Tyco Fire Product CENTRAL BV-QR User manual

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.

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,

Ordering
Information
The Model BV-QR & BVLO-QR Sprinklers
must be maintained and serviced in
accordance with the following instructions.
NOTES
Absence of an escutcheon which is used
to cover a clearance hole, may delay the
time to operation in a fire situation.
Before closing a fire protection system
main control valve for maintenance work
on the fire protection system it controls,
permission to shut down the affected fire
protection systems must be obtained from
the proper authorities. All personnel who
may be affected by this action must be
notified.
Sprinklers which are found to be leaking or
exhibiting visible signs of corrosion must
be replaced.
Automatic sprinklers must never be
shipped or stored where their tempera-
tures will exceed 100°F/38°C and they
must never be painted, plated, coated or
otherwise altered after leaving the factory.
Modified sprinklers must be replaced.
Sprinklers that have been exposed to
corrosive products of combustion, but
have not operated, should be replaced if
they cannot be completely cleaned by
wiping the sprinkler with a cloth or by
brushing it with a soft bristle brush.
Care must be exercised to avoid damage
- before, during, and after installation.
Sprinklers damaged by dropping, striking,
wrench twist/slippage, or the like, must be
replaced. Also, replace any sprinkler that
has a cracked bulb or that has lost liquid
from its bulb (Ref. Installation Section).
Frequent visual inspections are recom-
mended to be initially performed for
polyester coated sprinklers installed in
corrosive environments, after the
installation has been completed, to verify
the integrity of the polyester coating.
Thereafter, annual inspections per NFPA
25 should suffice; however, instead of
inspecting from the floor level, a random
sampling of close-up visual inspections
should be made, so as to better determine
the exact sprinkler condition and the long
term integrity of the polyester coating, as it
may be affected by the corrosive condi-
tions present.
The owner is responsible for the inspec-
tion, testing, and maintenance of their fire
protection system and devices in compli-
ance with this document, as well as with
the applicable standards of the National
Fire Protection Association (e.g., NFPA
25), in addition to the standards of any
other authorities having jurisdiction. The
installing contractor or sprinkler manufac-
turer should be contacted relative to any
questions.
It is recommended that automatic sprinkler
systems be inspected, tested, and
maintained by a qualified Inspection
Service.
Installation
(Cont.)
21 ft.lbs. (28,5 Nm) of torque is to be used
to install 1/2 inch NPT sprinklers. A leak
tight 3/4 inch NPT sprinkler joint should be
obtained with a torque of 10 to 20 ft.lbs.
(13,4 to 26,8 Nm). A maximum of 30
ft.lbs. (40,7 Nm) of torque is to be used to
install 3/4 inch NPT sprinklers. Higher
levels of torque may distort the sprinkler
inlet with consequent leakage or impair-
ment of the sprinkler.
Do not attempt to compensate for
insufficient adjustment in an Escutcheon
Plate by under- or over-tightening the
Sprinkler. Readjust the position of the
sprinkler fitting to suit.
Step 1. Upright sprinklers must be
installed only in the upright position &
pendent sprinklers must be installed only
in the pendent position. The deflector is to
be parallel to the ceiling, roof, or mounting
surface, as applicable.
Step 2. After installing the BV Res/QR or
ELO support cup (or other escutcheon, as
applicable) over the sprinkler pipe threads
& with pipe thread sealant applied to the
pipe threads, hand tighten the sprinkler
into the sprinkler fitting.
Step 3. Wrench tighten the sprinkler using
only the following wrenches:
BV-QR Up/Pend - Comb. Wrench (1106)
BV-QR Rec. Pend - BV Wrench (1099)
BVLO-QR Up & Pend - W-Type 3 (1073)
BVLO-QR Rec. Pend - ELO Offset (1093)
Wrenches are to be applied to the
sprinkler wrench flats (Ref. Fig 2 & 3) only.
Step 4. For applications using the BV-QR
Rec. Pendent Sprinklers, a Protective Cap
is available which helps to prevent
damage to the sprinkler during ceiling
installation or during application of the
finish coating of the ceiling. Place the
Protective Cap over the Recessed
Support Cup and push it upwards until it
bottoms out against the sprinkler deflector.
NOTE
As long as the Protective Cap remains in
place, the system is considered "Out of
Service."
Step 5. After the ceiling has been
completed, remove and discard the
Protective Cap. If the sprinkler has been
damaged, replace the entire sprinkler
assembly. Do not attempt to modify or
repair a damaged sprinkler.
Step 6. Push the outer ring of the
Recessed Escutcheon over the Recessed
Support Cup. Do not continue to push on
the Recessed Escutcheon such that it lifts
a ceiling panel out of its normal position. If
the Outer Recessed Escutcheon Ring
cannot be engaged with the Recessed
Support Cup or the Outer Recessed
Escutcheon Ring cannot be engaged
sufficiently to contact the ceiling, the
sprinkler fitting must be repositioned.
