Description
The Central Model K17-231
matic Sprinkler has been tested and
listed for storage occupancies. Full-scale
fire testing of high challenge fires in
storage occupancies using low required
operating pressures was conducted and
was successful.
The fire tests results show pressures as
low as 7 psi can be used with the
(0.5 bar)
TM
Central K17-231 . This results in very
low pressure requirements that can save
cost by reducing branch line sizes,
increasing the spacing, eliminating
booster pumps, and upgrading existing
densities.
TM
The Model K17-231 is used with the
area density curves of NFPA 231and
231C. It is essentially a Standard Spray
Sprinkler with a 17.5
(252.4 metric)
Factor. The larger K-Factor allows the
pressure to be reduced when compared
to ELO, LO, or standard orifice sprin-
klers. This reduction in pressure results
in cost savings on the overall system.
TM
The K17-231 differs from the ULTRA
K-17 TM by its brass deflector, the markings
on the deflector, and the K-Factor.
