Tyco ELO-231B Series Manual

Series ELO-231B – 11.2 K-factor
Upright and Pendent Sprinklers
Standard Response, Standard Coverage
General
Description
TYCO Series ELO-231B 11.2K Standard
Response, Standard Coverage Upright
and Pendent Sprinklers (Ref. Figure 1)
are automatic sprinklers of the frangible
bulb type. They are standard response,
spray sprinklers that produce a hemi-
spherical water distribution pattern
below the deflector.
The 11.2 K-factor, ELO-231B 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 11.2
K-factor, ELO-231B Sprinklers, making
their use highly advantageous in high
density applications, such as the pro-
tection of high-piled storage.
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
IMPORTANT

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.
