General
Description
The Central Models K11 & K14
ECOH, 11.2 and 14.0 K-Factor,
Standard Response, Extended Cov-
erage Ordinary Hazard (ECOH) Pen-
dent, Recessed Pendent, and Up-
right Sprinklers are decorative glass
bulb sprinklers designed for use in
ordinary hazard occupancies such
as showrooms, retail stores, and
light manufacturing.
They are intended for use in automat-
ic sprinkler systems designed in ac-
cordance with standard installation
rules (e.g., NFPA 13) for the protec-
tion of ordinary hazards up to a maxi-
mum coverage area of 256 ft

) for the K14, as compared to the
maximum coverage area of 130 ft
2
(12,1 m
) for standard coverage
sprinklers.
The Models K11 & K14 ECOH Sprin-
klers feature a UL and C-UL Listing
that permits their use with unob-
structed or non-combustible ob-
structed ceiling construction as de-
fined and permitted by NFPA 13.
The Models K11 & K14 ECOH Sprin-
klers have been fire tested to com-
pare their performance to that of
standard spray sprinklers installed at
standard spacings (i.e. 15 feet maxi-
mum on center spacing and 130 sq.
ft. maximum coverage area for ordi-
nary hazard). These tests have
shown that the protection provided
by these ECOH Sprinklers is equal
to or more effective than standard
spray sprinklers.
The recessed version of the Models
K11 & K14 ECOH Sprinklers using a
two-piece Series 4211 Recessed Es-
cutcheon provides up to 3/4 inch
(19,1 mm) of total adjustment from
the flush pendent position. The ad-
justment provided by the Recessed
K11 & K14 ECOH
Escutcheon reduces the accuracy to
which the fixed pipe drops to the
sprinklers must be cut.
Operation. The glass bulb contains
a fluid which expands when exposed
to heat. When the rated temperature
is reached, the fluid expands suffi-
ciently to shatter the glass bulb,
which then allows the sprinkler to ac-
tivate and flow water.

klers described herein must be in-

ance with this document, as well as
