Other Atlas-Soundolier Products
Atlas-Soundolier offers a wide variety of
products conforming to UL Standard 1480,
“General Signaling”, UL Standard 1480 “Fire
Protective Signaling” and UL Standard 2043
which covers use in Air Handling Spaces
(Plenums). Atlas-Soundolier also offers
products that have been approved by specific
local authorities for specific projects in those
localities. These products will not have the
general acceptance of the FR Series in a
fire-resistant ceiling application. However,
they will be valuable for their intended
applications. Contact Atlas-Soundolier for
more information on these products and
their applications.
Contractor-Constructed Solutions
In some localities, contractors have received
approval for non-fire-resistant loudspeaker
systems by constructing and installing fire-
resistant rear enclosures from drywall.
While these drywall boxes can meet local
codes, they are costly to build, cumbersome
to install and
the added weight of the
drywall may degrade the fire resistance
properties of the ceiling system.
In contrast, Atlas-Soundolier’s FR Series is
a pre-manufactured product that assembles
quickly on site with no special tools or
skills. The mineral-fiber FR Enclosure-Fiber
Kit weighs very little and the entire FR
Series Fire-Resistant Speaker Assembly
installs in a way that maintains the fire-
resistance properties of a properly installed
ceiling. The installed cost of an FR Series
system can be much less than the cost of a
system using contractor-constructed drywall
boxes, especially in markets where labor
costs are high.
