Upright and Pendent Sprinklers
Quick Response, Standard Coverage
General
Description
The 11.2 K-factor, Series ELO-
231FRB, Quick Response, Standard
Coverage, Upright and Pendent Sprin-
klers (Ref. Figure 1) are automatic
sprinklers of the frangible bulb type.
They are "quick response - spray
sprinklers" that produce a hemispheri-
cal water distribution pattern below the
deflector.
The 11.2 K-factor, ELO-231FRB Up-
right and Pendent Sprinklers were
subjected to full scale, high-piled stor-
age, fire tests to qualify their use in lieu
of 5.6 or 8.0 K-factor standard 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-231FRB Sprinklers —
making their use highly advantageous
in high density applications, such as
the protection of high-piled storage.
For in-rack applications an upright in-
termediate level version of the Series
ELO-231FRB Sprinklers can be ob-
tained by utilizing the Series ELO-
231FRB Upright Sprinkler with the
WSG-2 Guard & Shield, and a pendent
