this corrosion resistant coating for any
given corrosive environment. The effects
of ambient temperature, concentration of
chemicals, and gas/chemical velocity,
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.

Pendent, Horizontal Sidewall and Rec.
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.
The owner is responsible for maintaining

General
Description
The Central Model BV-EC, 5.6 K-factor
Quick Response, Extended Coverage
Light Hazard (ECLH) Pendent, Recessed
Pendent, Horizontal Sidewall & Recessed
Horizontal Sidewall Sprinklers are
decorative glass bulb sprinklers designed
for use in light hazard occupancies such
as churches, hospitals, offices, and
restaurants.
They are intended for use in automatic
sprinkler systems designed in accordance
with standard installation rules (e.g., NFPA
13) for the protection of light hazard
occupancies. The pendent and recessed
pendent sprinklers are listed as quick
response sprinklers for a maximum
coverage area of 400 ft
2
(37,2 m
2
), as
compared to the maximum coverage area
of 225 ft
2
(20,9 m
2
) for standard coverage
sprinklers. The horizontal sidewall
sprinklers are UL listed with a maximum
ceiling to top of deflector distance of 18
inches (457,2 mm), the maximum allowed
by NFPA.
The recessed version of the Central Model
BV-EC, intended for use in areas with a
finished ceiling/wall, 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 or horizontal
sidewall position.
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
