Access control card reader we have long believed that good door not only need to lightning protection, moistureproof, prevent high and low temperature, also need to have a wide voltage, meter, mistake proofing function. title="nantong huanli"

in several projects above, meter, prevent wrong functionality is don’t have a lot of products.This function can effectively avoid because of negligence wrong line, pick up the line, have the effect of protection door.If the product does not have this function, in the case of wrong line, equipment they may damage, and in this case, many manufacturers are listed as think error caused damage, is not warranty.

good product will fully consider the user’s use, generally have meter, prevent wrong function of entrance guard device can make connection is more convenient and accurate, and made the construction is simple, can accelerate the process of the project, so the selection of access control equipment testing, this feature should be listed as one of the measurements.

so how can we test this function?Professional circuit protection circuit on the board to look at it.Laypeople can pass after power on, wrong, reverse connection port, and then in the correct connection, if the equipment can run normally, meter, mistake proofing is the device port protection performance is good.
