Tyco ESFR-25 User manual

General
Description
The TYCO Model ESFR-25 Pendent
Sprinklers are “Early Suppression,
Fast Response Sprinklers” having
a nominal K-Factor of 25.2. (Refer to
Figure 1.) They are suppression-mode
sprinklers that are especially advanta-
geous as a means of eliminating the
use of in-rack sprinklers when pro-
tecting high-piled storage.
The Model ESFR-25 Sprinklers are
primarily used for ceiling-only sprin-
kler protection of (but not limited to)
the following storage applications:
• Most encapsulated or non-encap-
sulated common materials including
cartoned, unexpanded plastics.
• Uncartoned (exposed) expanded
plastics in accordance with NFPA
13 and FM Global standards.
• Some storage arrangements of
rubber tires, roll paper, ammable
liquids, aerosols, and automotive
components.
For more specic criteria, refer to
Table 1 in this data sheet as well as
the applicable design standard.
The Model ESFR-25 Sprinklers
provide the system designer with
hydraulic and sprinkler placement
options not presently available
to the traditional ESFR sprinklers
having nominal K-Factors of 14.0
and 16.8. In particular, the Model
ESFR-25 Sprinkler has been designed
to operate at substantially lower-end
head pressures, as compared to ESFR
Sprinklers having nominal K-Factors
of 14.0 and 16.8. This feature offers
exibility when sizing system piping,
as well as possibly reducing or
eliminating the need for a system re
pump.
Also, Model ESFR-25 Sprinklers per-
mit use of a maximum deector-to-
ceiling distance of 18 inches (460 mm)
versus 14 inches (360 mm). Addi-
tionally, a storage arrangement of 40
ft. (12,2 m) with a ceiling height of 45
ft. (13,7 m) does not require in-rack
sprinklers as do other ESFR Sprinklers
having nominal K-Factors of 14.0. and
16.8.
Applications for the TYCO ESFR
Sprinklers are expanding beyond cur-
rently recognized installation stan-
dards. For information on research
re tests (with ammable liquids and
aerosols, for example) that may be
acceptable to an Authority Having Ju-
risdiction, contact the Technical Ser-
vices department.
NOTICE
The Model ESFR-25 Sprinklers described
herein must be installed and maintained
in compliance with this document, as well
as with the applicable standards of the
National Fire Protection Association, in
addition to the standards of any authorities
having jurisdiction (for example, FM
Global). Failure to do so may impair the
performance of these devices.
Owners are responsible for maintaining
their fire protection system and devices in
proper operating condition. The installing
contractor or sprinkler manufacturer
should be contacted with any questions.
In all cases, the appropriate NFPA or FM
installation standard, or other applicable
standard, must be referenced to ensure
applicability and to obtain complete
installation guidelines. The general
guidelines in this data sheet are not
intended to provide complete installation
criteria.

IMPORTANT
Always refer to Technical Data
Sheet TFP700 for the “INSTALLER
WARNING” that provides cau-
tions with respect to handling
and installation of sprinkler sys-
tems and components. Improp-
er handling and installation can
permanently damage a sprin-

NOTICE
The National Fire Protection Association
(NFPA) and FM Global (FM) provide
installation standards that must be used
to properly design an automatic sprinkler
system utilizing Early Suppression,
Fast Response (ESFR) Sprinklers. The
guidelines provided by NFPA and FM
may differ. Consequently, the appropriate
standard must be used for a given
installation.
In all cases, the appropriate NFPA or FM
installation standard must be referenced
to ensure applicability and to obtain
complete installation guidelines. The
following general guidelines are not
intended to provide complete installation
criteria.

TABLE 1
COMMODITY SELECTION AND DESIGN CRITERIA OVERVIEW FOR
MODEL ESFR-25 PENDENT SPRINKLERS
Operation
The fusible link assembly is comprised
of two link halves that are joined to-
gether by a thin layer of solder. When
the rated temperature is reached, the
solder melts and the two link halves
separate, activating the sprinkler and
owing water.
Installation
The TYCO Model ESFR-25 Pendent
Sprinklers must be installed in accor-
dance with the following instructions.
NOTICE
Damage to the fusible Link Assembly
during installation can be avoided by
handling the sprinkler by the frame
arms only (that is, do not apply pres-
sure to the fusible Link Assembly),
and by using the appropriate sprinkler
wrench. Failure to do so can lead to an
unstable link assembly and premature
activation of the sprinkler. Damaged
sprinklers must be replaced.
Obtain a leak-tight 1-inch NPT sprin-
kler joint by applying a minimum-to-
maximum torque of 20 to 30 ft.lbs.
(26,8 to 40,2 Nm). Higher levels of
torque can distort the sprinkler inlet
with consequent leakage or impair-
ment of the sprinkler.
1. Install the Model ESFR-25 Pendent
Sprinkler in the pendent position
(Figure 2).
2. With pipe-thread sealant applied,
hand-tighten the sprinkler into the
sprinkler tting. Do not apply pres-
sure to the Link Assembly, and
handle the Model ESFR-25 Sprin-
kler only by the Frame arms.
3. Wrench-tighten the Model ESFR-
25 Sprinkler using only the W-
Type 1 Sprinkler Wrench (Figure 2)
and by fully engaging (seating) the
wrench on the sprinkler wrench
ats (Figure 1).
4. After installation, inspect the Link
Assembly of each Model ESFR-
25 Sprinkler for damage. In partic-
ular, verify that the Link Assembly
and Hook are positioned as illus-
trated in Figure 1, and that the Link
Assembly is not bent, creased, or
forced out of normal position in any
way. Replace damaged sprinklers.

Care and
Maintenance
The TYCO Model ESFR-25 Sprinklers
must be maintained and serviced
in accordance with the following
instructions.
NOTICE
Before closing a fire protection system
main control valve for maintenance
work on the fire protection system that
it controls, obtain permission to shut
down the affected fire protection systems
from the proper authorities and notify all
personnel who may be affected by this
action.
Exercise care to avoid damage before,
during, and after installation. Never
paint, plate, coat, or otherwise alter
automatic sprinklers after they leave
the factory.
Replace sprinklers that:
• were modied or over-heated.
• were damaged by dropping, strik-
ing, wrench twisting, wrench slip-
page, or the like.
• are leaking or exhibiting visible
signs of corrosion.
Responsibility lies with the owner for
the inspection, testing, and mainte-
nance of their re protection system
and devices in compliance with this
document, as well as with the appli-
cable standards of the National Fire
Protection Association (for example,
NFPA 25), in addition to the standards
of any authorities having jurisdiction.
Contact the installing contractor or
sprinkler manufacturer regarding any
questions.
Automatic sprinkler systems are
recommended to be inspected,
tested, and maintained by a qualied
Inspection Service in accordance with
local requirements and/or national
codes.
