General
Description
The Central Model BV-QR, 4.2 & 5.6
K-factor (7/16" & 1/2" orifice) & Model
BVLO-QR, 8.0 K-factor (17/32" orifice),
Upright, Pendent, and Rec. Pendent
Sprinklers are quick response - standard
coverage, decorative glass bulb type
spray sprinklers designed for use in light &
ordinary hazard, commercial occupancies
such as banks, hotels, shopping malls etc.
The recessed version of the Central Model
BV-QR, intended for use in areas with a
finished ceiling, uses a two-piece Model
BV Res/QR Recessed Escutcheon
(Vented or Unvented). The Model BV
Res/QR Recessed Escutcheon provides
up to 3/8 inch (9,5 mm) of total adjustment
from the flush pendent position. The
recessed version of the Central Model
BVLO-QR, also intended for use in areas
with a finished ceiling, uses a two-piece
Model ELO Recessed Escutcheon. The
Model ELO Recessed Escutcheon
provides up to 3/4 inch (19,1 mm) of total
adjustment from the flush pendent
position. The adjustment provided by
these Recessed Escutcheons reduces the
accuracy to which the fixed pipe drops to
the sprinklers must be cut.
These sprinklers are available with a
polyester coating that may be utilized to
extend the life of copper alloy sprinklers
beyond that which would otherwise be
obtained when exposed to corrosive
atmospheres.
Although polyester coated sprinklers have
passed the standard corrosion tests of the
applicable approval agencies, the testing
is not representative of all possible
corrosive atmospheres. Consequently, it is
recommended that the end user be
consulted with respect to the suitability of
this corrosion resistant coating for any
given corrosive environment. The effects
of ambient temperature, concentration of
chemicals, and gas/chemical velocity,
BV-QR & BVLO-QR
should be considered, as a minimum,
along with the corrosive nature of the
chemical to which the sprinklers will be
exposed.
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 & flow water.
WARNING
The Model BV-QR & BVLO-QR Upright,
Pendent & Rec. Pendent 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.
The owner is responsible for maintaining
their fire protection system and devices in
proper operating condition. The installing
contractor or sprinkler manufacturer
should be contacted relative to any
questions.
