Introduction
You have decided in favour of a high-quality product that has been developed and manufactured with the
utmost care. Only proper, professional installation and commissioning can ensure long, reliable and fault-free
operation. This manual contains important information on commissioning and handling. Please read carefully
before putting your new Free-Control device into operation! Keep the manual in a safe place for future
reference!
This device meets the requirements of the applicable national and European regulations and is approved for
use in the EU and EFTA States. You can find the declaration of conformity, further information, application
examples, range summary and operating instructions at:
www.kopp-elektro.eu
Liability or any further claims, in particular for compensation for injury to persons or damage to property
caused by the device due to missing or faulty functions are excluded. Changes due to technical progress,
changes in standards, modified manufacturing processes or design changes are expressly reserved.
Please note the rules of electrical engineering and compliance with the technical data!
Please ensure and check that the device is switched off before beginning work.
Do not connect any devices that require supervised operation. Do not make any changes to the devices.
The radio transmission takes place on a non-exclusive, available frequency channel at 868.3 MHz. Therefore,
faults cannot be completely ruled out. However, the appropriate layout will ensure that maximum transmission
security is achieved. Not suitable for safety applications, e.g. EMERGENCY STOP, EMERGENCY CALL.
Notes on radio operation
Free-Control can be used anywhere that the expansion or extension of existing installations is impossible or
very difficult. Therefore, the possible applications of the Free-Control radio system are extremely versatile,
right up to Smart Home. The specification for the radio range is always a free field value and is only to be seen
as a reference value.
Signal reduction and transmission range depend on the following:
1. the material composition to be penetrated (wood, masonry, glass, etc.)
2. the material thickness to be penetrated (wall thickness)
3. the climatic conditions (dry environment, rain, snow, etc.)
4. existing local radio interference (possible local radio masts, in-house wireless routers, etc.)
5. any existing radio dead spots (receiver shadowed by areas that are impenetrable to radio)
The above factors can change unexpectedly and significantly influence the transmission range.
Reduction of the radio transmission signal in % (reference values)
rain, snow
= approx. 60 - 100%
metal, metal mesh, aluminium cladding
= approx. 90%
reinforced concrete
= approx. 75%
brick, press boards
= approx. 30%
wood, plaster, uncoated glass
= approx. 10%
