Model ESFR-17
Early Suppression, Fast Response Upright Sprinklers

16.8 K-Factor

General
Description

The TYCO Model ESFR-17 Upright
Sprinklers are “Early Suppression,
Fast Response Sprinklers” having a
nominal K-Factor of 16.8 (Figure 1).
They are suppression mode sprinklers
that are especially advantageous as a
means of eliminating in-rack sprinklers
when protecting high-piled storage.

Model ESFR-17 Sprinklers are
primarily used for ceiling-only sprin­kler protection of (but not limited to)
the following storage applications:

• Most encapsulated or non-encap­sulated common materials including
cartoned, unexpanded plastics.

• Cartoned, expanded plastics.

• Some storage arrangements of rub­ber tires and roll paper.

For more specic criteria, refer to
Table 1 in this data sheet as well as
the applicable design standard.

The Model ESFR-17 Upright Sprin­klers provide the system designer with
an upright option to the traditional
pendent ESFR Sprinklers. With a K­Factor of 16.8, Model ESFR-17 Sprin­klers provide system designers with
hydraulic and sprinkler placement
options not presently available to
traditional ESFR Sprinklers having
a K-Factor of 14.0. In particular, the
Model ESFR-17 Upright Sprinklers are

IMPORTANT

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.

designed to operate at substantially
lower-end head pressures compared
to ESFR Sprinklers with 14.0 K-Fac­tors. This feature offers exibility when
sizing system piping and positioning
the system piping with respect to the
ceiling.

Applications for the TYCO ESFR
Sprinklers are expanding beyond cur­rently recognized installation stan­dards. For information on research
re tests that may be acceptable to an
Authority Having Jurisdiction, contact
the Technical Services department.

NOTICE

The Model ESFR-17 Upright 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 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.
