Safety

!

Warning!

Suspending any object is potentially dangerous and should only be attempted by individuals

who have a 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.

!

Caution!

The seismic tab (auxiliary support ring) is not intended for primary suspension of the

loudspeaker. The seismic tab should only be used as a secondary safety point.
