IMPORTANT
Always refer to Technical Data
Sheet TFP700 for the “INSTALLER
WARNING” that provides cau-
tions with respect to handling
and installation of sprinkler sys-
tems and components. Improp-
er handling and installation can
permanently damage a sprin-
kler system or its components
and cause the sprinkler to fail
to operate in a fire situation or cause
it to operate prematurely.

General
Description
The TYCO Type D3 PROTECTO-
SPRAY Nozzles are open (non-auto-
matic) directional spray nozzles and
they are 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 D3 Nozzles are effective in cov-
ering exposed vertical, horizontal,
curved, and irregular shaped surfaces
in a cooling spray to prevent exces-
sive absorption of heat from an exter-
nal fire and possible structural dam-
age or spread of fire to the protected
equipment. In some applications, de-
pending on water design density re-
quirements, 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 suit-
ability of the materials of construc-
tion and finish for any given corrosive
environ ment. The effects of ambient
tempera ture, concentration of chem-
icals, and gas/chemical velocity,
should be considered, at a minimum,
along with the corrosive nature to
which the sprin klers may be exposed.
The Type D3 PROTECTOSPRAY Noz-
zle is a re-designation for the Gem
Type D3.
NOTICE
The Type D3 PROTECTOSPRAY Noz-
zles described herein must be in-
stalled and maintained in compliance
with this document, and with the ap-
plicable standards of the National Fire
Protection Association, in addition to
the standards of any authorities having
jurisdiction. Failure to do so may im-
pair 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 pur-
pose of the spraying system, the con-
figuration 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 sys-
tems for fire protection must only be
performed by experienced designers
who thoroughly understand the limi-
tations as well as capabilities of such
systems.
The owner is responsible for maintain-
ing their fire protection system and
devices in proper operating condition.
The installing contractor or sprinkler
manufacturer should be contacted
with any questions.
