Tyco Fire Product CENTRAL K11 ECLH User manual

General
Description
The Central Model K11 ECLH, 11.2
K-Factor, Quick Response, Extended
Coverage Light Hazard (ECLH) Pen-
dent and Recessed Pendent Sprin-
klers are decorative glass bulb sprin-
klers designed for use in light hazard
occupancies such as churches, hos-
pitals, offices, and restaurants.
They are intended for use in automat-
ic sprinkler systems designed in ac-
cordance with standard installation
rules (e.g., NFPA 13) for the protec-
tion of light hazards up to a maxi-
mum coverage area of 400 ft2(37,2
m2), as compared to the maximum
coverage area of 225 ft2(20,9 m2)
for standard coverage sprinklers.
The recessed version of the Models
K11 ECLH Sprinklers using a two-
piece Series 4221 Recessed Es-
cutcheon provides up to 1/2 inch
(12,7 mm) of total adjustment from
the flush pendent position. The ad-
justment provided by the Recessed
Escutcheon reduces the accuracy to
which the fixed pipe drops to the
sprinklers must be cut.
Operation. The glass bulb contains
a fluid which expands when exposed
to heat. When the rated temperature
is reached, the fluid expands suffi-
ciently to shatter the glass bulb,
which then allows the sprinkler to ac-
tivate and flow water.
WARNINGS
The Model K11 ECLH Sprinklers de-
scribed herein must be installed and
maintained in compliance with this
document, as well as with the appli-
cable standards of the National Fire
Protection Association, in addition to
the standards of any other authori-
ties having jurisdiction. Failure to do
so may impair the integrity of these
devices.
The owner is responsible for main-
taining their fire protection system
and devices in proper operating con-
dition. The installing contractor or
sprinkler manufacturer should be
contacted relative to any questions.

Installation
The Model K11 ECLH Sprinklers
must be installed in accordance 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 di-
ameter of the air bubble is approxi-
mately 1/16 inch (1,6 mm) for the
135°F/57°C to 200°F/93°C tempera-
ture ratings.
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 maximum of 30 ft.lbs.
(40,7 Nm) of torque is to be used to
install sprinklers. Higher levels of
torque may distort the sprinkler inlet
with consequent leakage or impair-
ment of the sprinkler.
Do not attempt to compensate for in-
sufficient adjustment in an Escutch-
eon Plate by under- or over-tighten-
ing the Sprinkler. Readjust the
position of the sprinkler fitting to suit.
Step 1. Model K11 ECLH Sprinklers
must be installed in the pendent posi-
tion and with the deflector parallel to
the mounting surface.
Step 2. After installing the Series
4221 mounting plate (or other es-
cutcheon, as applicable) over the
sprinkler pipe threads and with pipe
thread sealant applied to the pipe
threads, hand tighten the sprinkler
into the sprinkler fitting.
Step 3. Wrench tighten pendent
sprinklers using only the W-Type 3
(End B) Sprinkler Wrench. Wrench
tighten the recessed pendent sprin-
klers using only the W-Type 5 Sprin-
kler Wrench. The wrench recess of
the applicable sprinkler wrench
(Ref. Figure 3 and 4) is to be applied
to the sprinkler wrench flats (Ref. Fig-
ure 1).
Care &
Maintenance
The Model K11 ECLH Sprinklers
must be maintained and serviced in
accordance with the following instruc-
tions:
NOTES
Absence of an escutcheon, which is
used to cover a clearance hole, may
delay the time to operation in a fire
situation.
Before closing a fire protection sys-
tem main control valve for mainte-
nance work on the fire protection sys-
tem which it controls, permission to
shut down the affected fire protec-
tion systems must be obtained from
the proper authorities and all person-
nel who may be affected by this ac-
tion 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 tem-
perature will exceed 100°F/38°C and
they must never be painted, plated,
coated, or otherwise altered after
leaving the factory. Modified sprin-
klers must be replaced. Sprinklers
that have been exposed to corrosive
products of combustion, but have not
operated, should 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/slip-
page, 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 Sec-
tion).
The owner is responsible for the in-
spection, testing, and maintenance
of their fire 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 (e.g., NFPA 25), in
addition to the standards of any
other authorities having jurisdiction.
The installing contractor or sprinkler
manufacturer should be contacted
relative to any questions.
It is recommended that automatic
sprinkler systems be inspected,
tested, and maintained by a qualified
Inspection Service.
