Omega HEC-12

Product
Description

The Omega Model HEC-12

sprinkler is an extremely versatile
horizontal sidewall sprinkler.  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-12 carries a

Listing* by Underwriters Laboratories
for use as a Quick Response
Sprinkler that is listed for installation
in light hazard and ordinary hazard
occupancies in accordance with
current NFPA 13 Standards.

  The Model HEC-12 is available in

three standard finishes, chrome
plated, brass plated and white
painted.  Its mating escutcheon plate
is available in three standard finishes,
chrome plated, brass plated and
white painted, with additional special
finishes available upon request.

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.
