1.5 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 or pole mounting any speaker system, always inspect

all components (enclosure, suspension frames or brackets, pins, eyebolts, etc.) for cracks, deformations, corrosion, or

missing/loose/damaged parts that could reduce strength and safety of the array. Do not suspend or pole mount 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, de-lamination, or any other condition that may decrease the

strength of the loudspeaker enclosure.

Accessory suspension hardware provided with or for VTX 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.

parts and components.
