2. Why LOS?
Standard-Ringschleifenanlagen erzeugen ein magnetisches Feld, welches in der Regel die »Kern-Versorgungs-
fläche« überschreitet. Dieser horizontal und vertikal wirkende »Overspill« kann drei bis vier Ringschleifengrößen
weit entfernt noch hörbar sein. Das schränkt den Einsatz dieser Technik ein. Low-Overspill-Systeme (LOS), qua-
lifiziert konfektioniert und konfiguriert, verringern den Overspill erheblich und ermöglichen so den Betrieb von
Ringschleifenanlagen in direkt benachbarten Räumen.
Das
PROLOOP LOS
ist ein komplettes System für den Betrieb von Low-Overspill-Anlagen. Es beinhaltet die kom-
plette erforderliche Elektronik in einem Gehäuse.
2.1 LOS induction loops
The optimal designs and configurations are always dependent on the venue details, i.e. the floor plans and the
sizes of the rooms serviced, the number of internal induction loops and the demands made on low overspill.
To determine the corresponding values for the »tailored« low-overspill layout and the optimal level adjustments
in each case, it is necessary to use complicated calculation and installation methods. That’s why we recommend
that you use the services provided by HUMANTECHNIK. We support architects, technicians and installation ex-
perts qualified in the planning of LOS installations.
3. Installation notes
This device operates with a dangerous voltage of 230 V. Never att-
empt to open the device yourself and never insert anything into the
air vents! You could receive a severe electrical shock!
IMPORTANT INFORMATION
When installing the induction loop amplifier, make sure that the air vents on
the front and rear panels are not covered or blocked in any way.
It is normal for the amplifier to become warm while it is in operation. It is
important that the ventilation of the device is not impeded in any way. If the
incoming air supply is limited for some reason, it will be necessary to supply
forced cooling.
Make sure that the amplifier is securely mounted and cannot slip or fall.
To prevent damage to the inner components, do not insert any screws or drill
any holes into the device housing.
Make sure that the voltage indicated on the rear panel of the device is the
same as your local voltage.
All connections should by made by a qualified technician only and only when
the amplifier is switched off.
