2.5 - INSPECTION AND MAINTENANCE
Suspension systems are comprised of mechanical devices and, as such, they require regular
inspection and routine maintenance to ensure proper functionality. Before suspending any
speaker system, always inspect all components (enclosure, suspension frames or brackets,
eyebolts, etc.) for cracks, deformations, corrosion or missing/loose/damaged parts that
could reduce strength and safety of the array. Do not suspend the speaker until the proper
corrective action has been taken.
Installed systems should be inspected at least annually. The inspection shall include a visual survey
of all corners and load-bearing surfaces for signs of cracking, water damage, delamination or any
other condition that may decrease the strength of the loudspeaker enclosure.
Accessory suspension hardware provided with or for VLA-C systems must be inspected for
fatigue at least annually or as required by local ordinance. The inspection shall include a visual
survey of the material for signs of corrosion, bending or any other condition that may decrease
the strength of the fastener. Additionally, any eyebolts shall be checked for possible spin-out of
the enclosure.
For all other hardware and fittings, refer to the hardware manufacturer’s inspection and
maintenance guidelines for process .
