IMPORTANT
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 in-
stallation 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 D4a PROTECTO-
SPR AY Nozzles are open (non-auto-
matic) directional spray nozzles and
they are designed for use in water
spray xed systems for re protection
applications. They are external deec-
tor-type nozzles that discharge a uni-
formly lled cone of medium velocity
water droplets. The Type D4a Nozzles
feature a four arm body design that
helps assist against mechanical or
physical damage similar to a sprinkler
guard used on automatic sprinklers.
The Type D4a 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
re and possible structural damage or
spread of re to the protected equip-
ment. In some applications, depending
on water design density requirements,
the Type D4a Nozzles may also be
used for re control or extinguishment.
The Type D4a Nozzles are available in
a wide variety of orice sizes and spray
angles (included angle of discharge) to
provide versatility in system design.
It is recommended that the end user
be consulted with respect to the suit-
ability of the materials of construction
and nish for any given corrosive en-
vironment. The effects of ambient tem-
perature, 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 D4a PROTECTOSPRAY
Nozzle is a re-designation for the
Gem Type D4a Nozzle.
NOTICE
The TYCO Type D4a PROTECTO-
SPRAY Nozzles described herein
must be installed and maintained in
compliance with this document and
with the applicable standards of the
National Fire Protection Association,
in addition to the standards of any au-
thorities 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 pur-
pose of the spraying system, the con-
figuration of the hazard, and wind/draft
conditions. Because of these varia-
tions, as well as the wide range of
available nozzle spray characteristics,
the design of water spray fixed systems
for fire protection must only be per-
formed by experienced designers who
thoroughly understand the limitations
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.

Design
Criteria
Nozzle Placement
Where direct impingement of water
spray onto all of the protected sur-
face is required by the authority hav-
ing jurisdiction, the nozzles are to
be spaced and directed so that their
spray patterns will completely cover
the plane-of-protection with the mini-
mum required average density. How-
ever, it is recommended that indoor
nozzle spacing be 12 feet (3,7 m) or
less and that outdoor nozzle spacing
be 10 feet (3,0 m) or less. Where run-
down or slippage is planned, for exam-
ple, exposure protection of vessels per
NFPA 15, the above recommended in-
door and outdoor spacings also apply.
When used for protecting the surfaces
of a vessel, for example, the nozzles
are positioned normal to and approxi-
mately 2 feet (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 con-
ditions on the water spray patterns.
Spray Patterns
The Design Spray Proles for the noz-
zle spray angles of 65 to 180 degrees
are shown in Figure 2 and apply to
discharge pressures of 20 to 60 psi
(1,4 to 4,1 bar). Discharge pressures in
excess of 60 psi (4,1 bar) will result in
a decrease in coverage area since 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
C and D.
When the axial distance from the noz-
zle tip to the plane-of-protection is 2
feet (0,6 m) or less, the Design Spray
Prole is the same as the nominal
spray angles of 65 thru 140 degrees.
Main Pipeline Strainers
Main pipeline strainers per NFPA 15
are required for systems utilizing noz-
zles with a ow path less than 3/8
inch (9,5 mm) diameter, that is, No. 16
thru No. 24 (Table A), and for any sys-
tem where the water is likely to con-
tain obstructive material.
Installation
The TYCO Type D4a PROTECTO-
SPR AY Nozzles must be installed in
accordance with this section.
General Instructions
A leak-tight 1/2 inch NPT sprinkler
joint should be obtained by applying
a minimum-to- maximum torque of 7
to 14 ft.-lbs. (9,5 to 19,0 Nm). Higher
levels of torque can distort the sprin-
kler Inlet with consequent leakage or
impairment of the nozzle.
Step 1. With pipe-thread sealant ap-
plied to the pipe threads, hand-tighten
the nozzle into the nozzle tting.
Step 2. Tighten the nozzle into the
nozzle tting using an adjustable cres-
cent wrench. With reference to Figure
1, the adjustable crescent wrench is to
be applied to the wrenching area.

Care and
Maintenance
The TYCO Type D4a PROTECTO-
SPR AY Nozzles must be maintained
and serviced in accordance with this
section.
Before closing a re protection sys-
tem main control valve for maintenance
work on the re protection system that
it controls, obtain permission to shut
down the affected re protection sys-
tem from the proper authorities and no-
tify all personnel who may be affected
by this action.
Type D4a PROTECTOSPRAY Nozzles
must never be painted, plated, coated
or altered in any way after leaving the
factory; otherwise, the spray perfor-
mance may be impaired.
Exercise care to avoid damage to the
nozzles, before, during, and after in-
stallation. Replace nozzles damaged
by dropping, striking, wrench twist/
slippage, or the like.
Frequent visual inspections are rec-
ommended to be initially performed
for nozzles installed in potentially cor-
rosive atmospheres to verify the in-
tegrity of the materials of construction
and nish as they may be affected by
the corrosive conditions present for a
given installation. Thereafter, annual
inspections per NFPA 25 are required.
Water spray xed systems to re
protection service require regularly
scheduled care and maintenance by
trained personnel.
In addition to inspecting nozzles for
proper spray performance during wa-
ter ow trip tests of the system, it is
recommended that nozzles be peri-
odically inspected for broken or miss-
ing parts, loading/obstructions, or
other evidence of impaired protection.
The inspections should be scheduled
weekly or as frequently as may be
necessary, and corrective action must
be taken to ensure that the nozzles
will perform as intended in the event
of a re.
The owner is responsible for the in-
spection, testing, and maintenance of
their re protection system and de-
vices in compliance with this docu-
ment, as well as with the applicable
standards of the National Fire Protec-
tion Association (for example, NFPA
25), in addition to the standards of any
authorities having jurisdiction. The in-
stalling contractor or sprinkler manu-
facturer should be contacted relative
to any questions.
Water spray xed systems are recom-
mended to be inspected, tested, and
maintained by a qualied Inspection
Service in accordance with local re-
quirements and/or national codes.
