Series ELO-231B - 11.2 K-factor
Upright and Pendent Sprinklers
Standard Response, Standard Coverage


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 representative 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.

Procedure
 
A Part Number (P/N) is not specified when ordering sprinklers with thread connections per ISO 7/1.
 
Contact your local distributor for avail-ability.
 
Sprinkler Assemblies
with NPT Thread Connection:
 
Specify: (specify SIN), 11.2 K-factor, (specify temperature rating), Series ELO-231B Standard Response (spec-ify Pendent or Upright) Sprinkler with (specify finish), P/N (specify from Ta-ble B).
 
Sprinkler Wrench:
Specify: W-Type 3 Sprinkler Wrench,
P/N 56-895-1-001.
 
Wax Sticks:
 
(for retouching wrench damaged wax coating)

NOTES
 
Each wax stick is suitable for retouch-ing up to twenty-five sprinklers.
 
The wax used for 286°F sprinklers is the same as for 200°F sprinklers, and, therefore, the 286°F sprinkler is limited to the same maximum ceiling tempera-ture as the 200°F sprinkler (i.e., 150°F).
