Tyco Fire Product Star Pulsar ESFR-25 User manual

Early Suppression Fast Response
Pendent Sprinklers ,
Pulsar™ ESFR-25™, K=25.2
GENERAL DESCRIPTION
The Star Pulsar ESFR-25 Pendent Sprinklers (Ref. Figure
1) are “Early Suppression Fast Response Sprinklers” hav-
ing a nominal K-factor of 25.2. They are suppression
mode sprinklers, and their use is especially advanta-
geous as a means of eliminating the use of in-rack sprin-
klers, when protecting high-piled storage.
The Pulsar ESFR-25 is primarily designed for use with
storage heights of most encapsulated or non-encapsu-
lated common materials including cartoned unexpanded
plastics of up to 40 ft. (12,2 m) and with ceiling heights of
up to 45 ft. (13,7 m). In addition, the protection of some
storage arrangements of roll paper and rubber tires can
be considered as well.
The Pulsar ESFR-25 provides the system designer with
hydraulic and sprinkler placement options not presently
available to the traditional ESFR sprinklers having a nomi-
nal K-Factor of 14.0. In particular, the Pulsar ESFR-25
has been designed to operate at substantially lower end
head pressures, as compared to ESFR sprinklers having
a nominal K-Factor of 14.0. This feature offers flexibility
when sizing the system piping, as well as possibly reduc-
ing or eliminating the need for a system fire pump. Also,
the Pulsar ESFR-25 permits use of a maximum deflector-
to ceiling distance of 18 inches (460 mm) versus 14
inches (360 mm); and, a storage arrangement of up to 40
ft. (12,2 m) with a ceiling height of up to 45 ft. (13,7 m)
does not require in-rack sprinklers as do ESFR sprinklers
having a nominal K-Factor of 14.0.
The Pulsar ESFR-25 Pendent Sprinkler is also Listed by
Underwriters Laboratories Inc. (UL) and by UL for use in
Canada (C-UL) as a “Specific Application Early Suppres-
sion Fast Response Sprinkler” as indicated under the UL
and C-UL Specific Application Design Criteria section.
The specific application listing provides for reduced pres-
sure design for the protection of certain commodities.
Applications for the Pulsar ESFR-25 Sprinklers are ex-
panding beyond the current recognized installation stand-
ards. For information regarding research fire tests which
may be acceptable to an Authority Having Jurisdiction
(e.g., flammable liquids, exposed plastics, and aerosols),
please contact the Technical Services Department.
WARNINGS
The Pulsar ESFR-25 Sprinklers described herein must be
installed and maintained in compliance with this docu-
ment, as well as with the applicable standards of the Na-
tional Fire Protection Association, in addition to the stand-
ards of any other authorities having jurisdiction (e.g.,
Factory Mutual Research Corporation). Failure to do so
may impair the integrity of these devices.
The owner is responsible for maintaining their fire protec-
tion system and devices in proper operating condition.
The installing contractor or sprinkler manufacturer should
be contacted relative to any questions.
OPERATION
The fusible link (heat collector) assembly is comprised of
two link halves which are joined together by a thin layer
of solder. When the rated temperature is reached, the sol-
der melts and the two link halves separate, which then al-
lows the sprinkler to activate and flow water.

INSTALLATION
The Pulsar ESFR-25 Pendent Sprinklers are to be in-
stalled in accordance with the following instructions:
NOTE
Damage to the fusible Link Assembly during installation
can be avoided by handling the sprinkler by the frame
arms only (i.e., do not apply pressure to the fusible Link
Assembly), and by using the appropriate sprinkler
wrench. Damaged sprinklers must be replaced.
A leak tight 1 inch NPT sprinkler joint should be obtained
withatorqueof20to30ft.lbs.(26,8to40,2Nm).Higher
levels of torque may distort the sprinkler inlet with conse-
quent leakage or impairment of the sprinkler.
1. The Pulsar ESFR-25 Sprinkler must be installed in the
pendent position.
2. With pipe thread sealant applied, hand tighten the sprinkler
into the sprinkler fitting. Do not apply pressure to the Link
Assembly, and handle the Pulsar ESFR-25 Sprinkler only
by the Frame arms.
3. Wrench tighten the Pulsar ESFR-25 Sprinkler using only
the W-Type 1 Sprinkler Wrench (Ref. Figure 2) and by fully
engaging (seating) the wrench with the sprinkler wrench
flats.
4. After installation, inspect the Link Assembly of each Pulsar
ESFR-25 Sprinkler for damage. In particular, verify that the
Link Assembly and Hook are positioned as illustrated in
Figure 1, and that the Link Assembly has not been bent,
creased, or forced out of its normal position in any way.
Damaged sprinklers must be replaced.
CARE AND MAINTENANCE
The Pulsar ESFR-25 must be maintained and serviced in
accordance with the following instructions:
NOTE
Before closing a fire protection system main control valve
for maintenance work on the fire protection system which
it controls, permission to shut down the affected fire pro-
tection systems must be obtained from the proper authori-
ties and all personnel who may be affected by this action
must be notified.
Sprinklers which are found to be leaking or exhibiting vis-
ible signs of corrosion must be replaced.
Automatic sprinklers must never be shipped or stored
where their temperature will exceed 100°F/38°C and they
must never be painted, plated, coated, or otherwise al-
tered after leaving the factory. Modified or over-heated
sprinklers must be replaced.
Care must be exercised to avoid damage - before, dur-
ing, and after installation. Sprinklers damaged by drop-
ping, striking, wrench twist/slippage, or the like, must be
replaced.
The owner is responsible for the inspection, testing, and
maintainance of their fire protection system and devices
in compliance with this document, as well as with the ap-
plicable standards of the National Fire Protection Associa-
tion (e.g., NFPA 25), in addition to the standards of any
other authorities having jurisdiction. The installing contrac-
tor or sprinkler manufacturer should be contacted relative
to any questions.
It is recommended that automatic sprinkler systems be in-
spected, tested, and maintained by a qualified Inspection
Service.
