The University Sound CSP410-4T loud-
speaker system is a complete full-range
ceiling loudspeaker package. The package
consists of a bezel assembly and a speaker
assembly. The bezel assembly mounts to the
ceiling structure using a series of locking
spring connectors. No tools are required to
secure the bezel. The speaker assembly
consists of the speaker component, trans-
former and grille premounted in a steel
backcan. The bayonet slots on the speaker
assembly mate with the pins on the bezel to
provide an easy yet secure installation. The
bezel and perforated grille are finished in semi-
gloss white powder-coated enamel which
offers a cosmetically-appealing exterior.
The loudspeaker features a 4-inch curvilin-
ear cone with high-linearity treated cloth
surround together with a high-temperature
voice-coil assembly. The CSP410-4T
provides wide and uniform dispersion
throughout the critical speech bandwidth.
Transformer taps are offered at 0.5, 1, 2 and
4 watts, delivered to the loudspeaker system
using either 70-V or 100-V lines.
The rear enclosure provides an optimum
internal volume ensuring extended low-fre-
quency performance. It is constructed from
heavy-gauge, rugged cold-rolled steel, and
finished with a rust-inhibiting zinc plating.
A rear cover. with provisions for a junction
box fitting, provides access to an 8-pin ter-
minal block that allows direct connection to
each of the transformer (aps.
An optional tile bridge system 1s available
for safe suspension of the CSP410-4T in a
drop ceiling that uses mineral-wool or other
fiber-based ceiling tiles.
The CSP410-4T has been designed to work
as a complete system in a wide range of
different ceiling constructions. They provide
wide dispersion, high efficiency, high maxi-
mum output, ease of installation, and wide-
range reproduction of music or voice.
Mounting the System in a Ceiling
The University Sound CSP series ceiling
speaker systems have been designed to
accommodate a wide range of ceiling tile
and structural ceiling materials. The spring
assemblies can accommodate a range of
material thicknesses from 0.375-inch up
to 1.25-inch thick.
Before beginning the installation, determine
the type of material employed in the ceiling.
For all “soft” ceiling tiles, it is imperative that
the optional CTB-4 ceiling tile bridge be uti-
lized. The support rails are 603-mm (23.75-in.)
long and will support a loudspeaker system
in à 2 ft x 4 ft (or 2 ft x 2 ft) tile. In addition,
if angled at 10 to 15 degrees, the tile bridge
can be used with 600-mm tiles (see Figure A).
Figure À
Ceilings constructed from particle board,
plywood, gypsum board or plaster do not
normally require the use of a tile bridge.
However, additional safety 15 assured when
using a tile bridge.
Preparing the Wires
The ceiling system includes an eight-way bar-
rier strip that provides access to each of the
transformer taps. Bare-wire connection (up
to #10 gauge wire) should be used, and a
choice of both screw terminal, or spring-

loaded push terminals, have been provided
(see Figure B). The recommended strip length
is 6.4 mm to 8.0 mm (0.250 in. to 0.312 in.).

Using Conduit Fittings
The rear cover has provisions for the use of a
junction box, or gland nut style fitting
(see Figure C). This allows either solid or
flexible conduil to be connected directly to
the system. If local codes require the use of
conduit, ensure that it is well supported. Too
much unsupported weight may prevent the
ceiling system from closing flush against the
ceiling surface.
Selecting a Transformer Tap
The transformer tap of choice can be ob-
tained by making connection between the
ground terminal (#1) and any of the watt-
age taps indicated on the input label (#5,
#6, #7 or #8). Either 70-V or 100-V lines
can be used—reter to the input panel label
to determine the appropriate wattage for the
line voltage used (see Figure B).
Cutting Mounting Holes
« The hole for the 4-inch systems should
be 171 mm (6.75 in.) in diameter.
(See Figure D)
* The hole tor the 6.5-1nch systems should
be 203 mm (8.00 in.) ın diameter.
* The hole for the $-inch systems should
be 241 mm (9.50 in.) in diameter.
Check for electrical conduit/wiring and other
hazards before cutting the hole. In addition,
allow sufficient clearance for both the depth
of the loudspeaker/enclosure and any elec-
trical fittings used.

T-Bar Support
The T-bar system 15 comprised of two sup-
port bars and a support bridge. The bars are
inserted through tabs formed in the two sides
of the bridge and can be adjusted to allow
the cut out to be positioned at any point on
the width of, for example, a 4 ft by 2 ft ceil-
ing tile. Additionally, the tile bridge system
can be moved along the drop ceiling sup-
port rails and positioned at any point along
the length of a ceiling tule. The ceiling bridge
should be positioned directly above the hole
cut in the ceiling tile with the bridge resting
directly against the rear of the tle.
Bezel/Spring Assembly
The bezel/spring assembly is installed from
“room side” by pushing the inner tubular sec-
tion up through the hole cut in the ceiling
tile. If a tile bridge 1s used, the bezel's inner
tube will also pass through the hole in the
tile bridge. The clamp springs ([3] for the
4-inch and 6.5-inch systems and [4] for the
8-inch system) should be released, one at a
time, by reaching through the hole. Ensure
Figure D
that the metal arms are seated firmly and
evenly on the ceiling tile or ceiling tile/bridge
combination (see Figure E). Lock the springs
into place by pulling back and securing be-
hind the flange in the bracket.
Loudspeaker System Assembly
Before installing the ceiling loudspeaker sys-
tem, it is necessary to pull the hook up wire
downwards through the hole in the ceiling and
make electrical connection to the terminal
block on the rear cover - see Using Conduit
Fittings section. If required by local regula-
tions a mounting point is provided on the rear
cover that can be used for the attachment of a
safety chain or wire, (See Figure C)
The speaker assembly can be installed by
pushing it through the central opening of the
bezel assembly and then rotating the unit
until the “pins” on the bezel align with the
“bayonet” slots on the grille (see Figure F).
Verify the unit has seated firmly.
Removing a Loudspeaker System
A loudspeaker sysiem can be removed by
pushing upwards on the grille and rotating
the speaker assembly until the pins on the
bezel escape the bayonet slots on the grille
(see Figure F). Disconnect the safety chain
or cable, if employed, and disconnect the
electrical connection.

Painting Loudspeaker Assemblies
The bezels may be painted before or after
installation. Use conventional spray or roller
equipment to paint the loudspeaker bezel
when the rest of the ceiling is painted. La-
tex and oil based paints will adhere easily to
the loudspeaker bezel, but can scratch if
handled carelessly.
Grille/Loudspeaker Assemblies
Brushes or rollers may clog the grilles, in-
terfering with the acoustic performance of
the ceiling system. Additionally, a high-pres-
sure spray system may damage the paper
cone. Instead. spray paint the grilles with
lacquer or enamel paint in aerosol cans. (A
professional, siphon-feed spray gun may be
used provided the pressure 1s sufficiently low
to prevent cone damage). Place the grille /
loudspeaker system on a flat surface facing
upwards. Clean the grilles first to remove
all possible contaminants. Apply the paint
at a 45 degree angle to the grille surface (see
Figure G). Rotate the grille 180 degrees and
apply a second coat of paint. Alternatively
the grille can be removed from the loud-
speaker enclosure by the removing the three
self-tapping screws in the vertical section of
the grille (see Figure F).
