Series ELO-231FRB – 11.2 K-factor
Upright and Pendent Sprinklers
Quick Response, Standard Coverage
General
Description
TYCO Series ELO-231FRB 11.2K Quick
Response, Standard Coverage, Upright
and Pendent Sprinklers (Ref. Figure 1)
are automatic sprinklers of the frangi-
ble bulb type. They are quick response
spray sprinklers that produce a hemi-
spherical water distribution pattern
below the deflector.
The 11.2K ELO-231FRB Upright and
Pendent Sprinklers were subjected to
full scale, high-piled storage 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 11.2K
ELO-231FRB Sprinklers, making
their use highly advantageous in high
density applications, such as the pro-
tection of high-piled storage.
For in-rack applications, an upright
intermediate level version of the
Series ELO-231FRB Sprinklers can
be obtained by utilizing the Series
ELO-231FRB Upright Sprinkler with
the WSG-2 Guard & Shield, and a
pendent intermediate level version
of the Series ELO-231FRB Sprinklers
can be obtained by utilizing the Series
ELO-231FRB Pendent Sprinkler with
the WS-2 Shield. If there is a possibil-
ity of the pendent intermediate level
version being exposed to mechanical
damage, a G-2 Guard can be added.
IMPORTANT
Always refer to Technical Data
Sheet TFP700 for the "INSTALLER
WARNING" that provides cautions
with respect to handling and instal-
lation of sprinkler systems and com-
ponents. Improper handling and
Installation can permanently damage
a sprinkler system or its compo-
nents and cause the sprinkler to fail
to operate in a fire situation or cause
it to operate prematurely.
