General
Description

The Model B-1 Upright and Pendent
Foam-Water Sprinklers are air-aspi­rating foam discharge outlets de­signed for use in foam-water deluge
systems. They are designed for flam­mable liquidrisks where it is desired to
apply foam from overhead sprinklers
(either upright or pendent) and where
follow-upwith plain waterina standard
spraysprinkler patternis necessaryas
in the case of NFPA 16, “Standard for
the Installation of Foam-Water Sprin­kler and Foam-WaterSpray Systems”.

Itis recommended thattheend user be
consultedwith respecttothe suitability
of thematerials of construction for any
given corrosive environment. The ef­fects of ambient temperature, concen­tration of chemicals,and gas/chemical
velocity, should be considered, at a
minimum, along with the corrosive na­ture to which the sprinklers may be
exposed.

The Model B-1 Foam-Water Sprinkler
is a redesignation for the Gem Issue
B-1 and Star Model B-1.

Operation

TheModel B-1 Foam-WaterSprinklers
are designed with a unique venturi
style body. As foam solution (water
and foam concentrate mixture) flows
through the inlet of the body, air is
drawn into thebody through the open­ings adjacent to the wrenching area.
The foam solution and air mix is then
agitated to create an air-aspirated
foam.

The B-1 Foam-Water Sprinklers are
designed to discharge foam in a pre­determined discharge pattern, as well
as to discharge water similar to stand­ard spray sprinklers. To meet the in­tent of NFPA 16, foam-water sprin­klers must be able to sufficiently

distribute water after depletion of the
foam concentrate.

Design
Criteria

The M odel B-1 Upright and Pendent
Foam-Water Sprinklers are intended
for fire protection systems designed in
accordance with the standard installa­tion rules for foam-water sprinklers
systems recognized by the applicable
Listing agency (e.g., UL Listing is
basedon the requirementsofNFPA13
and 16).

Figure 2 provides the nominal dis­charge patterns for reference use.

NOTE

The discharge patterns shown in Fig­ure 2 are not to be used for design
purposes or to disregard standard in­stallation rules.

Not l ess tha n two foam-wat er spri n­klers are to be installed in any area,
regardless of size, in order to obtain
pattern overlap.

The applied density (flow per unit of
area) of foam solution must meet the
requirements of the Authority Having
Jurisdiction for the type flammable liq­uidand occupancy.Per NFPA 16,cov­erage density must not be less than

0.16 GPM/ft2(6,52 mm/min) of floor

area with a resulting minimu m dis­chargepressure ofnot less than30 psi
(2,1 bar).

Foam-water sprinkler spacing must
not exceed the requirements of NFPA
13 for extra hazard occupancies and
the system must be hydraulically cal­culated to obtain the required density
and discharge pressure.

NOTE

Discharge outlets and foam concen­trates are Listed for use together. Re­fer to the individual foam concentrate
Listing for operating limitations and
compatibility withthe B-1 Foam-Water
Sprinklers as provided in the UL Fire
Protection Equipment Directory.

Installation

TheModel B-1 Foam-WaterSprinklers
must be installed in accordance with
the following instructions:

NOTE

A leak tight1/2 inchNPT sprinklerjoint
should be obtained with a torque of 7
to 14 ft.lbs. (9,5 to 19,0 Nm). A maxi­mum of 21 ft. lbs. (28,5 Nm) of torque
may be used to install sprinklers with
1/2 NPT connections. Higher levels of
torque may distort the sprinkler inlet
and causeimpairment of the sprinkler.

Step 1. Pendent sprinklers are to be
installed in the pendent position, and
upright sprinklersare to be installedin
the upright position.

Step 2. With pipe thread sealant ap­plied to the pipe threads, hand tighten
the sprinkler into the sprinkler fitting.

Step 3. Tighten the sprinkler into the
sprinkler fitting using an 8 or 10 inch
adjustable Crescent wrench. With ref­erence to Figures 1 and 3, the adjust­able Crescent wrench is only to be
applied to the wrench flats of the
wrenching area.
