Model GS256, 5.6 K-factor Horizontal Sidewall Sprinklers Standard Response

• GENERAL DESCRIPTION 
  • Horizontal sidewall sprinklers aredesigned for installationalongawall or thesideof abeamand are commonly used instead of pendent or upright sprinklers due to aesthetics or building construction considerations, where piping across theceiling isnotdesirable.
  • Corrosion resistant coatings, whereapplicable,are utilized toextend the lifeof copper alloysprinklers beyond that which would otherwise be obtained when exposed to corrosive atmospheres. Although corrosion resistant coated sprinklers have passed the standard corrosion tests of the applicable approval agencies, the testing is not representative of all possible corrosive atmospheres. Consequently, it is recommended that theenduser beconsultedwith respect to the suit-ability of these corrosion resistant coatings for anygivencorrosiveenvironment. Theeffectsof ambient temperature, concentration of chemicals, and gas/chemical velocity, should be considered, asaminimum,alongwiththecorrosivenatureof the chemical towhichthesprinklerswillbeexposed
