ated with the F687 Sprinklers have
been proven to help in the control of
residential type fires and, therefore, to
improve the chance for occupants to
escape or be evacuated.
Fire sprinkler systems are not a substi-
tute for intelligent fire safety aware-
ness or construction materials and
practices required by building codes.
APPROVALS AND STANDARDS
The 5.8 K-factor, Model F687 Residen-
tial Horizontal and Recessed Horizon-
tal Sidewall Sprinklers are listed by
Underwriters Laboratories Inc. and
Underwriters’ Laboratories of Canada.
The listings only apply to the sprinkler
finishes and service conditions indi-
cated in the General Technical Data
and Residential Design Criteria sec-
tions.
The 5.8 K-factor, Model F687 Residen-
tial Horizontal and Recessed Horizon-
tal Sidewall Sprinklers are also ap-
proved by the Scientific Ser vices
Laboratory (Australia), as well as ac-
cepted by the City of New York under
MEA 39-92-M.
Any questions concerning an interpre-
tation of NFPA 13, 13D, or 13R sprin-
kler system design/installation stand-
ards, as well as requests for system
design/installation standards not pres-
ently covered by NFPA 13, 13D, or
13R, should be addressed to the:
Secretary, Standards Council
National Fire Protection Association

WARNINGS
The Model F687 Residential Hori-
zontal and Recessed Horizontal
Sidewall Sprinklers described
herein must be installed and
maintained in compliance with
this document, as well as with the
applicable standards of the Na-
tional Fire Protection Associa-
tion, in addition to the standards
of any other authorities having
jurisdiction. Failure to do so may
impair the integrity of these de-
vices.
Because of the above cited stipu-
lations and the varied nature of
residential type architecture,
there may be some compartment
designs which cannot be fully
sprinklered in accordance with
the recommendations of NFPA 13,
13D, or 13R. In the event of this
condition, consult the authorities
having jurisdiction for guidance
and approval.
It is the responsibility of an in-
stalling contractor to provide a
copy of this document to the
owner or his representative and,
in turn, it is the obligation of the
owner to provide a copy of this
document to a succeeding owner.
The owner is responsible for
maintaining their fire protection
system and devices in proper op-
erating condition. The installing
contractor or sprinkler manufac-
turer should be contacted relative
to any questions.

NOTES:
(a) Wet pipe fire sprinkler systems in the residential portions of any occupancy per NFPA 13, in one- and two- family dwellings and mobile
homes per NFPA 13D, or residential occupancies per NFPA 13R.
(b) For coverage area dimensions less than or between those indicated, it is necessary to use the minimum required flow for the next highest
coverage area for which hydraulic design criteria are stated.
(c) Requirement is based on minimum flow in GPM from each sprinkler. The indicated residual pressures are based on the nominal K-factor.
(d) Refer to Hydraulic Design Criteria under Residential Design Criteria Section for details.
(e) To meet this requirement, the centerline of the waterway (Ref. Fig. A) must be installed between 4-3/8 and 6-3/8 inches below the ceiling.
(f) To meet this requirement, the centerline of the waterway (Ref. Fig. A) must be installed between 4-3/8 and 12-3/8 inches below the ceiling.
