How to solve the problem when the EAS RF anti-theft system doesn'twork? [Bohang]
In order to avoid the economic loss caused by the theft of goods in the store, many businesses have installed anti-theft devices for their stores. Due to the low cost and low price of the EAS RF anti-theft system, many small supermarkets, clothing stores, and stationery stores can see the shadow of the EAS RF anti-theft system everywhere. However, the anti-interference of the EAS RF anti-theft system is not very strong, so some troubles will inevitably occur in the work. How to solve the problem when the EAS RF anti-theft system works?
1. There is interference at the scene, but no interference source can be found or interference cannot be eliminated.
Some shopping malls have a lot of interference sources. When this happens in the EAS RF anti-theft system, the solution is to first select the location where the EAS RF anti-theft system is installed. The installation site should avoid metal railings and metal doors to avoid interference. The second is to increase the sensitivity. Now the sensitivity of many EAS RF anti-theft systems on the market is adjustable. The sensitivity of the EAS RF anti-theft system is increased, which can greatly improve the anti-interference ability of the EAS RF anti-theft system.
2. EAS RF anti-theft system alarm delay
Increase or decrease the center frequency of the launch pad, increase the swept width of the launch pad, adjust the receiver board to manual state, and use a better quality security tag.
3. Problems when working online
The EAS RF anti-theft system includes an antenna power supply, an antenna frame, and a motherboard. Generally speaking, the antenna frame has been strictly tested at the factory, and is usually not damaged by transportation or the like, and the power supply and the motherboard are different, so first we have to check Whether the connector plug and jumper cap of the motherboard are loose or fall off. After checking the problem, replace the motherboard and the power supply to check it. If there are multiple antennas on the site, change the good motherboard and the bad motherboard. Constant testing results in poor alarm results.
