Recommendations for installation

Reading module ATEUS

RF disturbance. This disturbance may come via radiation from the surroundings or via

supply cables.

Therefore it is necessary to avoid installing modules close to possible sources of

electromagnetic field, including for example computer monitors (distance at least 3 cm)

and various home and industrial appliances. It is also better to use recommended power

supply (linear) to reduce disturbance coming via the cables.

From this perspective it is also necessary to take into consideration mutual disturbing of

the reading modules – for proper functioning of modules it is necessary to keep the

distance of at least 50 cm. This distance can be negatively influenced by various metallic

constructions (in case of doubts it is recommended to carry out practical test on the spot

before the final installation).

Proper functioning and the reading distance can also be influenced by metal surfaces

close to the antenna. Such objects absorb electromagnetic field and may disturb the

antenna of the module – also in this case we recommend practical test.

It is recommended to install the chip card reader indoor on a wall, together with the door

communicator and reader's antenna. Installing the reader indoors will provide protection

against climatic conditions of the outside environment and aggression of persons trying to

break into the building. If only the antenna of the reader is located outside of the building it

will not be possible to switch the door lock without authorization. Unauthorized switch of

the lock can only be achieved by manipulating with the reader's mother board. The mother

board can be installed on the wall using installation box, which is supplied together with

the board.
