General
Description
The Central Model ELO SW-20,
11.2 K-factor, Standard Response,
Extended Coverage Ordinary Hazard
(ECOH) Horizontal Sidewall Sprin-
klers are decorative glass bulb
sprinklers designed for use in ordinary
hazard occupancies per NFPA 13.
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.
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.
