Safety

1.1

Suspension

!

Warning!

Suspending any object is potentially dangerous and should only be attempted by individuals
who have thorough knowledge of the techniques and regulations of suspending objects
overhead. Bosch strongly recommends all loudspeakers be suspended taking into account all
current national, federal, state, and local laws and regulations. It is the responsibility of the
installer to ensure all loudspeakers are safely installed in accordance with all such
requirements. When loudspeakers are suspended, Bosch strongly recommends the system be
inspected at least once per year or as laws and regulations require. If any sign of weakness or
damage is detected, remedial action should be taken immediately. The user is responsible for
making sure the wall, ceiling, or structure is capable of supporting all objects suspended
overhead. Any hardware used to suspend a loudspeaker not associated with Bosch is the
responsibility of others.

Safety point

As an added safety measure, it is suggested the user install an extra suspension point back to
the building structural supports. This safety point should have as little slack as possible (less
than 1-inch is preferable).
