General
Description

The TYCO Type EA-1 PROTECTO­SPRAY 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 deflec­tor-type nozzles that discharge a uni­formly 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 equip­ment. 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 cover­age and are sometimes used in lieu of
standard sprinklers where directional
spray is considered more appropri­ate. 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 dis­charge), as well as temperature ratings

IMPORTANT

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 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.

to provide versatility in system design.

It is recommended that the end user be
consulted with respect to the suitabil­ity of the materials of construction and
finish for any given corrosive environ­ment. The effects of ambient tempera­ture, concentration of chemicals, and
gas/chemical velocity should be con­sidered, 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-desig­nation 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 Associa­tion, 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 configura­tion of the hazard, and wind/draft con­ditions. 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 main­taining their fire protection system
and devices in proper operating con­dition. Contact the installing contrac­tor 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 acti­vate and water to flow.

Nozzle Placement

Where direct impingement of water
spray onto all of the protected surface
is required by the authority having juris­diction, the nozzles are to be spaced
and directed so that their spray pat­terns will completely cover the plane­of-protection with the minimum
required average density. However, it
is recommended that indoor nozzle
spacing be 12 ft (3,7 m) or less and that
outdoor nozzle spacing be 10 ft (3,0 m)
or less. Where rundown or slippage is
planned, for example, exposure protec-

recommended indoor and outdoor
spacings also apply.

When used for protecting the surfaces
of a vessel, for example, the nozzles
are positioned normal to and approx­imately 2 ft (0,6 m) from the surface.
This approach, in conjunction with
a properly selected spray angle, will
tend to make more effective use of the
spray as well as help minimize the dis­turbance effects of wind/draft condi­tions on the water spray patterns.

to 4,1 bar). Discharge pressures in
excess of 60 psi (4,1 bar) will result in a
decrease in coverage area because the
spray patterns tend to draw inwards
at higher pressures. Refer inquiries
on higher discharge pressures to the
Technical Services Department.

The maximum axial distances between
the nozzle tip and plane-of-protection,
for exposure protection, are given in
Table E and F. When the axial distance
from the nozzle tip to the plane-of­protection is 2 ft (0,6 m) or less, the
Design Spray Profile is the same as
the nominal spray angles of 65 to 140
degrees.

Heat Sensitivity

Because the Type EA-1 PROTEC­TOSPRAY Directional Spray Nozzles
are automatic nozzles, they must be
located with consideration of their
ability to detect abnormal tempera­ture increases due to fire. Therefore,
it is recommended that NFPA 13 be
reviewed with respect to the rules
that define the permitted distance
below ceilings and the spacing limita­tions for standard coverage automatic
sprinklers as a function of occupancy
hazard.

NOTICE

Do not install an Type EA-1 Nozzle if
the bulb is cracked or there is a loss
of liquid from the bulb. With the sprin­kler held horizontally, a small air bubble
should be present. The diameter of the
air bubble is approximately 3/32 in.
(2,4 mm) for the 135°F (57°C) to 1/4 in.
(6,4 mm) for the 500°F (260°C) temper­ature ratings.

Obtain a leak-tight 1/2 in. NPT nozzle
joint by applying a minimum-to-maxi­mum torque of 7 to 14 ft-lb (9,5 to 19,0
N∙m). Higher levels of torque can distort
the nozzle inlet and cause leakage or
impairment of the nozzle.

FIGURE 3

W-T YPE 11

SPRINKLER WRENCH

Step 1. With pipe-thread sealant
applied to the pipe threads, hand­tighten the nozzle into the nozzle fitting.

Step 2. Tighten the nozzle into the
nozzle fitting using only the W-Type 11
Sprinkler Wrench (Figure 3), except that
an 8 in. or 10 in. adjustable crescent
wrench is to be used for wax-coated
nozzles. With reference to Figure 1,
the W-Type 11 Sprinkler Wrench or the
adjustable crescent wrench, as appli­cable, is to be applied to the wrench­ing area.

When installing wax-coated nozzles
with the adjustable crescent wrench,
exercise additional care to prevent
damage to the wax coating on the
nozzle wrenching area or frame
arms and, consequently, exposure of
bare metal to the corrosive environ­ment. Sufficiently widen the jaws of
the wrench enough to pass over the
wrenching area without damaging the
wax coating. Before wrench-tighten­ing the nozzle, adjust the jaws of the
wrench to contact the nozzle wrench­ing area. After wrench-tightening the
nozzle, loosen the wrench jaws before
removing the wrench.

After installation, inspect the nozzle
wrenching area and frame arms and
retouch (repair) the wax coating wher­ever the coating has been damaged
and bare metal is exposed. Retouch
the wax coating on the wrenching area
by gently applying a heated 1/8 in.
diameter steel rod to the areas of wax
that have been damaged, smoothing it
back over areas where bare metal is
exposed.

NOTICE

Only retouching of the wax coating
applied to the wrenching area and
frame arms is permitted, and the
retouching is to be performed only at
the time of the initial nozzle installation.

The steel rod should be heated only
to the point at which it can begin to
melt the wax, and appropriate precau­tions need to be taken when handling
the heated rod in order to prevent the
installer from being burned.

Care and
Maintenance

The TYCO Type EA-1 PROTECTO­SPRAY Directional Spray Nozzles must
be maintained and serviced in accor­dance with this section.

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
system from the proper authorities
and notify all personnel who may be
affected by this action.

Type EA-1 PROTECTOSPRAY Direc­tional Spray Nozzles must never be
painted, plated, coated or altered in
any way after leaving the factory; other­wise, the spray performance and heat
sensitivity may be impaired.

Exercise care to avoid damage to the
nozzles before, during, and after instal­lation. Replace nozzles damaged by
dropping, striking, wrench twist/slip­page, or the like.

Frequent visual inspections are rec­ommended to be initially performed
for nozzles installed in potentially cor­rosive atmospheres to verify the integ­rity of the materials of construction and
finish as they may be affected by the
corrosive conditions present for a given
installation. Thereafter, annual inspec­tions per NFPA 25 are required.

The owner is responsible for the
inspection, testing, and maintenance of
their fire protection system and devices
in compliance with this document, as
well as with the applicable standards
of the National Fire Protection Asso­ciation (e.g., NFPA 25), in addition to
the standards of any other authorities

having jurisdiction. Contact the install­ing contractor or product manufacturer
with any questions.

Water spray fixed systems are rec­ommended to be inspected, tested,
and maintained by a qualified Inspec­tion Service in accordance with local
requirements and/or national codes.
