Series EC-8 — 8.0 K-factor
Extended Coverage (Light Hazard)
Pendent and Recessed Pendent Sprinklers
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 ft 2 (37,2 m 2 ), as compared to the
maximum coverage area of 225 ft
(20,6 m 2 ) for standard coverage sprin-
klers used in light hazard occupancies.
The recessed version of the EC-8,
intended for use in areas with a fin-
ished ceiling, uses either the two-piece
Style 30 or 40 Recessed Escutch-
eon. The Style 30 Recessed Escutch-
eon provides up to 1/2 in. (12,7 mm)
of total adjustment from the flush
pendent position, whereas, the Style
40 provides 3/4 in. (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 obtained
when exposed to corrosive atmo-
spheres. Although corrosion resistant
coated sprinklers have passed the
standard corrosion tests of the appli-
cable approval agencies, the testing is

Refer to Technical Data Sheet
TFP2300 for warnings pertaining to
regulatory and health information.
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
installation 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.

not representative of all possible cor-
rosive atmospheres. Consequently, it
is recommended that the end user be
consulted with respect to the suitabil-
ity of these corrosion resistant coatings
for any given corrosive environment.
The effects of ambient temperature,
concentration of chemicals, and gas/
chemical velocity, should be consid-
ered, as a minimum, along with the cor-
rosive nature of the chemical to which
the sprinklers will be exposed.
