Tyco EC-8 Series Quick Start Manual

Series EC-8 — 8.0 K-factor
Extended Coverage (Light Hazard)
Pendent and Recessed Pendent Sprinklers
General
Description
The Series EC-8 Extended Cover-
age Pendent Sprinklers are decora-
tive glass bulb sprinklers designed
for use in light hazard occupancies.
They are intended for use in automatic
sprinkler systems designed in accor-
dance with standard installation rules
(e.g., NFPA 13) for a maximum cover-
age area of 400 ft 2 (37,2 m
pared to the maximum coverage area
of 225 ft 2 (20,6 m 2 ) for standard cov-
erage sprinklers used in light hazard
occupancies.
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
provides up to 1/2 inch (12,7 mm) of
total adjustment from the flush pen-
dent position, whereas, the Style 40
provides 3/4 inch (19,1 mm) of verti-
cal adjustment from the flush pendent
position. The adjustment provided by
the Recessed Escutcheons reduces
the accuracy 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-
tant coated sprinklers have passed
the standard corrosion tests of the ap-
plicable approval agencies, the test-
ing is not representative of all possible
IMPORTANT
Always refer to Technical Data
Sheet TFP700 for the "INSTALLER
WARNING" that provides cau-
tions with respect to handling
and installation of sprinkler sys-
tems and components. Improp-
er handling and installation can
permanently damage
kler system or its components
and cause the sprinkler to fail
to operate in a fire situation or cause
it to operate prematurely.

corrosive atmospheres. Consequent-
ly, it is recommended that the end
user be consulted with respect to the
suitability of these corrosion resistant
coatings for any given corrosive envi-
ronment. The effects of ambient tem-
perature, concentration of chemicals,
and gas/chemical velocity, should be
considered, as a minimum, along with
the corrosive nature of the chemical to
which the sprinklers will be exposed.
