• Leave the installation to your TOA dealer because
the installation requires expert knowledge.
Improper installation may cause the unit to fall,
resulting in personal injury and/or property
damage.
• Install the unit in a location that can structurally
support the weight of the unit and its mounting
hardware. Doing otherwise may result in the unit
falling down and causing personal injury and/or
property damage.
• Do not use other methods than specified to mount
the unit. Extreme force is applied to the unit and
the unit could fall off, possibly resulting in personal
injuries.
• Attach the safety wire to the unit. If not attached,
the unit could fall off, resulting in personal injury.
• Tighten each screw securely. Ensure that the unit
has no loose joints after installation to prevent
accidents that could result in personal injury.
• Never hold the diffuser section as a handle to carry
the unit during installation. If the diffuser breaks off,
the unit could fall from an elevated position,
resulting in possible personal injury. (F-2352CU2
only)
• Use the specified mounting hardware in
combination. Doing otherwise may cause the unit
or component to fall off, resulting in personal injury.
• Should the following irregularity be found during
use, immediately stop operating the unit and
contact your nearest TOA dealer. Further attempt
to use under this condition may cause fire or
electric shock.
· If you detect smoke or a strange smell coming
from the unit
· If no tone sounds
• Avoid installing the unit in humid or dusty locations,
in locations exposed to the direct sunlight, near the
heaters, or in locations generating sooty smoke or
steam as doing otherwise may result in fire or
electric shock.
• Do not operate the unit for an extended period of
time with the sound distorting. This is an indication
of a malfunction, which in turn can cause heat to
generate and result in a fire.
• Avoid touching the unit's sharp metal edge to
prevent injury.
CAUTION

2. GENERAL DESCRIPTION
The F-2322CU2 and F-2352CU2 are flush-mounted Ceiling Speaker Systems that offer wide frequency range
of high-quality sound output.
The F-2322CU2 employs a full-range speaker element, while the F-2352CU2 features a 2-way speaker
configuration.
Both speaker systems are designed to be mounted to a drop ceiling with use of the supplied tile bridge.
3. FEATURES
• Bass-reflex speaker system designed to provide a wide frequency range and high power handling capability.
• Wide-dispersion flush-mount ceiling speaker design employs unique acoustic construction to realize a wide
area of coverage. Uniform sound output levels are achievable not only directly under the speaker, but also
over a wide radius.
• Because the speaker is provided with both low- and high-impedance operating capability, it can be used in
many different applications. Front panel-mounted input selector switch permits easy verification and change
of current impedance settings.
• Easy installation. Can be quickly and accurately mounted to ceilings.
• Rotating front grille can be installed quickly and conveniently.
• Attractive exterior design specially created by an interior designer blends naturally with any architectural
space, enhancing the immediate area's sense of harmony.

Loosen the screw to allow the speaker cable to pass through.
Choke bracket
Flexible conduit
Retighten the screw to fix
the flexible conduit.
Note
Ensure that the flexible conduit is securely fixed.
Connector cover
After completing the speaker cable connection, turn the connector cover
in the direction indicated by the arrow, and fix the cover with 2 screws.
Plug the wired input connector into the speaker's socket,
then pull the speaker cable from the choke bracket.
(For wiring the input connector, refer to p. 10.)
Accommodating larger diameter conduit
The choke bracket accommodates up to 3/8-inch
(9.5 mm) flexible conduit. When larger diameter
conduit should be fit, use a suitable fitting
commercially available by replacing the existing
choke bracket with it. Detaching the choke
bracket by unscrewing it exposes a 7/8-inch (22
mm) hole. Install the alternate fitting there.
6. WIRING
6.1. Wiring through Hard or Flexible Conduit
Note
The choke bracket equipped with the speaker has not been evaluated by UL, for conduit connection and
UL514B Standard.
Flexible conduit of 3/8 or 1/2 inch trade size and the UL514B conduit fitting of the same trade size can also be
used. When using the UL514 listed conduit fitting, detach the equipped choke bracket and mount the conduit
fitting instead.
