Glass Bulb Automatic Sprinkler
General
Description
The Central Model BVR, 5.4 K-factor
Residential Horizontal Sidewall &
Recessed Horizontal Sidewall Sprinklers
are decorative glass bulb sprinklers
designed for use in residential occupan-
cies 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 Horizontal Sidewall Sprinkler is
obtained by utilizing the Model BVR
Horizontal Sidewall Sprinkler in combina-
tion with the Model BV Res./QR Re-
cessed Escutcheon Assembly. The
recessed version of the Central Model
BVR using a Model BV Res./QR Re-
cessed Escutcheon provides up to 3/8
inch (9,5 mm) of total adjustment from the
flush Horizontal Sidewall 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 BVR Residential Horizontal
Sidewall 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
addition to the standards of any other
authorities 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

Criteria
The Model BVR Horizontal Sidewall and
Recessed Horizontal Sidewall Sprinklers
are UL, ULC Listed and MEA Approved
for use in accordance with current NFPA
standards for use on wet pipe sprinkler
systems. These sprinklers have been
investigated for use under smooth flat
horizontal ceilings with slopes up to 2
inches per foot, at spacings up to 16 feet
by 20 feet, using the design requirements
found in Table 1. These sprinklers have
also been investigated for use under
smooth flat sloping ceilings with slopes up
to 8 inches per foot, at spacings up to 16
feet by 20 feet, using the design
requirements found in Table 2 & 3 as well
as the sloped ceiling "Specific Application
Design Criteria" found in Figure 1.
The Recessed Horizontal Sidewall
Sprinklers are only listed with the Series
BV Res./QR Recessed Escutcheon
Assembly.
The minimum required single and multiple
sprinkler flow rates for systems designed
to NFPA 13D or NFPA 13R occupancies
are given in Table 1, Table 2, and Table 3.
The single sprinkler flow rate is the
minimum required discharge from the
most hydraulically demanding single
sprinkler and, the multiple sprinkler flow
rate is the minimum required discharge
from each of the total number of "design
sprinklers" as specified in NFPA 13D or
NFPA 13R.
