Description
The TYCO RAPID RESPONSE Series
LFII
Residential
Flush
Sprinklers (TY2284) are decorative,
fast response, fusible solder sprinklers
designed for use in residential occu-
pancies such as homes, apart-
ments, dormitories, and hotels. When
aesthetics is the major consideration,
the Series LFII Residential Sprinklers
(TY2284) should be the first choice.
The Series LFII Residential Sprinklers
are intended for use in the following
scenarios:
• wet and dry pipe residential sprinkler
systems for one- and two-family
dwellings and mobile homes per
NFPA 13D
• wet and dry pipe residential sprinkler
systems for residential occupancies
up to and including four stories in
height per NFPA 13R
• wet and dry pipe sprinkler systems
for the residential portions of any
occupancy per NFPA 13

Dry Pipe System Application
The Series LFII Residential Flush
Pendent
Pendent Sprinklers offers a laboratory
approved option for designing dry pipe
residential sprinkler systems, whereas,
most residential sprinklers are labora-
tory approved for wet systems only.
Through extensive testing, it has been
determined that the number of design
sprinklers (hydraulic design area)
for the Series LFII Residential Flush
Pendent Sprinklers (TY2284) need
not be increased over the number of
design sprinklers (hydraulic design
area) as specified for wet pipe sprinkler
systems, as is customary for density/
area sprinkler systems designed per
NFPA 13.
Consequently,
Residential Sprinklers (TY2284) offer
the features of non-water filled pipe in
addition to not having to increase the
number of design sprinklers (hydraulic
design area) for systems designed
to NFPA 13, 13D, or 13R. Non-water
filled pipe will permit options for areas
sensitive to freezing.
