• 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.

• 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

• 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.

2. GENERAL DESCRIPTION

The F-122CU is a flush-mounted ceiling speaker that offers a wide frequency range of high-quality sound output. Use of its supplied mounting hardware and optional HY-TB1 Tile Bar Bridge permits it to be versatilely mounted to match a wide range of applications and installation locations.

3. FEATURES

• 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.

5. MOUNTING HARDWARE INSTALLATION

Before mounting the speaker, determine the most appropriate method for the existing ceiling structure.

Be sure to use an optional HY-TB1 Tile Bar Bridge in combination with the supplied ceiling reinforcement ring.

[Installation view on Drop Ceilings]

Because the bridge rails are 603 mm (23 47/64") in length, be sure to match them to the ceiling tile size during installation.

Caution

Set the bridge rails so that both ends fit securely into the T-grids, even if the ceiling tile accidentally falls off.

[Installation view on Dry Wall Ceilings]

Caution

Only install the Tile Bar Bridge on ceiling frames that can structurally support the weight of the speaker(s).
