Tyco Fire Product CENTRAL K17-231 User manual

Operation: The glass bulb contains a
fluid which expands when exposed to
heat. When the rated temperature is
reached, the fluid expands sufficiently to
shatter the glass bulb, which then allows
the sprinkler to activate & flow water.
WARNING
The K17-231 Upright and Pendent
Sprinklers described herein must be
installed and maintained in compliance
with this document, as well as with the
applicable standards of the National Fire
Protection Association, in addition to the
standards of any other authorities
having jurisdiction. Failure to do so may
impair the integrity of these devices.
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
relative to any questions.

General
Description
The Central Model K17-231, 16.8
K-factor, Standard Response, Standard
Coverage, Pendent & Upright Sprinklers
are automatic sprinklers of the frangible
bulb type. They are "standard response
- spray sprinklers" which produce a
hemispherical water distribution pattern
below the deflector.
The Model K17-231 Sprinklers are
intended for use in fire sprinkler
systems designed in accordance with
the standard installation rules recog-
nized by the applicable Listing or
Approval agency (e.g., UL Listing is
based on the requirements of the
National Fire Protection Association).
Also, when acceptable to the Authority
Having Jurisdiction, they may be used
with a "Reduced Design Area" as
indicated in Table 2.
The 16.8 K-factor Model K17-231
Sprinklers were subjected to full scale,
high-piled storage, fire tests to qualify
their use in lieu of 5.6 or 8.0 K-factor
standard spray sprinklers for the
protection of high-piled storage.
Higher flow rates can be achieved at
much lower presures with the Model
K17-231 Sprinklers; making their use
highly advantageous in high density
applications, such as the protection of
high-piled storage.
The use of the 16.8 K-factor Model
K17-231Sprinkler also has the advan-
tage of having a specific application
listing, which in some cases can
subsequently reduce the design area
and the overall water demand of a
sprinkler system. Refer to Table 2 for
details.

Physical Characteristics
The Model K17-231 Upright & Pendent
Sprinklers utilize a dezincification
resistant (DZR) bronze frame and a 5
mm bulb. The two-piece button
assembly is brass and copper. The
sprinkler frame orifice is sealed with a
gasketed spring plate (Belleville Seal)
consisting of a beryllium nickel disc
spring that is sealed on both its inside
and outside edges with a TeflonTM
gasket. The compression screw is
bronze, & the deflector is brass.

Approved for use in accordance with
the FM Loss Prevention Data Sheets.
These "Control Mode Area/Density
Sprinklers" are approved with a
minimum residual (flowing) pressure of
7 psi (0,48 bar).
These sprinklers can be used with any
metalic flush or extended escutcheon,
provided the maximum ceiling to top of
sprinkler deflector dimension specified
in NFPA 13 is maintained. These
sprinklers are not listed or approved for

Table 1 - Laboratory Listings and Approvals
(16.8 K-factor Sprinklers 3/4" NPT)
The Model K17-231 Upright & Pendent
Sprinklers
must be installed in accor-
dance with the following instructions.
NOTES
Do not install any bulb type sprinkler if
the bulb is cracked or there is a loss of
liquid from the bulb. With the sprinkler
held horizontally, a small air bubble
should be present. The diameter of the
air bubble is approximately 1/16 inch
(1,6 mm) for the 155
° F/68 ° C to 3/32
inch (2,4 mm) for the 286
° F/141 ° C
rating.
A leak tight 3/4 inch NPT sprinkler joint
should be obtained with a torque of 10
to 20 ft.lbs. (13,4 to 26,8 Nm). A

Installation
maximum of 30 ft.lbs. (40.7 Nm) of
torque is to be used to install 3/4 inch
NPT sprinklers. Higher levels of torque
may distort the sprinkler inlet with
consequent leakage or impairment of
the sprinkler.
Step 1. Upright sprinklers must be
installed only in the upright position and
pendent sprinklers must be installed
only in the pendent position. The
deflector is to be parallel to the ceiling,
roof, or mounting surface, as applicable.
Step 2. With pipe thread sealant applied
to the pipe threads, hand tighten the
sprinkler into the sprinkler fitting.
Step 3. Tighten the sprinkler into the
sprinkler fitting using only the W-Type 8
Sprinkler Wrench (Ref. Figure 4), With
reference to Figure 1 & 2, the W-Type 8
Sprinkler Wrench is to be applied to the
wrench flats only.

NOTES
Before closing a fire protection system
main control valve for maintenance
work on the fire protection system it
controls, permission to shut down the
affected fire protection systems must be
obtained from the proper authorities.
All personnel who may be affected by
this action must be notified.
Sprinklers which are found to be
leaking or exhibiting visible signs of
corrosion must be replaced.
Automatic sprinklers must never be
shipped or stored where their tempera-
tures will exceed 100°F/38°C and they
must never be painted, plated, coated
or otherwise altered after leaving the
factory. Modified 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 - 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 fire protection system and devices
in compliance with this document, as
well as with the applicable standards of
the National Fire Protection Association
