Hello, I got a batch of FC-185M card readers from your company, there are multiple card readers that can sometimes read the card number, sometimes can not read the card number, what is the cause? How should it be solved?
Hello, first of all thanks for using our access control products
Step 1: Check whether the power supply is working properly.
Step 2: Check whether the access control card reader is damaged.
Step 3: Check whether there is strong magnetic interference around the access control card reader, it is recommended that the card reader is 2-3 cm high with a wooden block.
If the above steps are eliminated, the card reader still cannot read the card, the following fault causes can be determined: The card reader device will generate some static electricity when used for a period of time, the accumulation of static electricity over a long period of time causes excessive power consumption, the shorter the use time, such a problem indicates that the card reader is aging too fast.
Solve the problem: Before installation, choose a special power supply with good quality and gated power, if this happens after use, power the electric lock and the card reader separately, and add a power supply to the card reader separately.
Slow card reading speed of access control card reader, the troubleshooting problems of the proximity of the sensing distance are as follows:
Step 1: Whether the card reader is installed on the metal door
Step 2: Whether to swipe in and out, such as swiping in and out to see the distance between the two card readers.
Cause of failure: If the card reader is installed on a metal door, because metal has a shielding function, part of the radio waves emitted by the card reader is shielded by the metal, if you enter and exit the card, the same problem will occur if the two card readers are installed too close, the two card readers emit radio waves at the same time, and the mutual interference of the radio waves will cause the card reading to be slow.
