Description
The Central Model ESLO Very Extra
Large Orifice Recessed Pendent and
Pendent Automatic Glass Bulb Sprinklers
are specifically designed for Extended
Coverage/Light Hazard for all Groups as
defined by NFPA 13. They are Listed as
Quick Response, up to 18'x18' spacing,
and as Standard Response, above 18'x18'
spacing. Maximum ceiling slope of 2" per
foot. The ESLO is Listed for smooth flat
horizontal ceilings as are all Extended
Coverage Light Hazard Sprinklers.
The ESLO provides the maximum in
design flexibility as it has a minimum
separation of only 9'-0" and is Listed for
flows and pressures associated with
16'x16', 18'x18' and 20'x20' spacing.
They are intended for use, as all ex-
tended coverage sprinklers are, with
hydraulically designed systems and using
the flows and pressures as shown in this
brochure. For the purpose of determining
the correct flow and pressure to use in the
hydraulic calculations, all spacing is
rounded up to the next higher category.
For example, 17'-6"x15'-0" spacing would
be calculated at the Listed 18'x18' flow and
pressure.
The advantage of the ESLO is the ability
to cover large areas, up to 400 square
feet, with pressures that compare to
1

"
standard sprinklers spaced at their
maximum of 225 square feet. For ex-
ample, the ESLO can cover 20'x20'
spacing or 400 square feet with less
pressure than is required with

" sprin-
klers at 225 square feet. (7.6 vs. 16.1)
The Model ESLO Sprinkler incorporates
a specially designed deflector that pro-
vides a much greater area of coverage
than standard commercial sprinklers.
The two (2) piece recessed escutcheon
assembly provides for

ment.
