General
Description
The Central Model BVR, 4.3 K-factor
Residential Pendent, Recessed Pendent
and Concealed sprinklers are decorative
glass bulb sprinklers designed for use in
residential occupancies such as homes,
apartments, dormitories, and hotels.
They are to be used in wet pipe residential
sprinkler systems for one- and two-family
dwellings and mobile homes per NFPA
13D; wet pipe residential sprinkler
systems for residential occupancies up to
and including four stories in height per
NFPA 13R; or, wet pipe sprinkler systems
for the residential portions of any occu-
pancy per NFPA 13.
The recessed version of the Model BVR
Residential Pendent Sprinkler is obtained
by utilizing the Model BVR Residential
Pendent Sprinkler in combination with the
Model BV Res./QR Recessed Escutch-
eon Assembly. The recessed version of
the Central Model BVR using a Model BV
Res./QR Recessed Escutcheon provides
up to 3/8 inch (9,5 mm) of total adjust-
ment from the flush pendent position.
The concealed version of the model BVR
Residential Pendent Sprinkler is obtained
by utilizing the Model BVR Residential
Pendent Sprinkler in combination with the
Model BVR Concealed Cover Plate.
Operation: The glass bulb contains a fluid
which expands when exposed to heat.
When the rated temperature is reached,
the fluid expands sufficiently to shatter the
glass bulb, which then allows the sprinkler
to activate and flow water. For concealed
applications, the cover plate, which is
normally soldered to the retaining clip and
attached to the deflector of the BVR
Residential Sprinkler, falls away to expose
the sprinkler assembly.
WARNING
The BVR Residential Pendent Sprin-
klers 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 addition
to the standards of any other authori-
ties having jurisdiction. Failure to do so
may impair the integrity of these
devices.
Because of the above cited stipulations
and the varied nature of residential
type architecture, there will be some
compartment designs which cannot be
fully sprinklered in accordance with the
recomendations of NFPA 13, NFPA
13D, or NFPA 13R. In the event of this
condition, consult the authorities
having jurisdiction for guidance and
approval.
The owner is responsible for maintain-
ing their fire protection system and
devices in proper operating condition.
The installing contractor or sprinkler
manufacturer should be contacted
relative to any questions.
