Type EA-1 PROTECTOSPRAY
Directional Spray Nozzles, Automatic,
Medium Velocity
General
Description
The TYCO Type EA-1 PROTECTO-
SPRAY Directional Spray Nozzles are
automatic (frangible bulb) directional
spray nozzles designed for use in water
spray fixed systems for fire protection
applications. They are external deflec-
tor-type nozzles that discharge a uni-
formly filled cone of medium velocity
water droplets.
The Type EA-1 PROTECTOSPRAY
Directional Spray Nozzles are effective
in covering exposed vertical, horizontal,
curved, and irregular shaped surfaces
in a cooling spray to prevent excessive
absorption of heat from an external
fire and possible structural damage or
spread of fire to the protected equip-
ment. However, use of an automatic
nozzle requires consideration of the
response time of the thermal element.
The Type EA-1 PROTECTOSPRAY
Directional Spray Nozzles are also
especially effective for area cover-
age and are sometimes used in lieu of
standard sprinklers where directional
spray is considered more appropri-
ate. In some applications, depending
on water design density requirements,
the Type EA-1 Nozzles are also used for
fire control or extinguishment.
The Type EA-1 PROTECTOSPRAY
Directional Spray Nozzles are available
in three orifice sizes and a wide variety
of spray angles (included angle of dis-
charge), as well as temperature ratings

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 instal-
lation of sprinkler systems and com-
ponents. Improper handling and
installation can permanently damage
a sprinkler system or its compo-
nents and cause the sprinkler to fail
to operate in a fire situation or cause
it to operate prematurely.

to provide versatility in system design.
It is recommended that the end user be
consulted with respect to the suitabil-
ity of the materials of construction and
finish for any given corrosive environ-
ment. The effects of ambient tempera-
ture, concentration of chemicals, and
gas/chemical velocity should be con-
sidered, at a minimum, along with the
corrosive nature to which the sprinklers
may be exposed.
The Type EA-1 PROTECTOSPRAY
Directional Spray Nozzle is a re-desig-
nation for the Gem Type EA-1.
NOTICE
The Type EA-1 PROTECTOSPRAY
Directional Spray Nozzles described
herein must be installed and maintained
in compliance with this document, as
well as with the applicable standards
of the National Fire Protection Associa-
tion, in addition to the standards of any
authorities having jurisdiction. Failure
to do so may impair the performance
of these devices.
The design of individual water spray
fixed systems can vary considerably,
depending on the characteristics and
nature of the hazard, the basic purpose
of the spraying system, the configura-
tion of the hazard, and wind/draft con-
ditions. Because of these variations,
as well as the wide range of available
nozzle spray characteristics, the design
of water spray fixed systems for fire
protection must only be performed by
experienced designers who thoroughly
understand the limitations as well as
capabilities of such systems.
The owner is responsible for main-
taining their fire protection system
and devices in proper operating con-
dition. Contact the installing contrac-
tor or product manufacturer with any
questions.

Operation
The glass bulb contains a fluid that
expands when exposed to heat. When
the rated temperature is reached, the
fluid expands sufficiently to shatter the
glass bulb, allowing the nozzle to acti-
vate and water to flow.
