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.

General
Description
The TYCO Type D3 PROTECTOSPRAY
Nozzles are open (non-automatic)
directional spray nozzles and they are
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 D3 Nozzles are effective in cov-
ering 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. In some applications, depending
on water design density requirements,
the Type D3 Nozzles may also be used
for fire control or extinguishment.
The Type D3 Nozzles are available in a
wide variety of orifice sizes and spray
angles (included angle of dis charge)
to provide versatility in system design.
Refer to Technical Data Sheet TFP890
for information on Blow-Off Plugs that
can be used for applications where
protection is required against insect
infestation or accumulation of debris
within the nozzle orifice.
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 sprin klers
may be exposed.
The Type D3 PROTECTOSPRAY Nozzle
is a re-designation for the Gem Type
D3.

NOTICE
The Type D3 PROTECTOSPRAY
Nozzles described herein must be
installed and maintained in compli-
ance with this document, and with the
applicable standards of the NATIONAL
FIRE PROTECTION ASSOCIATION, in
addition to the standards of any author-
ities 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.
