Typically, each unit consists of a threaded pipe <br />nipple for connecting to the main or branch <br />feeder line, a flexible hose in standard lengths, <br />a reducing fitting that the sprinkler head attaches <br />to, and a mounting bracket. <br />Mounting <br />Bracket <br />The FlexHead® hose allows the head to move <br />in any direction during a seismic event without <br />causing damage to the sprinkler system. <br />Ceiling Tile <br />FlexHead° Industries recently satisfactorily completed full-scale seismic qualification testing at the Structural <br />Engineering Earthquake Simulation Laboratory located at the State University of New York at Buffalo. Tests were <br />conducted using the International Code Council (ICC) acceptance criteria "ICC-ES AC-156 Seismic Qualification <br />Testing of Nonstructural Components". <br />• More than 90% of the states in the U.S. are adopting the <br />International Building Code (IBC) that address, among <br />other things, the installation of fire sprinkler systems in <br />seismic zones. <br />• The latest version of the IBC defers to ASCE 7 for the <br />sprinkler/ceiling design in Seismic Design Categories <br />9SDC) C and D, E & F. <br />• In Seismic Design Category C, suspended ceilings are to <br />be designed and installed in accordance with Ceilings & <br />Interior Systems Construction Association (CISCA) <br />recommendations for Zones 0-2; and sprinkler heads <br />and other penetrations shall have a minimum of 1/4-inch <br />clearance on all sides. <br />• In Seismic Design Categories D, E & F, suspended <br />ceilings are to be designed and installed in accordance <br />with CISCA recommendations for seismic Zones 3 and 4 <br />with some additional requirements. Except where rigid <br />braces are used to limit lateral deflections, sprinkler heads <br />and other penetrations shall have a 2-inch oversized ring, <br />sleeve, or adapter through the ceiling to allow for free <br />movement of at least 1 inch of ceiling movement in all <br />horizontal directions. <br />• Flexible sprinkler connection provide characteristics that <br />exceed the most stringent seismic code requirements. <br />The flexibility of the hose allows the head to move with <br />the ceiling in any direction during a seismic event without <br />causing damage to the sprinkler system. <br />800.829.6975 <br />FLEXHEAV <br />INDUSTRIES-L- <br />.. o _Alaucore <br />
