Description
The Central Model ELO-16 GB FR Extra
Large Orifice Upright, Pendent and Recessed
Pendent Glass Bulb Automatic Sprinklers are
designed for Extended Coverage spacing in
Ordinary Hazard occupancies per NFPA 13
with very low pressure required.
The ELO-16 GB FR (upright and pendent)
is the first extended coverage ordinary hazard
sprinkler ever Approved by Factory Mutual.
As with any project that requires Factory
Mutual Approval, always consult the F.M.
Guidelines for their specific requirements.
The Model ELO-16 GB FR incorporate a
specially designed deflector that provides a
much greater area of coverage than most
commercial sprinklers. The extra large orifice
allows this greater area of coverage, while
requiring much lower pressure.
The ELO-16 GB FR are intended for use,
as all extended coverage sprinklers are, with
hydraulically designed systems and using the
flows and pressures as shown in this bro-
chure. All spacing is rounded up to the next
higher category. For example, 17'-6" x 15'-0"
(4.4m x 3.8m) spacing would be calculated at
the Listed 18' x 18' (5.5m x 5.5m) flow and
pressure.
Operation: The glass bulb capsule
operating mechanism contains a heat-
sensitive liquid that expands upon application
of heat. At the rated temperature, the
frangible capsule ruptures, thereby releasing
the orifice seal. The sprinkler then discharges
water in a pre-designed spray pattern to
control or extinguish the fire.
Installation Limitations:
• Unobstructed or non-combustible
obstructed construction*
• Minimum hydraulic design area of 5
heads or 1500 sq. ft., whichever is
greater.
• Minimum spacing between sprinklers is
12' (3.7m) for upright and 12'-6" (3.81m)
for pendent.
* WEB members of open WEB trusses must not exceed
1" (25 mm) diameter. Maximum ceiling slope of 2"
per foot (158 mm/m) .
