General
Description
The Central Model B, 8.0 K-factor
(17/32 inch orifice), Quick Response,
Extended Coverage Light Hazard
(ECLH) Horizontal Sidewall & Re-
cessed Horizontal Sidewall Sprinklers
are decorative glass bulb sprinklers
designed for use in light hazard
occupancies per NFPA 13 or FM
Installation standards.
They are designed for installation
along a wall beneath smooth & level
ceilings as defined in the applicable
installation standard. Horizontal
sidewall sprinklers are generally used
in lieu of pendent sprinklers because
of aesthetic, building construction, or
installation economy considerations.
The recessed version of the Model B
using a two-piece Series 4211
Recessed Escutcheon provides 3/4
inch (19,1 mm) of field adjustment. In
addition to its aesthetically pleasing
appearance, the adjustment provided
by the Recessed Escutcheon reduces
the accuracy to which the fixed pipe to
the sprinklers must be cut.
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.
