RIGGING / SUSPENSION AND SAFETY
TERMINOLOGY:
The terms “rigging", “flying" and “suspension" are often used
interchangeably to describe the installation of loudspeaker systems above ground level.
None of these terms pertain to, or attempt to describe, the actual method that is used
(cables, yokes, chains, etc.).
DANGER:
The loudspeakers described in this manual are designed and intended
to be suspended using a variety of rigging hardware, means, and methods. It is
essential that all installation work involving the suspension of these loudspeaker
products be performed by competent, knowledgeable persons who understand safe
rigging practices. Severe injury and/or loss of life may occur if these products are
improperly suspended.
DANGER:
All rigging fittings and inserts must remain sealed with the included
hardware or they must be fitted with properly rated optional mounting hardware.
Any missing fasteners will compromise the weather resistance of the enclosure.
COMMUNITY RIGGING HARDWARE WARRANTY:
Community warrants that its loudspeaker systems and its optional mounting and
rigging hardware have been carefully designed and tested. Community loudspeakers
may be safely suspended when each loudspeaker model is suspended with Community-
manufactured mounting and rigging brackets or yokes specifically designed for use
with that particular model of loudspeaker. This warranty applies only for use under
normal environmental conditions, and when all loudspeakers, component parts, yokes
and hardware are assembled and installed in strict accordance with Community’s
installation guidelines contained herein. Beyond this, Community assumes no further
or extended responsibility or liability, in any way or by any means whatsoever. It is the
responsibility of the installer to insure that safe installation practices are followed, and
that such practices are in accordance with any and all local, state, federal, or other, codes,
conditions, and regulations that may apply to, or govern the practice of, rigging, mounting,
and construction work in the relevant geographic territory. Any modifications made to
any parts or materials manufactured or supplied by Community shall immediately void
all pledges of warranty or surety, related in any way to the safe use of those parts and
materials.
WARNING
NON-COMMUNITY RIGGING HARDWARE:
Non-Community hardware used for rigging an R SERIES loudspeaker must be
certified by the supplier for such use and must be properly rated for safety.

IMPORTANT NOTES ON
RIGGING LOUDSPEAKERS
There are three areas of responsibility
for rigging loudspeakers. The first is the
building structure. Always consult with the
building architect or structural engineer to
assure the ability of the structure to support
the loudspeaker system. The second
area of responsibility is the loudspeaker
itself. Community certifies its loudspeaker
systems and rigging accessories for
suspension when they are properly
installed according to our published
guidelines. The third area of responsibility
is everything between the loudspeaker
and the building structure and the actual
process of installation. The installing
contractor assumes this responsibility.
Loudspeaker rigging should be performed
only by certified rigging professionals using
certified rigging hardware chosen for the
specific application. Prior to installation,
the contractor should present a rigging
plan, with drawing and detailed parts list,
to a licensed structural engineer (P.E.) or
architect for written approval.
WARNING:
R SERIES rigging fittings
are rated at a Working Load Limit of
100 lbs (45.4kg) with a 10:1
safety
margin. No single rigging fitting should
ever be subjected to a load that is greater
than
100 lb
s. Failure to heed this warning
could result in injury or death!
ACCEPTABLE MOUNTING POINT
LOADING
T
he mounting points should always be
used so that either shear force is applied
perpendicular to the direction of and in
tight proximity to the mounting hole, or
tension force is applied perpendicular to
the enclosure surface. See
Figure 1
at left.
DANGER:
Use the mounting points
only as described above. Do not use
them in such a way as to apply
sideways leverage to them. Failure to
follow this instruction could result in
immediate failure of the mounting points
resulting in damage to the loudspeaker and
serious injury or death to personnel.
