1. Introduction
Dear Customer,
We want to thank you for purchasing this antenna module
With this unit you have acquired a product built to the latest state of engineering. Its operation is simple and easily
understood. Nevertheless please read this Operation Manual carefully for optimum utilization of all of its features.
2. Intended Use
The intended use of this antenna module 2002 ANT is to read data from transponders into RF reader modules according to the technical notes in this user guide.
Any use other than the one pointed out above is not admissible.
Design and construction of this Module correspond to all European and national requirements for Electro Magnetic
Compatibility (EMC). The unit carries the CE-Sign, the conformity has been proven. All appropriate commentaries and
records are in the possession of the manufacturer.
3. Safety Instructions
Important Informations on the Reader Module:
• In conjunction with the Reader Module the Antenna builds a tank circuit creating high voltage at the antenna terminals. Please avoid any contact to these antenna terminals during operation of the Reader and especially keep
children at a safe distance from the device.
• The RF Reader Family has not been designed to safely lock or secure doors. During prolonged absence from any
room made accessible by a Reader the door must therefore further be locked by means of the original key.
• In order to guarantee sabotage safe operation do in any case mount the Reader’s electronic circuit - unreachable
for non-authorized persons - inside of the building.
• We cannot take liability for damages caused by improper and/or careless handling of RF Reader products.
For use with the RF Readers specific Transponders suitable for these Readers are necessary.
Notes on Installation of the Reader Modules:
• The Modules are considered Reading and Controlling Devices of Mode of Operation Typ 1 according to EN 60730
(VDE 0631).
• When installing the Reader and Antenna Modules ensure a clean and dry environment.
• The individual Modules must be dry and free of dust.
• For protection of the power supply line use a slow-acting 2.5 A fuse.
• In case a bell transformer is used to provide the necessary power to the Reader Modules of the RF Reader it has
to correspond with the requirements according to EN 61558-2-8 (DIN VDE 0570 Part 2-8: Special requirements
for bell and ringer transformers).
•
Notes on Placing and Mounting the Reader Modules:
When mounting Reader and Antenna the following guidelines have to be observed:
• Metallic objects must not be placed between Antenna and Transponder.
• The Antenna should be mounted on non-metallic material (wood, concrete) at a minimum distance of 3 cm from
any metallic object.
• The connecting line of the Antenna must not be of any length in excess of 1.5 m. Otherwise the reading distance
stated for the Reader Modules in Section 12. Technical Specifications cannot be guaranteed.
• The connecting line of the Antenna must not be mounted in the immediate proximity of any other line carrying
electric current.
• Two or more connecting lines of any Antennas must not be mounted side by side.
• When mounting several RF Readers inferences of Modules among each other can be avoided if a mini-
mum distance of approximately 1 m is kept between Reading devices.
4. Device Description
The antenna module 2002 ANT is a module which is exclusively designed to be used as antenna for RF readers.
It comprises a coil embedded into a molded plastic part and a two wire connection cable with 1,5 m length.

5. Functional Description
Important Note:
The antenna builds in conjunction with the Reader Module a tank circuit creating high voltage at the antenna terminals. Please avoid any contact to these antenna terminals during operation of the Reader and
especially keep children at a safe distance from the device.
The antenna activates through its high resonance voltage a transponder which is held close enough to the antenna,
receives data from the transponder and provides the information to the RF reader module, which is able to decode the
information.
Any electrical noise (electric wires, motors, switching power supplies, fluorescent lamps, monitors, laptops, etc.)
nearby the antenna or the antenna cable may interfere with the used frequencies and disturb the proper reading of
transponders. Please avoid any of above mentioned noise sources close to the antenna module.
6. Connections
For proper connection of the two antenna wires to the RF reader module or the power module please follow the instructions in the corresponding user guide.
The antenna module can be mounted both on a wall or flush-fitting in a 60mm switch box.
Mounting on a wall can be done with two screws M3 or with the attached double sided self adhesive tape.
Please take into care that no metal parts are close by the antenna (distance > 5 cm).
If the antenna module is mounted as a sandwich assembly together with the RF reader boards, please keep a distance
of min. 2 cm between the module and the reader pcb.
The cable is fixed at the antenna module. For proper mounting on a wall one can remove the thinner part of the side
wall of the antenna. This allows to route the cable on the side of the module.
The cable (LiYY) has a length of 1,5 m with a twisted pair of 0,14 mm² wires. The length should not exceed 1,5 m as
this could reduce the reading capability of the RF reader.
Please take care of not bending the antenna module during assembly. This might break the coil or cable wires inside
the antenna module.
7. Putting into Operation
If the RF reader (with power module) and the antenna are connected properly, the reader can be put into operation..
8. Care, Maintenance and Disposal
Besides providing the specified voltage and its intended use as an antenna module for the RF reader modules the
antenna module does not require any special care or maintenance.
An antenna module that highly unexpected has become unusable must be disposed of observing all relevant legal
regulations.
9. Debugging
If all notes and regulations of this and other relevant Operation Manuals are observed correctly there should be no
unexpected malfunctions. If this nevertheless happens to be the case, please do not attempt to make any own repairs.
Return the device to your point of purchase and have it checked and possibly repaired by a qualified engineer. Opening or improper handling of the devices will invalidate any guarantee.
