The Series LFII Dry Type Residential
Horizontal Sidewall Sprinklers are typ-
ically used where sprinklers and/or a
portion of the connecting piping are
exposed to freezing temperatures (for
example, horizontal sprinkler supplied
from wet systems into unheated areas).
The Series LFII Dry Type Residen-
tial Horizontal Sidewall Sprinklers are
intended for use in Residential Sprin-
kler systems for one- and two-family
dwellings and mobile homes per NFPA
13D; residential sprinkler systems for
residential occupancies up to and
including four stories in height per
NFPA 13R; or, sprinkler systems for the
residential portions of any occupancy
per NFPA 13.
The recessed version is intended
for use in areas with finished walls.
It employs a two-piece Style 20
Recessed Escutcheon. The Recessed
Escutcheon provides 1/4 in. (6,4 mm)
of recessed adjustment or up to 1/2 in.
(12,7 mm) of total adjustment from the
flush mounting surface position. The
design of this escutcheon provides a
level of flexibility in adjusting sprinkler
supply connections.
The Series LFII Dry Type Residential
Horizontal Sidewall Sprinklers have
been designed with heat sensitivity and
water characteristics proven to help in
the control of residential fires and to
improve the chance for occupants to
escape or be evacuated.
Corrosion-resistant coatings, where
applicable, are utilized to extend the life
of copper alloy sprinklers beyond that
which would otherwise be obtained
when exposed to corrosive atmo-
spheres. Although corrosion-resistant
coated sprinklers have passed the
standard corrosion tests of the appli-
cable Approval agencies, the testing is
not representative of all possible cor-
rosive atmospheres. Consequently,
it is recommended that the end user
be consulted with respect to the suit-
ability of these coatings for any given
corrosive environment. The effects of

ambient temperature, concentration of

along with the corrosive nature of the
chemical to which the sprinklers will be
exposed.
