There have been several cases where we have discovered
loose screw connections between loudspeakers and
attachment braces / brackets.
Functional recommendations
• Loudspeakers must be fastened to the brackets in a manner that permits adequate locking of attachment bolts.
• Loudspeakers must be placed where they are not at risk of being hit by mobile equipment.
• If there is a risk of being hit by mobile equipment,
loudspeakers must either be protected by reinforced braces or equipped with a safety wire.
• Calculations must have been made and be available for attachment points and securing devices, relating to the relevant fall energies.
• User manuals / instructions must provide guidelines for the correct mounting of securing devices.
• User manuals / instructions must also provide guidelines for necessary maintenance and inspection of securing devices.
