General
Description
The Central Model BV-R1, 5.3
K-factor Residential Pendent and
Recessed Pendent sprinklers are
decorative glass bulb sprinklers
designed for use in residential
occupancies such as homes, apart-
ments, 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 occupancy per NFPA 13.
The recessed version of the Model
BV-R1 Residential Pendent Sprinkler
is obtained by utilizing the Model
BV-R1 Residential Pendent Sprinkler
in combination with the Model BV
Res./QR Recessed Escutcheon
Assembly. The recessed version of
the Central Model BV-R1 using a
Model BV Res./QR Recessed
Escutcheon provides up to 3/8 inch
(9,5 mm) of total adjustment from the
flush pendent position.
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.
WARNING
The BV-R1 Residential Pendent
Sprinklers described herein must
be installed and maintained in
compliance with this document, as
well as with the applicable stan-
dards of the National Fire Protec-
tion Association, in addition to the
standards of any other authorities
BV-R1
having jurisdiction. Failure to do so
may impair the integrity of these
devices.
Because of the above cited stipula-
tions 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
maintaining their fire protection
system and devices in proper
operating condition. The installing
contractor or sprinkler manufac-
turer should be contacted relative
to any questions.
