How to deal with daily faults of the anti-theft security EAS system[BOAHNG]

 

In order to protect the goods of the store,many shopkeepers have installed anti-theft security EAS system for their stores.But sometimes there are some little troubles for the anti-theft security EAS system,it does not work well.At this time,maybe someone will say: If you encounter problems, you can find after sales to solve the problem.However if every small problems,you all let the after sales to solve,the maintenance costs can be very high,it will increase the sales cost and reduce your profit.So we need to learn some knowledge of that how to deal with the daily faults of the anti-theft security EAS system.

For RF anti-theft security EAS system,general fault detection process as followed,please see it clearly.Use multimeter and Check whether the power supply voltage is normal or not,the voltage is 24V - 25V without load, and the minimum cannot be lower than 22.5 V;The voltage of the load is 24V - 25V, and the minimum cannot be lower than 22.5 V;If the voltage change a lot,when the voltage with load and without load, the power supply is not enough or the circuit board has a short circuit. The voltage is too high and too low are all the power failure, it can be repaired on site, if not, change the power supply.

a) circuit board short circuit judge: measure the resistance value, if the resistance is small (close to 0 Ω),that is the circuit board fault, repair on-site, if not,change the circuit board.

b) If all above tests are normal,check the sensitivity of circuit board.

How to determine whether the interference source, is the radio wave emitted by other equipment(active interference);or the radio waves emitted by the device itself are reflected back by other objects (passive interference)?switched off the transmitting signal (unplug the transmitting antenna), if the yellow interference indicator do not change,it is active interference.otherwise, if the yellow indicator reduced or completely does not working, it is passive interference.

After listening the introducing the knowledge of the methods from BOHANG electronics,now do you know how to deal with daily faults of the anti-theft security EAS system.Learning these,you can save much cost for your store.
