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.

General
Description
The EC-8C 8.0 K-factor Special Appli-
cation, Quick Response Pendent and
Recessed Pendent Sprinklers are UL
Listed for Light Hazard Occupancies
and were specifically designed for use
in long, narrow spaces such as corri-
dors or hallways with a maximum cov-
erage area of 28 ft by 10 ft (8,5 m x 3,1
m). Fewer sprinklers and lower system
pressure demands are required as
compared to the traditional extended
coverage sprinklers. Series EC-8C
sprinklers are intended for use in auto-
matic sprinkler systems designed in
accordance per NFPA 13.
The recessed version of the Series
EC-8C, Pendent Sprinkler intended
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 in. (12,7 mm) of total adjust-
ment from the flush pendent posi-
tion, whereas, the Style 40 provides
3/4 in. (19,1 mm) of vertical adjustment
from the flush pendent position. The
adjustment provided by the Recessed
Escutcheons 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 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
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.
NOTICE
The Series EC-8C Pendent Sprinklers
described herein must be installed
and maintained in compliance 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 performance
of these devices.
The owner is responsible for main-
taining their fire protection system
and devices in proper operating con-
dition. Contact the installing contrac-
tor or product manufacturer with any
questions.
