2) UL Recognition (Component Recognition)
UL’s Component Recognition Service
covers the evaluation of components
or materials that will later be used in
a complete product or system. These
components are products that are
incomplete in construction, restricted
in performance capabilities or
otherwise intended only for incorpo-
ration into other end-use products that
may be eligible for UL’s Listing,
Classification or Certificate Service.
3) UL Classification
Classification means that UL has tested
and evaluated representative samples
of a product with respect to certain
properties of the product, a limited
range of hazards or suitability of use
under limited or special conditions. UL
Classifies products to applicable UL
requirements and Standards
for Safety as well as to the
standards of other national
and international
organizations such as the NFPA,
ASTM, NSF International, ISO and IEC.

The FR Series Fire-Resistant Speaker
Assemblies are UL Classified, under UL
Standard 263,
“Fire Tests of Building
Construction and Materials”,
for use in
32 different 1-hour, 2-hour and 3-hour fire-
resistant ceiling system designs as listed in
the 1999 UL Fire Resistance Directory.
It is
important to understand that not every fire-
resistant ceiling system will necessarily
conform to one of these 32 UL-specified
designs. Fortunately,
the local fire marshal
or building inspector has the ultimate
authority to approve the use of the FR Series
in a fire-resistant ceiling and most will
welcome the FR Series because of its UL
Classification.
To assure this approval, consult with these
local authorities in a project’s design stages,
work closely with the ceiling system designers
and installers and be sure to install the FR
Series according to Atlas-Soundolier guidelines.
