EAS Intelligent 8.2MHz automatic EAS Electronic boards anti- shoplifting security alarm control board(E-3920) 1.Feature:   1. Processor: Analog   2. Center frequency: 8.2MHz/10MHZ 3. Bandwidth: 900KHZ 4. Scan rate: 150mhz, 160mhz, 170mhz, or 180mHz 5. Power: 24V DC, 2A; 6. Size: 19.2*.12cm (TX); 19.2*12cm (RX) 7. Weight: 0.60kgs/set 8. Packing: 0.60kgs, 22*18*5.5cm   8. Alarm volume: high, middle, or low   9. Application: used for all kinds of EAS antenna   10. Service: provide design & manufacture   11. Automatic increase sensitivity and Anti environment interference     1.Using advanced digital technology to perform signal processing,which is stong anti-interference.   2.Modulating frequency to transmitter and receiver correspondingly ,which strengthened the anti-interference ability to stagger the frequency in the complex environment   3.Increase sensitivity automatically adjust function,No need debug   4.Increase still tag exclude function.When there is still have some tag inside the detect area,the antenna will exclude this signal;then other tags pass the area ,the antenna still work properly.   5.Increase the power protection function,if you made mistake when you connect the power's positive and negative,will not cause any damage to the motherboard and power,power error indication red light,Re properly connect the power supply will be able to work properly   Unique:       1.Symmety frequency for TX and RX;                                                                                                                             2.Anti interference for the same frequency;                                                                                                                     3.Automatic/manual sensitivity adjust                                                                                                                             4.Twice distinguish for tag (when system detect first tag, it will alarm,after 3-4second don't move tag,the system won't detect this tag again,it will continue detect another tag.          

Standard install distance:
4X4 soft label	110-130cm
Mini hard tag	130-160cm
R50 hard tag	160-180cm
Large hard tag	190-220cm

      Adjustment Methods:   Reduce the install distance between the antenna.   To swap the position of the transmitter and the receiver.   Adjust the mounting position to avoid the interference source   Eliminate sources of interference   Sources of interference type:   The equipment is too close to the wall (the wall have wires inside)   Near the equipment have some wires in full rolls,such as lanterns, Christmas trees, etc.   The equipment is too close to the electrical equipment,such as Distribution cabinet, High-voltage spotlights,etc.   The RF label is too close to the equipmentheequipment is too close to some large meta object or metal railing,shopping t,metal cashier     Technical Environmental   Operating temperature: 0°C to 40°C   Storage temperature: -40°C to 60°C   Humidity: 90% non-condensing      Sketch map                   Shenzhen Eant Digital Tech Co., Ltd., (http:// www.  szeant.  com)located in Shenzhen City, China, is a specialty Electronic Article Surveillance (EAS) product company focusing on the production of innovative EAS products for Chinese and overseas markets.
