B.3. SUSPENDED FROM CEILING OR TRUSS ("flown" installation)
DANGER: risk of injury: flown installation requires extensive experience, like calculating working load
limits, knowledge of installation materials, and periodic safety inspection of all installation material and
the flown product. If you lack such qualifications, do not attempt the installation yourself. Improper
installation can result in injury of people.
As a preparation for flown installation, attach eyebolts to the mounting points in the speaker cabinet as
per below drawing. In the further course of the installation, make sure that:
-
The product is installed out of reach of people and outside areas where persons may walk by or be
seated.
-
The installation area can hold a minimum point load of 10 times the device's weight
-
The installation is secured with an appropriate safety cable where necessary. Always use a certified
safety cable according to DIN56927 that can hold 12 times the weight of the device when installing the
unit. This secondary safety attachment should be installed in a way that no part of the installation can
drop more than 20cm if the main attachment fails.
-
The installation place is free from unwanted persons during installation, de-installation or servicing.
-
The safety-relating and machine-technical installations are approved by an expert before using them for
the first time.
-
The installation is re-inspected every year
-
The cooling requirements are met (if any). Note that warm air is ascending, making the area below a
rooms' ceiling potentially warmer than lower locations.
