loudspeaker model.
GENERAL NOTES
CAUTION: IF YOU ARE INSTALLING A UL LISTED
PRODUCT, PLEASE REFER TO THE “UL1480
LISTED MODELS” SECTION FURTHER IN THIS IN-
STRUCTIONS PRIOR TO BEGINNING ANY WORK.
•
Make sure loudspeaker model, mounting
configuration and installation hardware is compat-
ible and appropriate for the selected application.
Verify all components to be used are in conformity
to local building requirements. System Engineers
and Installers must always consult with the Local
Authorities in order to obtain specific requirements
of an installation or product utilization. Please refer
to the “Models” section and “Product-specific”
notes for more information.
•
Make sure wiring methods, conduit, clamping,
interconnection, sealing and termination proce-
dures comply with NEC and the appropriate Local,
Electrical and Building Codes.
•
It is strongly recommended that all ceiling
installations be done using the TBS8-10 Tile
Bridge. The TBS8-10 provides important structural
support and is an advisable safety practice,
whether required by code or not.
•
A TBS8-10 bridge or similar is always required
when installing CT8B/CT10B models with torsion
springs, unless the selected backcan or plaster
ring has torsion spring receptacles “built-in”.
•
Hanging straps are normally provided on the
PBB8-10 backcan and in most industry standard
backcans. These should be used to attach the
backcan (or backcan/bridge assembly) to the roof
or other structural point, to support and suspend
the load. It is good safety practice to use this
option even if not required by local codes.
•
Some Building/Electrical Codes may have
specific installation requirements to be met, and
may additionally require the use of fastener clips or
seismic rings to attach the assemblies to the
ceiling tile grid. Please consult the authorities
having jurisdiction in this regard. The “Seismic
Safety Ring” is designed to secure the tile bridge
to the fire barrier/plenum ceiling before the
speaker assembly or backcan is installed, provid-
ing additional safety along with maintaining the
integrity of the ceiling before the speaker is
installed.
•
The recommended minimum clearance behind
the surface where the loudspeaker is to be in-
stalled is the depth of the backcan/tile bridge
assembly plus four inches.
•
The loudspeaker carton contains a cutout
template that provides cutting diameters for most
installation hardware. Please review the notes
printed in the packaging carton to determine the
proper hole size.
•
If working on a retrofit installation using torsion
spring mounting hardware insure that existing
backcans have sufficient room for the torsion
springs to open when inserted, and that the spring
receptacles are the flat, slotted type.
PRODUCT-SPECIFIC NOTES
•
When a PBB8-10 / TBS8-10 combination is to
be used, the four J-Nuts from the Tile Bridge must
be removed. For other types of backcans including
surface mount or beam clamp, please refer to the
installation instructions and recommendations
provided by the backcan’s manufacturer.
•
The TBS8-10 Tile Bridge has locking tabs on
the center plate that can be bent down to prevent
the bridge from moving during installation, and
horseshoe tabs that allow the Tile Bridge and
backcan to be mechanically interlocked. Please
refer to the instructions provided with the TBS8-10.
•
The TBS8-10 Tile Bridge must be set according
to the selected loudspeaker mounting configura-
tion (screw/stud or torsion spring). For screw or
stud/nut mount applications, the TBS8-10 Tile
Bridge must be oriented with the center pan
closest to the ceiling tile. For torsion spring mount
installations, the Tile Bridge must be inverted in
order to obtain a proper fit.
•
We do not recommended installing a CT8B/
CT10B loudspeaker with torsion spring mounting
hardware in walls and fascias. The springs may be
subject to uneven compression, which can result
in speaker displacement.
•
Backcans and Plaster Rings with the U-shaped
torsion spring receptacles are NOT compatible
with SOUND ADVANCE products. Make sure the
torsion spring receptacles of the selected hard-
ware are the flat, slotted type (i.e.: Soundolier T-95
Series backcans and T-75 plaster rings).
