kENTERLlNE OF COVERAGE AREA
PLAN VIEW
1. For a given position within the coverage area, ceiling mounted obstructions must not hang
below the elevation dimension given in the graph.
2. Elevation dimensions are perpendicular to the plane of the Deflector Hat (ref. Fig. A), where
positive (+) dimensions are above the plane of the Deflector Hat and negative (-)
dimensions are below. (Reference: the Deflector Hat is 7/16" (11,l mm) above the
sprinkler centerline of waterway.)

SUCH AS HEATING OR AIR CONDITIONING DIFFUSERS, OVERHANGS,
AND LIGHT FIXTURES
Strut is silicone bronze per ASTM B96
(C65500), and the Deflector is brass
per ASTM 836 (C22000). The Hook is
phosphor bronze per ASTM B159
(C51000), the two halves of the Link
Assembly are nickel, the Ejection
Spring is lnconel 600 wire per ASTM
B166, and the Button is brass per
ASTM 836 (C22000). The Gasket ma-
terial is Teflonf, and the Spring Plate
is an lnconel disc spring.
The Link Assembly has a thin, black,
resin type coating which will protect
the Link Assembly from deterioration
which could otherwise be caused by
normal atmospheres. The coating is
not intended to provide protection
against attack by corrosive media.
Escutcheon Plates:
Figures B-l and B-2, as applicable,
provide wall mounting dimensions for
the FR-1 Sprinkler and illustrate the
use of a standard one-piece escutch-
eon plate like that described in Tech-
nical Data Sheet TD805.
The FR-1 Sprinklers may be installed
with a split type escutcheon plate like
that described in TD815. The split type
plate is suitable for use with plastic
pipe fire protection systems when it is
installed in accordance with the in-
structions given in TD815.
NOTES
The standard type escutcheon
plate like that shown in Technical
Data Sheet TD805 can NOT be
used to hold the FR-1 in position.
The FR-1 must be secured in posi-
tion by firmly fastening the
sprinkler system piping to the
dwelling structure.
If
the FR-1 is
not properly secured in position,
reaction forces resulting' from
sprinkler operation could alter
its orientation and water distri-
bution pattern.
Only use escutcheon plates that
will provide a deflector-to-mount-
ing surface distance within the
range specified in Figure B-l or
B-2, as applicable.
Only use escutcheon plates which
consist of metallic materials that
will not deform or dislodge at a
temperature
of
less
than
12OO"Fl649"C andlor which have
been listed by Underwriters Labo-
ratories
Inc. for fire protection
service.
- extended coverage) or EC (ex-
tended coverage) applications, the
17/32 inch (20 mm) orifice, Model FR-1
Horizontal Sidewall Sprinklers must
only be installed and utilized in Light
Hazard Occupancies, under smooth
ceilings and in accordance with the
criteria given in Table A-l or A-2, as
applicable. The nominal wetting pat-
terns are illustrated in Figure D for the
minimum flows required for typical
coverage areas.
NOTE
For coverage area dimensions
less than or between those indi-
cated in Table A-l or A-2, it is
necessary to use the minimum re-
quired flow for the next highest
width (W) and length (L)
for
which installation criteria are
stated.
Ceiling mounted obstructions such as
heating or air conditioning diffusers,
overhangs, and light fixtures must be
located above an elevation, as shown
in Figure F, where they will not inter-
fere with the proper distribution of
water by the sprinkler.
NOTE
The FR-1 Sprinklers must NOT be
used with beams, joists, or ducts
located within the sprinkler cov-
erage area. They may be located
along the boundaries separating
adjacent sprinkler coverage
areas.
