Operation
The glass bulb contains a fluid that
expands when exposed to heat. When
the rated temperature is reached, the
fluid expands sufficiently to shatter the
glass bulb, allowing the sprinkler to
activate and flow water.
Design
Criteria
The Series EC-8 Extended Cover-
age Pendent Sprinklers must only
be installed in accordance with the
applicable UL and C-UL Listing or
FM Approval requirements as indi-
cated below. Only the Style 30 or 40
Recessed Escutcheon is to be used
for recessed installation, as applicable
(Ref. Table A, B, and C).
UL and C-UL Listing Requirements
1.
The Series EC-8 Sprinklers may be
used for the coverage areas shown
in Table D, based on maintaining
the minimum specified flow rate
as a function of coverage area and
hazard group for all of the sprin-
klers in the design area.
2.
With respect to heat sensitivity, the
Series EC-8 Sprinklers can be used
with unobstructed construction
consisting of flat, smooth ceilings
(including bar joists) with a maxi-
mum pitch of one in six as defined
and permitted by NFPA 13.
3.
The minimum allowable spacing
between the Series EC-8 Sprin-
klers, to prevent cold soldering, is
8 ft (2,4 m).
4.
The Series EC-8 Sprinklers are
to be installed in accordance with
all other requirements of NFPA 13
for extended coverage pendent
sprinklers.
FM Approval Requirements
The Series EC-8 Extended Coverage
Sprinklers are to be installed in accor-
dance with the applicable Factory
Mutual Loss Prevention Data Sheet.
Information provided in the FM Loss
Prevention Data Sheet relate to, but are
not limited to, hydraulic design, ceiling
slope and obstructions, minimum and
maximum allowable spacing, and
deflector-to-ceiling distance.
