Description
The Residential Optima™ Concealed
is the world's first 20' x 20' concealed
residential sprinkler. It is UL Listed
for residential occupancies as
outlined in NFPA 13, NFPA 13D and
NFPA 13R with very low flows and
pressures while providing the
aesthetic appeal of a flat concealed
ceiling plate.
It is designed to compensate for
varying ceiling heights by utilizing a
drop down deflector and an
adjustable thread-on escutcheon.
This feature is significant because it
allows the ceiling to fluctuate over
in height. The thin cover plate
projects only 3 ⁄ " below the ceiling for
16
the maximum in unobstructed and
aesthetic appearance.
To prevent damage to the sprinkler
and to allow the sprinkler to be
located in the ceiling, a special
protective cap is provided. This plastic
cap has a cone shaped point that can
be pressed against the wall board to
locate the position of the sprinkler and
allow the hole to be cut correctly.
The Residential Optima™ Concealed
Sprinkler employs Central's exclusive
link activating mechanism. The
sprinkler is brass and the cover plate
is available in brass, chrome plated or
white painted.
Operation: The Central Residential
Optima Concealed Sprinkler absorbs
heat through the ceiling cover plate
Concealed
™
which is soldered to the adjustable
retainer ring with a fusible alloy. At
the rated temperature, the alloy
fuses, resulting in the plate dropping
away from the sprinkler. At this point,
the deflector drops down below the
ceiling surface, bringing about the
link's exposure to the fire's heat. The
heat fuses the link's thermal element
resulting in a rapid expulsion of both
the activating mechanism, as well as
the sealing cap. Water can now flow
in a pattern engineered to meet the
coverage requirements.
