1 1 of 6 MArch, 2007 TFP342_ENGeneral Description The 160 K-factor, Series ELO-231B , Standard Response, Standard Coverage, Upright and Pendent Sprinklers (Ref. Figure 1) are auto-matic sprinklers of the frangible bulb type. They are standard response - spray sprin-klers that produce a hemispherical water distribution pattern below the deflector. The K160, ELO-231B Sprinklers were sub-jected to full scale, high-piled storage fire tests to qualify their use in lieu of 80 or 115 K-factor standard spray sprinklers for the protection of high-piled storage. Higher flow rates can be achieved at much lower pressures with the K160, ELO-231B Sprinklers making their use highly ad-vantageous in high density applications, such as the protection of high-piled stor-age.

2 Wax or lead coatings can be used to extend the life of the copper alloy components used in Series ELO-231B sprinklers beyond that which would otherwise be obtained when exposed to corrosive atmospheres. Although wax, lead, and polyester coated sprinklers have passed the standard cor-rosion tests of the applicable approval agencies, the testing is not representative of all possible corrosive atmospheres. Con-sequently, it is recommended that the end user be consulted with respect to the suit-ability of these corrosion resistant coatings for any given corrosive environment. The effects of ambient temperature, concentra-tion of chemicals, and gas/chemical velocity, should be considered, as a minimum, along with the corrosive nature of the chemical to which the sprinklers will be exposed.

3 An upright intermediate level version of the Series ELO-231B Sprinklers for in-rack ap-plications can be obtained by utilizing the Series ELO-231B Upright Sprinkler with the WSG-2 Guard & Shield, and a pendent in-termediate level version of the Series ELO-231B Sprinklers can be obtained by utiliz-ing the Series ELO-231B Pendent Sprinkler with the WS-2 Shield. If there is a possibility of the pendent intermediate level version being exposed to mechanical damage, a G-2 Guard can be K160, Series ELO-231B Upright and Pen-dent Sprinklers described herein must be in-stalled and maintained in compliance with this document, as well as with the applicable standards of the National fire Protection As-sociation, in addition to the standards of any other authorities having jurisdiction.

4 Failure to do so may impair the performance of these devices. The owner is responsible for maintaining their fire protection system and devices in proper operating condition. The installing contrac-tor or manufacturer should be contacted with any questions. Installation of Series ELO-231B Pendent Sprin-klers in recessed escutcheons will void all sprinkler warranties, as well as possibly void the sprinkler s Approvals and/or Listings. IMPORTANTA lways refer to Technical Data Sheet TFP700 for the INSTALLER WARNING that provides cautions with respect to handling and installation of sprinkler systems and components. Improper handling and installation can perma-nently damage a sprinkler system or its components and cause the sprin-kler to fail to operate in a fire situa-tion or cause it to operate ELO-231B 160 K-factor Upright and Pendent Sprinklers Standard Response, Standard CoverageGeneralDescriptionThe K-factor, Series ELO-231B ,Standard Response, Standard Cover-age, Upright and Pendent Sprinklers(Ref.)
