Fbt Myra 214L, Manual

Page: 48 / 92

WARNING
MYRA sound speaker must be installed using the flying
accessories described in this manual and following the
special assembly instruc ons by qualified staff only, strictly
complying with the current regula ons and safety standards
in farce in the country of installa on.
FBT flying accessories are manufactured for their exclusive
use with FBT MYRA system and have not been designed for
being used with any other speaker or device.
Any possible elements of the ceiling, floor or further
supports where MYRA system is to be installed shall be able
to safety bear the load.
Always make sure that all a achment and fastening systems
are of the appropriate size and load capacity
Besides the main suspension system, all flying speakers in
theatres, indoor stadiums or in several other work and/or
leisure facili es shall be provided with an addi onal
independent safety system with the adequate load capacity.
Only steel cables and chains with cer fied load capacity can
be used as an addi onal safety device.
Special a en on was paid to the selec on of the materials and
manufacturing so as to permit high safely levels. The staff in
charge of hanging the array system must be skilled and
qualified; the installer/user will be responsible of ascertaining
limits and li ing procedures for the structures to which the
array will be a ached. An improper use of the array suspension
system may cause major damage to person and things.
FBT accepts no responsability for any damage to people
or objects if these instruc ons are not complied with or
if the safety factor of all elements related to system
suspension are not properly checked.
MYRA system may be both flown and laid on the ground.
System moun ng type depends on the acous c environment
that needs being created and on the imposed assembly
constraints. In the majority of common applica ons it is be er
to hang the system since this guarantees a more homogeneous
coverage of the listening area. Every me the area for sound
reproduc on is located at a single level below an available
a achment point and extends over a certain lenght, system
suspension is the best solu on because it permits to be er
distribute the sound pressure over the whole area where sound
is reproduced.
During installa on, make sure that system bearing framework
is included in the calcula on of the total weight, as well as the
flybar, hoist chain, motors, cables and any addi onal weight.
Should the above safety regula ons and calculta ons of
the overall weight fail to be complied with, FBT
Ele ronica will not liable for any damages to persons
and things.
In "flying" mode the accessories have been designed to
suspend up to 24 MYRA 214L modules and up to 12
MYRA 218S modules.
• Never use the handles or other elements of the
speaker to suspend the modules.
Perform all the addi onal fastening techniques
necessary for safe and stable use of the line array,
also considering any atmospheric phenomena to
which it may be subjected.
In "ground-stack" mode, maximum 4 MYRA 214L
modules and 2 MYRA 218S modules
straps.
Place the system on a flat and non-slippery surface;
in the case of a support surface that has a slight
inclina on, it is necessary to adequately secure the
installa on with suitable mechanical means or
MYRA Rigging Safety Calculator
FBT Ele ronica makes available a so ware for calcula ng the
safety factor according to the configura on used:
For the calcula on of the safety coefficient for use and the
regulatory framework rela ng to the design criteria for steel
structures, the following reference technical standards were
observed:
EN 13814 - Fairground and amusement park machinery
and structures. Safety Industry Standards.
EN 1991-1-1 - Eurocode 1 - Basis of structural design and
ac on on structures.
EN 1990 - Eurocode 0 - Principles and requirements for the
safety, opera on and durability of structures
EN 1993-1-1 - Eurocode 3 - Design of steel structures.
