The solution for the high frequency manipulations on your note readers in your change machine.
When connected, the machine is directly protected against high frequency fraud. Should there be a fraud attempt, then immediately the voltage of the note acceptor removed, all credit lines are closed, the alarm goes off (if siren is connected) and on the Anti-Fraud board, the red LED is on.
The Anti-Fraud board remains in alarm until the machine is turned off. Only when the machine least 10 seconds off and then powered on again, the alarm will be reset.
Adjustments (standard is not required) :
You can set the sensitivity by means turning the potentiometer on the Anti-Fraud board. The center position is standard, less sensitive to the left and to the right sensitive.
Note: The setting only change when electric interfering elements around the exchanger, causing the alarm to sound spontaneous (flashing fluorescent tubes).
