Series LFII Residential
Flush Pendent Sprinklers
4.2 K-factor
General
Description
The Series LFII (TY2284) Residential
Flush Pendent Sprinklers are decora-
tive, fast response, fusible solder
sprinklers designed for use in residen-
tial occupancies such as homes,
apartments, dormitories, and hotels.
When aesthetics is the major consid-
eration, the Series LFII (TY2284)
should be the first choice.
The Series LFII are to be used in wet
pipe residential sprinkler systems for
one- and two-family dwellings and
manufactured homes per NFPA 13D;
wet pipe residential sprinkler systems
for residential occupancies up to and
including four stories in height per
NFPA 13R; or, wet pipe sprinkler sys-
tems for the residential portions of any
occupancy per NFPA 13.
The Series LFII (TY2284) has a 4.2
(60,5) K-factor that provides the re-
quired residential flow rates at reduced
pressures, enabling smaller pipe sizes
and water supply requirements.
The flush design of the Series LFII
(TY2284) features a separable es-
cutcheon providing 3/8 inch (9,5 mm)
vertical adjustment. This adjustment
reduces the accuracy to which the pipe
drops to the sprinklers must be cut to
help assure a perfect fit installation.
IMPORTANT
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 in-
stallation 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.

The Series LFII (TY2284) has been
designed with heat sensitivity and
water distribution characteristics
proven to help in the control of residen-
tial fires and to improve the chance for
occupants to escape or be evacuated.

The Series LFII (TY2284) Residential
Flush Pendent Sprinklers described

tained in compliance with this docu-
ment, as well as with the applicable

Operation
The sprinkler assembly contains a
small fusible solder element. When ex-
posed to sufficient heat from a fire, the
solder melts and enables the internal
components of the sprinkler to fall
away. At this point the sprinkler acti-
vates with the deflector dropping into
its operated position (Reference Fig-
ure 1C), permitting water to flow.
