WARNING
Indicates a potentially hazardous situation which, if
mishandled, could result in moderate or minor personal
injury, and/or property damage.
CAUTION
• Leave the installation to your TOA dealer because the installation requires expert
knowledge. Improper installation may cause the speaker to fall, resulting in personal injury
and/or property damage.
• Install the mounting hardware in a location that can structurally support the weight of the
mounting hardware and the speaker. Doing otherwise may result in the speaker 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.
• Tighten each screw securely. Ensure that the unit has no loose joints after installation to
prevent accidents that could result in personal injury.
• Use the specified speaker in combination. Doing otherwise may cause the speaker or
component to fall off, resulting in personal injury.
• Avoid touching the unit's sharp metal edge to prevent injury.
2. GENERAL DESCRIPTION
TOA's HY-TB1 Tile Bar Bridge is a 603 mm (23 47/64") long support frame (set of 2 rails)
designed to provide secure support for flush-mounted ceiling speakers while preventing the
speaker's weight from being directly applied to the ceiling panels. Its support rails are
designed to act as mounts for the ceiling reinforcement ring supplied with each speaker.
Before installation, a qualified architect or engineer should first determine whether the ceiling
frames and panels are strong enough to withstand the added weight of ceiling speakers.
Refer to the speaker's instruction manual for information.
