Analysis for common troubles of anti-theft security EAS system[BOHANG]

As we all know,nowadays with the development of the economy,people’s ideas are getting more and more advanced,the owner’s awareness of anti-theft is getting stronger and stronger,they know to choose to install anti-theft security EAS system to protect their stores.Some small shops are only one meter width of the door,it just need to install one piece anti-theft security EAS system,when there are some troubles,it is easy to check and troubleshoot.But for some big store,there are 3-10 pieces anti-theft security EAS system,how to check and troubleshoot,it is a little complex.Today BOHANG electronics will introduce some methods for you,please see as followed.

If there are three anti-theft security EAS system installed on site, and one of them launched, but the other two of them are not normal.(there are no alarm and self-chirps).Two methods,one is that use EAS to detect transmitting antennas, check them many times, if no frequency, to check the Sync cable or main and slave jumpers.The second method is to use EAS to detect transmitting antennas, check them many times, if frequency sometimes no, then you can judge it is the launch circuit board fault.If it is used online, it needs to detect the main transmitting circuit board, generally the main transmitting board is bad.

If there are 4 or more anti-theft security EAS system installed on site, working online, all the devices are not working (RF)? Three method,one is to detect the power indicator and detect the output of each power supply, especially the main transmit power. The second method is to use EAS to detect the main transmitting antenna to see if the transmitting frequency is normal, including the center frequency, modulation frequency, sweep width and so on. Three is if the main transmitting board is broken, replace it with the standby board directly; if there is no spare board, the main and sub-transmitting board mode can be replaced (that is, the main jump is paired, the secondary jumps into the main), and the online line is adjusted. Or directly adjust the transmitter board and the receiver board, and the debugging can be normal.
