Interference Source of EAS system

1. Not independent power source.
As the electronic device is running, the public power source may affected and simultaneously generate noise to
EAS devices. So we suggest to use independent power source to run our EAS devices.

2. Lift.
Lift will generate serious noise to EAS devices. We suggest change the installation position or shorten the system
detecting distance.

3. Bad lamp.
Bad Lamp will generate to EAS devices. We suggest to replace a good one or use some materials to avoid the
interference.

4. Other Anti-theft devices.
Noise form other EAS systems in 10 meters may interfere your using EAS systems. We suggest to leave away from
other EAS systemsat least 10 meters or shorten your using EAS system detecting distance.

5. Metallic door-frame.
If the EAS devices is less than 1 meter away from the doorframe, it may generate reflection noise. We suggest install
the EAS devices away form the door-frame or change the installation position.

6. Multiple power cable.
Multiple power cable will generate noicse to EAS devices. We suggest to avoid other cable to twist with EAS cable or
metallic truss with GND.

7. Generator or electric motor.
Noise from generator or electric motor will affect system working. We suggest to be away from these generator or
electric motor or use other method to avoid interference.

8. Metallic shelf.
If the EAS devices is less than 1 meter away from the metallic shelf, it will generate reflection noise. We suggest install
the EAS sensors at least 1meter away from the metallic shelf or shorten the EAS sensor detecting distance.

9. Rectifier Lamp box.
The rectifier lamp box will generate a big disturbing magnetic field, it will interfere the EAS devices working. We suggest
to replace a good one or try other method to avoid interference caused by the lamp box.
