Tyco EC-5 Series User manual

General
Description
The Series EC-5 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-
klers used in light hazard occupancies.
The recessed version of the EC-5, in-
tended for use in areas with a finished
ceiling, uses the two-piece Style 50
Recessed Escutcheon. The Style 50
Recessed Escutcheon provides up to
3/8 inch (9,5 mm) of total adjustment
from the flush pendent position. The
adjustment provided by the Recessed
Escutcheon reduces the accuracy to
which the fixed pipe drops to the sprin-
klers 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-
tant coated sprinklers have 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 to the 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-5 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.

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 com-
ponents. Improper handling and in-
stallation 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.

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.
Design
Criteria
The Series EC-5 Extended Coverage
Pendent Sprinklers must only be in-
stalled in accordance with the applica-
ble UL and C-UL Listing or FM Ap-
proval requirements as indicated
below. Only the Style 50 Recessed Es-
cutcheon is to be used for recessed
installation, as applicable (Ref. Table
A, B, and C).
ULandC-ULListing
Requirements
1. The Series EC-5 Sprinklers may be

in Table D, based on maintaining the
minimum specified flow rate as a
function of coverage area and haz-
ard group for all of the sprinklers in
the design area.
2. With respect to heat sensitivity, the
Series EC-5 Sprinklers are permit-
ted to be used with unobstructed

FM Approval
Requirements
The Series EC-5 Extended Coverage
Sprinklers are to be installed in ac-
cordance with the applicable Factory
Mutual Loss Prevention Data Sheet.
Information provided in the FM Loss
Prevention Data Sheets relate to, but
are not limited to, hydraulic design,
ceiling slope and obstructions, mini-
mum and maximum allowable spacing,
and deflector-to-ceiling distance.
Installation
The Series EC-5 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 1/2 inch NPT sprinkler joint
should be obtained with a torque of 7
to 14 ft.lbs. (9,5 to 19,0 Nm). A maxi-
mum of 21 ft.lbs. (28,5 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-
sufficient adjustment in an Escutcheon
Plate by under- or over-tightening the
Sprinkler. Readjust the position of the
sprinkler fitting to suit.
Step 1. The sprinkler must be installed
with the deflector parallel to the mount-
ing surface. Pendent sprinklers must
be installed in the pendent position.
Step 2. After installing the Style 50
mounting plate (or other escutcheon,
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 6 (End A)
Sprinkler Wrench. Wrench tighten the
recessed pendent sprinklers using
only the W-Type 7 Sprinkler Wrench.
The wrench recess of the applicable
sprinkler wrench (Ref. Figure 3 and 4)
is to be applied to the sprinkler wrench
flats (Ref. Figure 1).

Care and
Maintenance
The Series EC-5 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 authori-
ties and all personnel who may be
affected by this action must be notified.
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.
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 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, replace any sprinkler that
has a cracked bulb or that has lost
liquid from its bulb. (Ref. Installation
Section).
Frequent visual inspections are rec-
ommended to be initially performed for
corrosion resistant coated sprinklers,
after the installation has been com-
pleted, to verify the integrity 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.
