5.6 K-factor Horizontal Sidewall, NFPA 13 Optimized
Wet Pipe Systems
General
Description
The TYCO RAPID RESPONSE Series
LFII (TY3334) Residential Horizontal
Sidewall Sprinklers are decorative,
fast response, frangible bulb sprin-
klers designed for use in residential
occupancies such as homes, apart-
ments, dormitories, and hotels. When
enhanced flow characteristics for resi-
dential portions of any occupancy per
NFPA 13 is the major consideration, the
Series LFII (TY3334) should be the first
choice.
When higher flow demands are
required for residential sprinklers used
in an NFPA 13 design, the large 5.6
K-factor of the Series LFII (TY3334) is
an attractive choice. Although mostly
intended where residential sprinklers
are to be used in an NFPA 13 design,
the Series LFII (TY3334) can also be
used in wet pipe residential sprin-
kler systems for one- and two-family
dwellings and mobile homes per NFPA
13D, and wet pipe residential sprinkler
systems for residential occupancies up
to and including four stories in height
per NFPA 13R.
The recessed version of the Series
LFII (TY3334) is intended for use in
areas with finished walls. It employs
a two-piece Style 20 Recessed
Escutcheon. The Recessed Escutch-
eon provides 1/4 inch (6,4 mm) of
recessed adjustment or up to 1/2 inch
(12,7 mm) of total adjustment from the
flush mounting surface position. The
adjustment provided by the Recessed
