1. All the finished anti-theft door installation in the finished door and window installation, the material price adjustment, remember to convert the price of a fan into a square meter price. This door must be sold on a fan.
The inductance parameters in the electronic key have changed, or the inductance parameters in the lock have changed or broken (if everyone can not use this situation), you can only find the seller to change one, this kind of door has a password, with the password can also be opened, you can set a password for your own family on the extension at home, the setting method to ask the property manager or the manufacturer or seller of the door, you can also ask the neighbor, generally 12-18 years old children have such a password, There must also be a public password.
It shouldn't be a big problem, but it should be changed according to the voltage and current of your system, otherwise it is easy to cause the system to be mismatched and unstable, and the battery power loss is too fast and too large, which is easy to fail, so think twice.
Generally, no, because mobile phone chargers are generally 5 volts and so on, but the anti-theft door battery is usually 9 volts.
There are more anti-theft words, and the difference is here, the former needs to be made according to the standards of anti-theft doors, such as materials, locks, etc. But the latter is not needed, only the electronic gate is required.
