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
components. 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 Model WS Specic
Application Window Sprinklers are fast
response, glass bulb-type spray sprin-
klers available in Horizontal Sidewall
and Pendent Vertical Sidewall models.
These sprinklers are the rst to be
specically Listed to provide complete
wetting and coverage for heat strength-
ened, tempered, or ceramic glass
windows using closed sprinklers.
As part of the testing, the gas ow
required to achieve the time/temper-
ature relationship specied in ASTM
E119 was established in a test furnace
without sprinkler protection. A window
assembly protected with the TYCO
Model WS Window Sprinklers was
then installed in the test furnace, and
the same gas ow conditions were
maintained for a two-hour test period.
No cracking or visible damage to the
window was permitted during the test
period, even when a hose stream was
directed at the window.
The success of the Model WS Window
Sprinklers is based on their fast
response thermal sensitivity and on
their specially designed deectors that
ensure that the spray pattern wets the
entire surface of the window.
Based on successful testing, the
Model WS Window Sprinklers can be
used as interior protection of windows
or glazing in a sprinklered building or
non-sprinklered building in accordance
with Section 104 of the IBC (“Alternate
Materials, Design and Methods of
Construction and Equipment”). Also,
the Model WS Window Sprinklers
can be used as an open sprinkler for
“Outside Sprinkler Protection against
Exposure Fire”, using the design
requirements of NFPA.
As with any specic application sprin-
kler, the installation instructions
included in this data sheet must be
precisely followed. If there are addi-
tional local or jurisdictional installation
standards/codes for window sprinklers
on glazed window systems, this docu-
ment does not relieve the designer/
installer from these requirements.
Consult your local jurisdiction to verify
if or when these additional guidelines
must be followed.

The glass bulb contains a uid that
expands when exposed to heat. When
the rated temperature is reached, the
uid expands sufciently to shatter the
glass bulb, allowing the sprinkler to
activate and water to ow.

Intermediate Horizontal Mullions were
not tested with the Model WS Window
Sprinklers. Their use is outside the
scope of the “Specic Application”
Listing for the window sprinklers. Refer
to Figure 3B-3.
Deflector Location
Sprinkler Deectors must be located as
described below in order to ensure that
the entire surface of the glass window
is covered. Sprinkler Deectors are
positioned with respect to the window
frame, not the ceiling.
• Horizontal Sidewall: Locate within the
outside edge of the window frame
from 1/2 to 4 in. (12,7 mm to 101,6
mm) away from the glass and 2 ± 1
in. (50,8 mm ± 25,4 mm) down from
the top of the exposed glass. Refer
to Figure 3C.
• Pendent Vertical Sidewall: Locate
4 to 12 in. (101,6 mm to 304,8 mm)
from the face of the glass and 3 ± 1
in. (76,2 mm ± 25,4 mm) down from
the top of exposed glass. Refer to
Figure 3D.
Minimum Clearance from Face of
Glass to Combustible Materials
For glass types other than FireLite
Plus WS ceramic glass by TGP, all
combustible materials shall be kept
2 in. (50,8 mm) from the front face of
the glass. This can be accomplished
by a minimum 36 in. (914,4 mm) pony
wall or other method acceptable to the
authority having jurisdiction.
Escutcheon Assemblies
The Model WS Window Sprinklers
can be used with any metallic ush or
extended escutcheons, provided the
dimensions from the sprinkler deector
to the window frame and glass surface
as specied in this data sheet are
maintained. These sprinklers are not
listed for recessed applications.
Recommended Hydraulic
Requirements
The authority having jurisdiction should
be consulted to determine the hydraulic
requirements for each installation.
Interior Protection Sprinklered
Building
Identify which compartmented area
has the most hydraulically demanding
window sprinklers. Calculate up to the
most demanding 46.5 linear feet of
Model WS Window Sprinklers on one
side of the glazing. The 46.5 linear feet
(14,2 linear meters) is based upon 1.2
x the square root of the system area
of operation, when the system area of
operation is 1500 sq.-ft. in accordance
with NFPA 13 Light/Ordinary Hazard
density curves.

