Early Suppression Fast Response
Pendent Sprinklers,
Pulsar™ ESFR-1, K=14.0

GENERAL DESCRIPTION

The Star Pulsar ESFR-1 Sprinklers (Ref. Figure 1) are
"Early Suppression Fast Response Sprinklers" having a
nominal K-factor of 14.0. They are suppression mode
sprinklers, and their use is especially advantageous as a
means of eliminating the use of in-rack sprinklers, when
protecting high-piled storage.
The Pulsar ESFR-1 is primarily designed for use with stor-
age heights of most encapsulated or non-encapsulated
common materials including cartoned unexpanded plas-
tics of up to 35 ft. (10,7 m). In addition, the protection of
some storage arrangements of roll paper and rubber tires
can be considered as well.
Applications for the Pulsar ESFR-1 Sprinklers are expand-
ing beyond the current recognized installation standards.
For information regarding research fire tests which may
be acceptable to an Authority Having Jurisdiction (e.g.,
flammable liquids, aerosols, etc.), please contact the
Technical Services Department.
WARNINGS
The Pulsar ESFR-1 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.
