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, which- then allows the
sprinkler to activate and flow water.
Design
Criteria
TYCO Series EC-11 and EC-14
Extended Coverage Upright and
Pendent Sprinklers must only be
installed in accordance with the appli-
cable UL and C-UL Listing or FM
Approval requirements as indicated
below. Only Style 30 or 40 Recessed
Escutcheons are to be used for
recessed installation, as applicable.
Refer to Tables A, B, and C, for more
information.
UL and C-UL
Listing Requirements
1.
Series EC-11 and EC-14 Extended
Coverage 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 haz-
ard group for all sprinklers in the
design area.
2.
Series EC-11 and EC-14 Extended
Coverage Sprinklers are permitted
to be used with unobstructed or
non-combustible obstructed ceil-
ing construction as defined and
permitted by NFPA 13; for example:
• Unobstructed, combustible or
noncombustible, ceiling con-
struction with a deflector to
ceiling/roof deck distance of
1 to 12 in. (25 to 300 mm).
• Obstructed, non-combusti-
ble, ceiling construction with a
deflector location below struc-
tural members of 1 to 6 in.
(25 to 150 mm) and a maximum
deflector to ceiling/roof deck dis-
tance of 22 in. (550 mm).
3.
Series EC-11 and EC-14 Extended
Coverage Sprinklers, specifically
tested and listed for non-combus-
tible obstructed construction, are
permitted to be used within truss-
es or bar joists having non-com-
bustible web members greater
than 1 in. (25.4 mm) when apply-
ing the 4 times obstruction crite-
ria rule defined under “Obstruc-
tions to Sprinkler Discharge Pattern
Development”.
4.
To prevent cold soldering, the
minimum allowable spacing be-
tween Series EC-11 and EC-14 Ex-
tended Coverage Sprinklers is 8 ft
(2,4 m) for upright sprinklers and 9 ft
(2,7 m) for pendent sprinklers.
5.
Series EC-11 and EC-14 Extended
Coverage Sprinklers are to be in-
stalled in accordance with all oth-
er requirements of NFPA 13 for
extended coverage upright and
pendent sprinklers; For exam-
ple, obstructions to sprinkler dis-
charge, obstructions to sprinkler
pattern development, obstructions
to prevent sprinkler discharge from
reaching hazard and clearance to
storage.