TFP620
Page 4 of 8
Where the area of Glazing is less than
14.2 linear meters, all window sprinklers
on one side shall be calculated.
If an area reduction for quick response
sprinklers is utilized, the linear length of
the calculated window sprinklers may
be reduced, but in no case shall be less
than 36 linear feet (1.2 x √900).
If a single re can be expected to
operate Model WS Window Sprinklers
and sprinklers within the design area of
a hydraulically calculated system, the
water demand of the window sprinklers
shall be added to the water demand
of the hydraulic calculations and shall
be balanced to the calculated area
demand.
If the window sprinklers are located in
an area other than the hydraulic design
area, the demand of the window sprin-
klers is not required to be added to
the demand of the remote hydraulic
design area. However, it is necessary
to prove hydraulically the simultaneous
operation of the Model WS Window
Sprinklers and the ceiling sprinklers
adjacent to the window sprinklers.
Interior Protection Non-Sprinklered
Building
Calculate all sprinklers on the most
demanding side of the glazing
assembly within the enclosure.
Exterior Exposure Protection
Calculate all sprinklers controlled by the
deluge valve using the design require-
ments of NFPA.
Duration of Water Supply
Duration of water supply must comply
with requirements of NFPA. If window
sprinklers are used to provide the
equivalency of a re rating, the water
supply must be capable of supplying
water for the required rating period.
Minimum Flow per Sprinkler
20 GPM (75,7 LPM) for sprinkler
spacing of 6 to 8 ft. (1,83 to 2,44 m)
or 15 GPM (56,8 LPM) for sprinkler
spacing less than 6 ft. (1,83 m).
Maximum Pressure per Sprinkler
• Horizontal Sidewall: 70 psi (4,83 bar)*
* The 70 psi is only for cold solder
purposes. If there is a bafe or a
mullion of sufcient depth to act as a
bafe, separating the sprinklers, the
maximum pressure is 175 psi (12,07
bar).
• Vertical Sidewall: 175 psi (12,07 bar)

Installation
The TYCO Model WS Specic
Application Window Sprinklers must
be installed in accordance with this
section.
General Instructions
Do not install any bulb-type sprinkler if
the bulb is cracked or there is a loss
of liquid from the bulb. With the sprin-
kler held horizontally, a small air bubble
should be present. The diameter of the
air bubble is approximately 1/16 in. (1,6
mm).
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 may distort the sprinkler inlet
with consequent leakage or impairment
of the sprinkler.
Step 1. Install the pendent vertical side-
wall sprinkler only in the pendent posi-
tion with the center-line of the sprinkler
parallel to the glass surface. Orient the
sprinkler so that the direction of ow
indicated on the sprinkler deector is
facing the window.
Step 2. Install the horizontal side-
wall sprinkler only in the horizontal
position with the center-line of the
sprinkler perpendicular to the glass
surface. Orient the sprinkler so that the
word “Top” indicated on the sprinkler
deector is facing the top of window
frame.
Step 3. With pipe-thread sealant
applied to the pipe threads, hand-
tighten the sprinkler into the sprinkler
tting.
Step 4. With reference to Figures 1 or
2, apply End A of W-Type 20 Sprinkler
Wrench only (Figure 4) to the sprinkler
wrench ats and tighten the sprinkler
into the sprinkler tting.

be maintained and serviced in accor-
dance with this section.
Before closing a re protection system
main control valve for maintenance
work on the re protection system
that it controls, obtain permission to
shut down the affected re protection
systems from the proper authorities
and notify all personnel who may be
affected by this action.
Sprinklers which are found to be
leaking or exhibiting visible signs of
corrosion must be replaced.
Automatic sprinklers must never be
painted, plated, coated, or other-
wise altered after leaving the factory.
Modied sprinklers must be replaced.
Sprinklers that have been exposed to
corrosive products of combustion, but
have not operated, should be replaced
if they cannot be completely cleaned
by wiping the sprinkler with a cloth or
by brushing it with a soft bristle brush.
Care must be exercised to avoid
damage to the sprinklers - before,
during, and after installation. Sprinklers
damaged by dropping, striking, wrench
twist/slippage, or the like, must be
replaced. Also, replace any sprinkler
that has a cracked bulb or that has lost
liquid from its bulb. (Ref. Installation
Section.)
The owner is responsible for the
inspection, testing, and maintenance of
their re protection system and devices
in compliance with this document, as
