RESIDENTIAL QUASAR
MODEL Q
GENERAL DESCRIPTION
The Quasar Model Q is the world's only self-adjusting resi-
dential concealed sprinkler. The Quasar's unique patented
cover assembly not only provides a full 1/2" of adjustment,
but it is also the only concealed sprinkler cover assembly
which automatically moves with normal ceiling fluctuations.
The Quasar's cover assembly design virtually guarantees
that the cover will not only stay on but will also remain tight to
the ceiling,eliminating unsightly gaps and shadows.
Quasar cover plates are available in a variety of finishes.
Custom decorator finishes are factory applied to match cus-
tomer supplied color samples for every decorating need.
Standard finishes are white painted or chrome plated.
ADeluxe finishes include black,polished brass, and brushed
zinc.
Another Quasar time and money saving feature is the fac-
tory applied Star-Seal thread sealant, which eliminates the
need to apply pipe compound or tapes in the field. This fea-
ture, plus the 1/2" of adjustment which allows for pre-cut
drops, makes Quasar installation a snap.
It is quick and simple to remove Quasar covers, which
allows for easy removal of ceiling tiles without shutting down
the sprinkler system. Quasar sprinklers also come with a
temporary protective cover. This cover protects the sprinkler
during construction, helps with installation, and can be used
for temporary fire protection.
OPERATION
The simple two-step operation of the Quasar makes it one
of the most dependable fire sprinklers available. The Resi-
dential Quasar sprinkler responds to fire much faster than
standard sprinklers to help reduce fire damage. The Quasar
cover plate is factory attached to the cover assembly with a
eutectic alloy. When a fire occurs, the alloy melts at a prede-
termined temperature and the cover plate falls away. After
the cover plate has fallen, the deflector drops and the sprin-
kler is exposed to the fire's heat. The Quick Response glass
bulb in the sprinkler reaches its operating temperature and
the fluid inside expands, forcing the bulb to shatter, which
activates the sprinkler. Upon activation, water is discharged
in a predesigned pattern to control or extinguish the fire.
