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.

NOTICE
The TYCO Model TN-25 Horizontal
Spray Nozzle described herein must
be installed and maintained in compli-
ance with this document and with the
applicable standards recognized by any
authorities having jurisdiction. Failure
to do so may impair the performance
of these devices.
The design of individual fixed water
spray systems for fire protection
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/ventilation
conditions. Because of these varia-
tions, the design of fixed water spray
systems must only be performed by
experienced designers who thoroughly
understand the limitations as well as
capabilities of such systems.
The Tunnel Operator is responsible for
maintaining their fire protection system
and devices in proper operating con-
dition. Contact the installing contrac-
tor or product manufacturer with any
questions.
General
Description
The TYCO Model TN-25 Horizontal
Spray Nozzle having a 25.2 (K360)
K-factor is a specialized open nozzle
for use in tunnel fire protection deluge
systems, providing an improved alter-
native to traditional designs. With its
ability to provide extended coverage,
the Model TN-25 Nozzle allows for a
single pipe to run the length of a tunnel,
compared to traditional designs that
use multiple pipes in order to provide
sufficient coverage. The Model TN-25
Nozzle is an open nozzle designed to
be integrated into a deluge fire protec-
tion system.
The Model TN-25 Nozzle provides
protection of coverage areas up to
16 ft 4 in. x 24 ft 7 in. (5,0 m x 7,5 m)
as compared to standard coverage
sprinklers often used in tunnel fire
protection system designs having a
maximum coverage area of 10 ft x 10 ft
(3,0 m x 3,0 m).

Design
Criteria
The TYCO Model TN-25 K=25.2 Hor-
izontal Spray Nozzle is intended for
integration into a water spray, deluge
fire protection system designed in
accordance with the applicable stan-
dards recognized by any authorities
having jurisdiction.
Nozzle Orientation
The Model TN-25 Nozzle must be
installed in a horizontal orientation.
See Figures 1 and 3.
Corrosion Resistance
It is recommended that the Tunnel
Operator 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 nozzles may be exposed.
The pipe, fittings, hangers, and hanger
components must be suitable for use in
the application environment.
Obstructions
The maximum allowable vertical and
horizontal distance that the bottom of
an obstruction can be away from the
Model TN-25 Nozzle is provided in
Graph A.
Non-continuous suspended obstruc-
tions such as air handlers, lights, and
the like are to meet the “4x rule” of
Figure 6; within 5 ft (152,4 cm) of the
nozzle deflector in the area below the
nozzle, the obstruction must be located
four (4) times the longest dimension of
the obstruction as defined in Figure
6, to a maximum of 60 in. (152,4 cm).
No obstructions are allowed to be
located within the designated shaded
region. Care must be taken to place
large obstructions running parallel to
the nozzle discharge, such as signs, in
the areas between the nozzles.

Installation
The TYCO Model TN-25 K=25.2 Hor-
izontal Spray Nozzle, as shown in
Figures 1 and 3, must be installed in
accordance with this section.
NOTICE
The Model TN-25 Nozzle must be
installed in accordance with the pipe
dimensions shown in Figure 2. Failure
to do so will impair the intended perfor-
mance of the system.
General Instructions
The Model TN-25 Nozzle is to be ori-
ented horizontally with the plane
created by its two frame arms paral-
lel with the ceiling or parallel with the
finished grade, in the case of a non-flat
ceiling.
Step 1. Ensure all piping components
are properly assembled as shown in
Figure 3 prior to installing the Model
TN-25 Nozzle.
Step 2. With pipe-thread sealant
applied to the nozzle threads, hand-
tighten the Model TN-25 Nozzle into
the Reducer.
Step 3. The Model TN-25 Nozzle must
be tightened using only the W-Type 1
Sprinkler Wrench as shown in Figure 2.
Fully engage the nozzle wrench flats as
shown in Figure 1 and wrench tighten. A
leak-tight 1 in. NPT or ISO 7-R 1 sprin-
kler joint should be obtained by apply-
ing a minimum-to-maximum torque
of 20 to 30 ft-lb (26,8 to 40,2 N∙m).
Higher levels of torque can distort the
nozzle inlet with consequent leakage or
impairment of the nozzle. Ensure the
markings on the deflector face towards
the ceiling.
Care and
Maintenance
The TYCO Model TN-25 K=25.2 Hor-
izontal Spray Nozzle must be main-
tained 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, permission to shut down the
affected fire protection system must be
obtained from the proper authorities
and notify all personnel who may be
affected by this action.
Nozzles which are exhibiting visible
signs of corrosion must be replaced.
Care must be exercised to avoid
damage to the nozzles before, during,
and after installation. Nozzles damaged
by dropping, striking, wrench twist/
slippage, or the like, must be replaced.
See the Installation section for addi-
tional information.
The Tunnel Operator is responsi-
ble for the inspection, testing, and
maintenance of their fire protection
system and devices in compliance
with this document, in addition to the
standards of any authorities having
jurisdiction. Contact the installing con-
tractor or product manufacturer with
any questions.
Fire protection systems are recom-
mended to be inspected, tested, and
maintained by a qualified Inspec-
tion Service in accordance with local
requirements and/or national codes.
