe State University of New York at Buffalo. Tests were conducted using the International Code Council (ICC) acceptance criteria "ICC-ES AC-156 Seismic Qualification Testing of Nonstructural Components". • More than 90% of the states in the U.S. are adopting the International Building Code (IBC) that address, among otherthings, the installation of fire sprinkler systems in seismic zones. • The latest version of the IBC defers to ASCE 7 and ASTM E580/58OM-17 forthe sprinkler/ceiling design in Seismic Design Categories C and D, E & F. In Seismic Design Category C, suspended ceilings are to be designed and installed in accordance with Ceilings & Interior Systems Construction Association (CISCA) recommendations forZones 0-2; and sprinkler heads and other penetrations shall have a minimum of 1/4 inch clearance on all sides. In Seismic Design Categories D, E & F, suspended ceilings are to be designed and installed in accordance with CISCA recommendations for seismic Zones 3 and 4 with some additional requirements. Except where rigid braces are used to limit lateral deflections, sprinkler heads and other penetrations shall have a 2-inch oversized ring, sleeve, or adapter through the ceiling to allow forfree movement of at least 1 inch of ceiling movement in all horizontal directions. • Flexible sprinkler connection provide characteristics that exceed the most stringent seismic code requirements. The flexibility of the hose allows the head to move with the ceiling in any direction during a seismic event without causing damage to the sprinkler system. 5
