Description
The Tyco
®
Model EC-17 Extended
Coverage Pendent Sprinklers (Ref.
Figure 1) are “Control-Mode Extended
Coverage Sprinklers” having a nomi-
nal K-factor of 16.8. Their use is espe-
cially advantageous as a means of de-
creasing the number of required
sprinklers to protect occupancies re-
quiring an area/density application of
water.
Features:
•
The EC-17 Sprinklers offer a maxi-
mum coverage area of 196 ft
2
(18,2
m
2
) at a maximum spacing of 14 feet
(4,3 m), almost double that of stand-
ard coverage sprinklers used for
similar applications.
•
The EC-17 Sprinklers offer a maxi-
mum coverage area of 144 ft
2
(13,4
m
2
) at a maximum spacing of 15 ft.
(4,3 m) which can be beneficial to
maximizing sprinkler line spacing.
•
The 144 ft
2
(13,4 m
2
) coverage with
maximum spacing of 15 ft. (4,3 m)
for the EC-17 Sprinklers can be
beneficial for retrofitting an existing
system to a higher applied water
density, especially where the sys-
tem had utilized sprinklers having a
maximum sprinkler spacing of 15
feet (4,3 m).
The recessed version of the Model EC-
17 Pendent Sprinkler is intended for
use in areas with a finished ceiling. It
uses a two-piece Style 30 (3/4 inch
NPT) Recessed Escutcheon with 1/4
inch (6,4 mm) of recessed adjustment,
or up to 1/2 inch (12,7 mm) of total
adjustment from the flush pendent po-
sition. The adjustment provided by the
Recessed Escutcheon reduces the ac-
curacy to which the fixed pipe drops to
the sprinklers must be cut.
Applications for the Model EC-17
Sprinklers are expanding beyond the
current testing. For information re-
garding additional research fire tests
that may be acceptable to an Authority
Having Jurisdiction please contact the
Technical Services Department.
