than the recommended 2 1/4"
diameter. The escutcheon closure
plate fits between the base of the
escutcheon and the mounting
surface.
For all models of Prohibitor
TM
sprinklers, an optional 4 1/2"
diameter x 1/8" thick security closure
plate is
available for use where
additional security is a consideration.
The security closure greatly reduces
the possibility of inserting a tool,
prybar or other device behind the
sprinkler. The security closure plate
fits between the base of the
escutcheon and the mounting
surface.
For all models of Prohibitor
TM
Sprinklers, the optional Ident-A-Fire
TM
feature is available to provide an
alarm signal upon activation of the
sprinkler.
Prohibitor
TM
Sprinklers are
available in two standard finishes,
chrome and brass. Their mating
escutcheon is available in three
standard finishes, chrome plated,
brass plated and white painted, with
additional special finishes available.
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.
The Omega Prohibitor
TM
Model
HEC-12 PRO Automatic Sprinklers
have been specifically designed for
use in institutional occupancies, such
as correctional facilities and mental
health facilities, where the occupants
may attempt to tamper with or
otherwise employ the sprinkler to
injure themselves or others.
The horizontal sidewall style
Prohibitor
TM
HEC-12 PRO sprinklers
are recessed into the mounting
surface with only a portion of the heat
collecting fin assembly projecting into
the protected space. The heat
collecting assembly has an average
breakaway load of 68 lbs., and a
maximum breakaway load of 85 lbs.
Unlike other institutional sprinklers,
the escutcheon plate and optional
closure plates are firmly attached to
the recessed sprinkler body with
tamper resistant retaining screws.
The Omega Prohibitor
TM
sprinklers
are designed with an aesthetically
pleasing, low profile silhouette. They
feature a spray pattern that has been
shown to be effective in the control or
extinguishment of fire.
The Model HEC-12 PRO is a
Horizontal Sidewall Sprinkler Listed
for standard sidewall applications with
the deflector positioned 4" to 12"
below the ceiling.
For all models of Prohibitor
TM
Sprinklers, an optional 3 5/8"
diameter light gauge escutcheon
closure plate is available, for use
where the wall penetration is greater
