Tyco EC-8 Series User manual

General
Description
The Series EC-8 Extended Coverage
Pendent Sprinklers are decorative
glass bulb sprinklers designed for use
in light hazard occupancies. They are
intended for use in automatic sprinkler
systems designed in accordance with
standard installation rules (e.g., NFPA
13) for a maximum coverage area of
400 ft2(37,2 m2), as compared to the
maximum coverage area of 225 ft2
(20,6 m2) for standard coverage sprin-
klersusedinlighthazardoccupancies.
The recessed version of the EC-8, in-
tended for use in areas with a finished
ceiling, uses either the two-piece Style
30 or 40 Recessed Escutcheon. The
Style 30 Recessed Escutcheon pro-
vides up to 1/2 inch (12,7 mm) of total
adjustment from the flush pendent po-
sition, whereas, the Style 40 provides
3/4 inch (19,1 mm) of vertical adjust-
ment from the flush pendent position.
The adjustment provided by the Re-
cessed Escutcheons reduces the ac-
curacy to which the fixed pipe drops to
the sprinklers must be cut.
Corrosion resistant coatings, where
applicable, are utilized to extend the
life of copper alloy sprinklers beyond
that which would otherwise be ob-
tained when exposed to corrosive at-
mospheres. Although corrosion resis-
tantcoatedsprinklershave passed the
standard corrosion tests of the appli-
cable approval agencies, the testing is
not representative of all possible cor-
rosive atmospheres. Consequently, it
is recommended that the end user be
consulted with respect tothe suitability
of these corrosion resistant coatings
for any given corrosive environment.
The effects of ambient temperature,
concentration of chemicals, and
gas/chemical velocity, should be con-
sidered, as a minimum, along with the
corrosive nature of the chemical to
which the sprinklers will be exposed.
WARNINGS
The Series EC-8 Extended Coverage
Sprinklers described herein must be
installed and maintained in compli-
ance 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 per-
formance of these devices.
The owner is responsible for maintain-
ing their fire protection system and de-
vices in proper operating condition.
The installing contractor or sprinkler
manufacturer should be contacted
with any questions.

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

Operation
The glass bulb contains a fluid that
expands when exposed to heat. When
the rated temperature is reached, the
fluid expands sufficiently to shatter the
glass bulb, allowing the sprinkler to
activate and flow water.

Installation
The Series EC-8 Sprinklers must be
installed in accordance with the follow-
ing 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).
A leak tight 3/4 inch NPTsprinkler joint
should be obtained with a torque of 10
to 20 ft.lbs. (13,4 to 26,8 Nm). A maxi-
mum 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 leak-
age or impairment of the sprinkler.
Do not attempt to compensate for in-
sufficientadjustmentofanEscutcheon
Plate by under- or over-tightening the
Sprinkler. Readjust the position of the
sprinkler fitting to suit.
Step 1. The sprinkler must be installed
withthedeflectorparalleltothemount-
ing surface. Pendent sprinklers must
be installed in the pendent position.
Step 2. After installing the Style 30 or
40 mounting plate (or other escutch-
eon, 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 sprin-
klers using only the W-Type 3 (End A)
Sprinkler Wrench. Wrench tighten the
recessed pendent sprinklers using
only the W-Type 23 Sprinkler Wrench.
The wrench recess of the applicable
sprinkler wrench (Ref. Figure 4 and 5)
is to be applied to the sprinkler wrench
flats (Ref. Figure 1).

Care and
Maintenance
The Series EC-8 Sprinklers must be
maintained and serviced in accord-
ance with the following instructions:
NOTE
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 systems
must be obtained from the proper
authorities and all personnel who may
be affected by this action must be no-
tified.
Sprinklers that are found to be leaking
or exhibiting visible signs of corrosion
must be replaced.
Automatic sprinklers must never be
painted, plated, coated, or otherwise
altered after leaving the factory. Modi-
fied sprinklers must be replaced.

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 dam-
age to the sprinklers - before, during,
and after installation. Sprinklers dam-
aged by dropping, striking, wrench
twist/slippage, or the like, must be re-
placed.Also,replaceanysprinklerthat
has a cracked bulb or that has lost
liquid from its bulb. (Ref. Installation
Section).
Frequent visual inspections are rec-
ommendedtobeinitiallyperformedfor
corrosion resistant coated sprinklers,
after the installation has been com-
pleted, to verify theintegrity of the cor-
rosion resistant coating. Thereafter,
annual inspections per NFPA 25
should suffice; however, instead of in-
specting from the floor level, a random
sampling of close-up visual inspec-
tions should be made, so as to better
determine the exact sprinkler condi-
tion and the long term integrity of the
corrosion resistant coating, as it may
be affected by the corrosive conditions
present.
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 in-
stalling contractor or sprinkler manu-
facturer should be contacted relative
to any questions.
It is recommended that automatic
sprinkler systems be inspected,
tested, and maintained by a qualified
Inspection Service in accordance with
local requirements and/or national
codes.
