circumstance. None of the information presented herein is intended as a representation
of warranty on the part of ISP Technologies. Anyone making use of this information
assumes all liability arising from such use.
All information presented in this manual is based upon materials and practices that are
most common to The United States of America and may not directly apply to other
countries because of differing material dimensions, specs, and/or local regulations.
Users in outside countries should consult with appropriate engineering and regulatory
authorities for specific guidelines.
Correct use of all flyware is required for secure system suspension. Careful calculations
should always be performed to ensure that all components are used within their working
load limits before the cabinet suspended. Never exceed the maximum load ratings.
Before hanging any speaker system, always inspect all components for cracks,
deformations, corrosion, missing, loose or damaged parts that could reduce strength
and safety of the cabinet. Do not suspend the cabinet until the proper corrective action
has been taken.
ATTACHMENT TO STRUCTURES
A licensed professional engineer must approve the placement and method of attachment
to the structure prior to the installation of any overhead object. The following
performance standards should be provided to the professional engineer for design
purposes; Uniform building code as applicable, Municipal Building code as applicable and
Seismic Code as applicable.
INSPECTION and MAINTENANCE
Suspension systems are comprised of mechanical devices and, as such, they require
regular inspection and routine maintenance to insure proper function ability. Any
suspended ISP Technologies loudspeaker must be inspected for fatigue at least once per
year. 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.
Flyware that is provided with or for any ISP Technologies loudspeakers must be
inspected for fatigue at least annually. 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.
