Data
The Omega Model HEC-12EC
Sprinkler is the most versatile
horizontal sidewall sprinkler ever
produced. It is a low profile,
aesthetically pleasing, wall mounted
sprinkler that operates five to six times
faster than a standard sprinkler. It
offers a high degree of protection for
human life and features a spray
pattern that has been shown to be
effective in the control or
extinguishment of fire.
The Model HEC-12EC carries two
separate Listings* by Underwriters

white, with additional special finishes

Operation: A fusible alloy pellet is
compressed with a bearing disc into
a copper housing by a ball plunger.
Heat is absorbed by the heat
collecting fins and conducted to the
alloy pellet. At the rated temperature
the alloy melts, causing the ball
plunger to drop, freeing balls from
the retaining groove. This movement
allows system water pressure to
force the orifice sealing mechanism
and deflector assembly open. Water
is then discharged in a designed flow
pattern.
