Tyco ELO-231B Series Manuals

General Description The 11.2 K-factor, Series ELO-231B, Standard Response, Standard Cover- age, Upright and Pendent Sprinklers (Ref. Figure 1) are automatic sprin- klers of the frangible bulb type. They are “standard response - spray sprin- klers” that produce a hemispherical water distribution pattern below the deflector. The 11.2 K-factor, ELO-231B Sprin- klers were subjected to full scale, high- piled storage, fire tests to qualify their use in lieu of 5.6 or 8.0 K-factor stand- ard spray sprinklers for the protection of high-piled storage. Higher flow rates can be achieved at much lower pressures with the 11.2 K-factor, ELO-231B Sprinklers — making their use highly advantageous in high density applications, such as the protection of high-piled storage. Wax or lead coatings can be used to extend the life of the copper alloy com- ponents used in Series ELO-231B sprinklers beyond that which would otherwise be obtained when exposed to corrosive atmospheres. Although wax, lead, and polyester coated sprin- klers have passed the standard corro- sion tests of the applicable approval agencies, the testing is not repre- sentative of all possible corrosive at- mospheres. Consequently, it is recom- mended that the end user be consulted with respect to the suitability of these corrosion resistant coatings for any given corrosive environment. The ef- fects of ambient temperature, concen- tration of chemicals, and gas/chemical velocity, should be considered, as a minimum, along with the corrosive na- ture of the chemical to which the sprin- klers will be exposed. An upright intermediate level version of the Series ELO-231B Sprinklers for in-rack applications can be obtained by utilizing the Series ELO-231B Up- right Sprinkler with the WSG-2 Guard & Shield, and a pendent intermediate 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 interme- diate level version being exposed to mechanical damage, a G-2 Guard can be added. WARNINGS The 11.2 K-factor, Series ELO-231B Upright and Pendent Sprinklers de- scribed herein must be installed and maintained in compliance with this document, as well as with the applica- ble standards of the National Fire Pro- tection Association, in addition to the standards of any other authorities hav- ing jurisdiction. Failure to do so may impair the performance of these de- vices. The owner is responsible for maintain- ing their fire protection system and de- vices in proper operating condition. The installing contractor or manufac- turer should be contacted with any questions. Installation of Series ELO-231B Pen- dent Sprinklers in recessed escutch- eons will void all sprinkler warranties, as well as possibly void the sprinkler’s Approvals and/or Listings.

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 sprin- klers have passed the standard corro- sion tests of the applicable approval agencies, the testing is not repre- sentative of all possible corrosive atmospheres. Consequently, it is rec- ommended that the end-user be con- sulted with respect to the suitability of these corrosion resistant coatings for any given corrosive environment. The effects of ambient temperature, concentration of chemicals, and gas/ chemical velocity, should be consid- ered, as a minimum, along with the cor- rosive nature of the chemical to which the sprinklers will be exposed. An upright intermediate level version of the Series ELO-231B Sprinklers for in-rack applications can be obtained by utilizing the Series ELO-231B Upright Sprinkler with the WSG-2 Guard & Shield, and a pendent intermediate level version of the Series ELO-231B Sprinklers can be obtained by utilizing the Series ELO-231B Pendent Sprinkler with the WS-2 Shield. If there is a pos- sibility of the pendent intermediate level version being exposed to mechanical damage, a G-2 Guard can be added. NOTICE The 11.2 K-factor, Series ELO-231B Upright and Pendent Sprinklers described herein must be installed and maintained in compliance with this document, as well as with the applica- ble standards of the National Fire Pro- tection Association (NFPA), in addition to the standards of any other authori- ties having jurisdiction. Failure to do so may impair the performance of these devices. The owner is responsible for main- taining their fire protection system and devices in proper operating con- dition. Contact the installing contrac- tor or product manufacturer with any questions. Installation of Series ELO-231B Pendent Sprinklers in recessed escutcheons will void all sprinkler warranties, as well as possibly void the sprinkler’s Approvals and/or Listings.
