Series ELO-231B – 11.2 K-factor
Upright and Pendent Sprinklers
Standard Response, Standard Coverage
www.tyco-fire.com
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 hemispherical 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 protection 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 sprinklers have passed the standard corrosion tests of the applicable approval
agencies, the testing is not representative of all possible corrosive
atmospheres. Consequently, it is recommended that the end-user be consulted with respect to the suitability
of these corrosion resistant coatings
IMPORTANT
Refer to Technical Data Sheet
TFP2300 for warnings pertaining to
regulatory and health information.
Always refer to Technical Data
Sheet TFP700 for the “INSTALLER
WARNING” that provides cautions
with respect to handling and installation of sprinkler systems and components. Improper handling and
installation can permanently damage
a sprinkler system or its components and cause the sprinkler to fail
to operate in a fire situation or cause
it to operate prematurely.
for any given corrosive environment.
The effects of ambient temperature,
concentration of chemicals, and gas/
chemical velocity, should be considered, as a minimum, along with the corrosive 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 possibility of the pendent intermediate level
version being exposed to mechanical
damage, a G-2 Guard can be added.

Installation
TYCO Series ELO-231B 11.2K Standard Response, Standard Coverage
Upright and Pendent Sprinklers must
be installed in accordance with this
section.
A leak-tight 3/4 in. NPT sprinkler joint
should be obtained by applying a minimum-to-maximum torque of 10 to 20
lb-ft (13,4 to 26,8 N∙m). A leak-tight
1/2 in. NPT sprinkler joint should be
obtained by applying a minimum-tomaximum torque of 7 to 14 lb-ft (9,5
to 19,0 N∙m). Higher levels of torque
can distort the sprinkler inlet with consequent leakage or impairment of the
sprinkler.
Notes: Do not install any bulb type
sprinkler if the bulb is cracked or there
is a loss of liquid from the bulb. With
the sprinkler held horizontally, a small
air bubble should be present. The
diameter of the air bubble is approximately 1/16 in. (1,6 mm) for the 155°F
(68°C) to 3/32 in. (2,4 mm) for the
286°F (141°C) temperature ratings.
Do not attempt to make up for insufficient adjustment in the escutcheon
plate by under- or over-tightening the
sprinkler. Re-adjust the position of the
sprinkler fitting to suit.
The Series ELO-231B Upright and
Pendent Sprinklers must be installed
in accordance with the following
instructions.
Note: Pendent sprinklers are to be
installed in the pendent position;
upright sprinklers are to be installed in
the upright position.
Step 1. With pipe thread sealant
applied to the pipe threads, handtighten the sprinkler into the sprinkler
fitting.
Step 2. Tighten the sprinkler into the
sprinkler fitting using only the W-Type 3
Sprinkler Wrench (Ref. Figure 2), except
that an 8 in. or 10 in. adjustable wrench
is to be used for wax-coated sprinklers.
With reference to Figure 1, the W-Type
3 Sprinkler Wrench or the adjustable
wrench, as applicable, is to be applied
to the wrench flats.
When installing wax-coated sprinklers
with the adjustable wrench, additional
care needs to be exercised to prevent
damage to the wax coating on the
sprinkler wrench flats or frame arms
and, consequently, exposure of bare
metal to the corrosive environment.
The jaws of the wrench should be
opened sufficiently wide to pass over
the wrench flats without damaging the
wax coating. Before wrench-tightening
the sprinkler, the jaws of the wrench are
to be adjusted to just contact the sprinkler wrench flats. After wrench-tightening the sprinkler, loosen the wrench
jaws before removing the wrench.
After installation, the sprinkler
wrench flats and frame arms must
be inspected and the wax coating
retouched (repaired) whenever the
coating has been damaged and bare
metal is exposed. The wax coating on
the wrench flats can be retouched by
gently applying a heated 1/8 in. diameter steel rod to the areas of wax that
have been damaged, to smooth it
back over areas where bare metal is
exposed.
Notes: Only retouching of the wax
coating applied to the wrench flats
and frame arms is permitted, and
the retouching is to be performed
only at the time of the initial sprinkler
installation.
The steel rod should be heated only
to the point at which it can begin to
melt the wax, and appropriate precautions need to be taken, when handling
the heated rod, in order to prevent the
installer from being burned.
If attempts to retouch the wax coating
with complete coverage are unsuccessful, additional wax can be ordered
in the form of a wax stick (the end
of which is color-coded). Only the
correct color-coded wax is to be
used, and retouching of wrench flats
and frame arms is only permitted at
the time of initial sprinkler installation.
With the steel rod heated as previously described, touch the rod to the
area requiring additional wax with the
rod angled downward, and then touch
the wax stick to the rod approximately
1/2 in. away from the area requiring
retouching. The wax will melt and run
down onto the sprinkler.
Care and
Maintenance
TYCO Series ELO-231B 11.2K Standard
Response, Standard Coverage Upright
and Pendent Sprinklers must be maintained and serviced in accordance with
this section.
Before closing a fire protection system
control valve for maintenance work on
the fire protection system that it controls, permission to shut down the
affected fire protection system must
be obtained from the proper authorities
and all personnel who may be affected
by this action must be notified.
Sprinklers that are found to be leaking
or exhibiting visible signs of corrosion
must be replaced.
Automatic sprinklers must never be
painted, plated, coated or otherwise altered after leaving the factory.
Modified sprinklers must be replaced.
Sprinklers that have been exposed to
corrosive products of combustion, but
have not operated, should be replaced
if they cannot be completely cleaned
by wiping the sprinkler with a cloth or
by brushing it with a soft bristle brush.
Care must be exercised to avoid
damage to the sprinklers before,
during, and after installation. Sprinklers damaged by dropping, striking,
wrench twist/slippage, or the like, must
be replaced. Also, replace any sprinkler that has a cracked bulb or that has
lost liquid from its bulb. For additional
information, refer to Installation section.
Frequent visual inspections are recommended to be initially performed
for corrosion resistant sprinklers, after
the installation has been completed, to
verify the long term potential integrity
of the sprinkler coatings. Thereafter,
annual inspections per NFPA 25 should
suffice; however, instead of inspecting
from the floor level, a random sampling
of close-up visual inspections should
be made, so as to better determine the
exact sprinkler condition and the long
term integrity of the corrosion resistant
coating, as it may be affected by the
corrosive conditions present.
The owner is responsible for the
inspection, testing, and maintenance of
their fire protection system and devices
in compliance with this document, as
well as with the applicable standards
of the National Fire Protection Association, such as NFPA 25, in addition to
the standards of any other authorities
having jurisdiction. Contact the installing contractor or product manufacturer
with any questions.
