APPROVALS AND STANDARDS
Laboratory listings and approvals for
the 11.2 and 14.0 K-Factor, Model
F895 Extended Coverage Ordinary
Hazard (ECOH) Pendent, Recessed
Pendent, and Upright Sprinklers are
given in Table A.
The laboratory listings and approvals
only apply to the service conditions
indicated in the Technical Data and
Design Criteria sections.
WARNING
The Model F895 ECOH Sprinklers
described herein must be installed
and maintained in compliance with
this document, as well as with the
applicable standards of the National
Fire Protection Association, in addi-
tion to the standards of any other
authorities having jurisdiction. Fail-
ure to do so may impair the integrity
of these devices.
The owner is responsible for main-
taining their fire protection system
and devices in proper operating con-
dition. The installing contractor or
manufacturer should be contacted
relative to any questions.
TECHNICAL DATA
The 11.2 and 14.0 K-Factor, Model
F895 Extended Coverage Ordinary
Hazard (ECOH) Pendent, Recessed
Pendent and Upright Sprinklers are
rated for use at a maximum service
pressure of 175 psi (12,1 bar) and they
are available in the temperature rat-
ings and finishes indicated in Table A.
Recessed versions of the F895 ECOH
Sprinklers are obtained by utilizing the
Model F895 Pendent Sprinkler in com-
bination with the Model F700 Re-
cessed Escutcheon. The Model F700
Escutcheons are available either with
a chrome plated finish or a coated fin-
ish in any color.
The flow “Q” in GPM (LPM) is deter-
mined by the formula:
where the nominal sprinkler discharge
coefficient “K” equals 11.2 (161,3) or
14.0 (201,6), as applicable; and “p” =
pressure in psi (bar).
The F895 utilizes a 3 mm diameter
Bulb with a die-cast dezincification re-
sistant bronze alloy Frame. The Button
(bulb retainer) is phosphor bronze or
brass. The Gasketed Spring Plate con-
sists of a beryllium nickel disc spring
that is sealed on both its inside and
outside faces with a Teflon
gasket.
The Compression Screw is bronze and
the Deflector is brass.
The F700 Recessed Escutcheon pro-
vided for use with the F895 ECOH
Sprinklers (Ref. Figure B) has a Clo-
sure and Mounting Plate fabricated
from low carbon steel. The Mounting
Plate prongs, which are compressed
back into the Mounting Plate as the
Closure is pushed over it, maintain a
tight friction fit between the two pieces.
The Mounting Plate and Closure can
also swivel relative to each other and
compensate for non-perpendicularity
between the F895 ECOH Sprinkler
and the ceiling.
NOTES
Inquiries concerning the appropriate-
ness of lead coated sprinklers for a
given corrosive environment should
be submitted to the attention of the
Technical Services Department.
Lead coated sprinklers are not suit-
able for use in open sprinkler applica-
tions.
