Model GFR VELO–ECOH Extended Coverage Ordinary Hazard Pendent and Recessed Pendent Sprinklers

Description
The Reliable VELO–ECOH Extended
Coverage Sprinkler has
a very extra large orifice with a
nominal K=14 (200). It can provide
OrdinaryHazardprotection
to 400 ft2 (37.2m2) at lower pressures
than an XLO which has a
nominal K=11.2 (160). VELO
sprinklers are standard response
and are available in a
pendent or an attractive recessed
pendent type which
providesup to¾(19mm)of escutcheon
adjustment. Various
finishes are available.
Reliable VELO–ECOH sprinklers provide protection inOrdinary
HazardGroup 1 and 2Occupancies to 400 ft2 (37.2m2)
per sprinkler when the system is designed to NFPA 13 hydraulic
density requirements.

ECOH pendent and recessed pendent sprinklers are to
be installed according to the design criteria shown in this
bulletin. The use of ECOHsprinklers can provide lower system
installation costs by requiring fewer sprinklers, less piping
and reduced labor.
Model GFR VELO sprinklers use a levered fusible alloy
solder link.
Design Criteria
Reliable Model GFR VELO—ECOH sprinklers shall only
be used in systems designed and installed in accordance
withNFPA13 and all other local codes and ordinances. The
following design criteria also apply:
 Minimum sprinkler spacing is 13 ft. (4.0m).
 Sprinklers have a minimum flow requirement for each
spacing as shown in the “Flow Requirements” Table
on the reverse side.
 ECOH sprinklers are only to be used in systems hydraulically
designed per NFPA 13 and for a minimum
area of 1500 ft2 (139m2) or 5 sprinklers, whichever is
greater.
 Deflector to commodity clearance shall be aminimum
of 18 (457mm).
 ECOH sprinklers shall be installed in unobstructed
constructions as defined in NFPA 13. For open web
truss construction web thickness is not to exceed 1
(25mm).
 ECOHsprinklers,which are installed above the bottom
of a horizontal obstruction, shall have their deflectors
located as shown in the “Obstruction Table” on the reverse
side.
 Sprinklers can be installed under a sloping ceiling not
exceeding 2 inches (50mm) of rise in 1 ft. (0.3m).
 Maximum working pressure is 175 psi (12 bar) at the
sprinkler.
