Brief description of how to replace the Fingerprint Scanner battery

As an emerging product, Fingerprint Scanner have slowly become popular. Everyone knows that Fingerprint Scanner, as electronic products, require electricity to be used. So how is the Fingerprint Scanner powered? How to access the Fingerprint Scanner when it is out of power? The following is a brief The editor will introduce it to you.

The Fingerprint Scanner is a type of electronic lock, and the driving energy of the Fingerprint Scanner is naturally electricity. Currently, the power supply method of electronic lock products including Fingerprint Scanner on the market is a built-in power supply. The power supply standard is 6V. Therefore, all major Fingerprint Scanner products are powered by four AA dry batteries. Some Fingerprint Scanner products can be installed in battery boxes. 8 batteries, but half are spares. After the Fingerprint Scanner completes fingerprint recognition, the drive motor rotates to eject/retract the lock tongue/lock point, so four dry batteries can provide 8-12 months of power.
Since the power supply of the Fingerprint Scanner is a dry battery, many users are worried about what to do if the power supply in the Fingerprint Scanner is exhausted. In this case, Fingerprint Scanner manufacturers and Fingerprint Recognition Time Attendance will naturally take precautions and Make several more appropriate solutions. 1. When the battery of the user's Fingerprint Scanner is too low, the Fingerprint Scanner will issue a prompt in time to remind the user to replace the battery quickly. For example, the Fingerprint Scanner will issue a low-voltage alarm every time the user uses the Fingerprint Scanner when the Fingerprint Scanner has 50 openings left to use power, until the user replaces the battery or the battery is completely exhausted; second, even if the Fingerprint Scanner If the internal battery is completely exhausted, the user can buy a 9V battery in a supermarket store and temporarily connect it to an external power supply to facilitate the user to open the door. Third, when the Fingerprint Scanner runs out of power and an external power supply cannot be purchased, if you have a mechanical key, you can use the mechanical key to temporarily open the door.
Fingerprint Scanner produced in accordance with Fingerprint Recognition Time Attendance industry standards should be equipped with an additional emergency power supply interface, which can be externally powered by a 9V laminated battery. Both batteries are available in supermarkets.
Fingerprint Scanner and Fingerprint Recognition Time Attendance are becoming more and more rich in functions, and their power consumption is also increasing. Some people will wonder why not directly connect to household circuits for power supply. This external power supply seems feasible, but it is not a one-time solution, and it can be achieved It's very troublesome. Firstly, if the Fingerprint Scanner needs to use 220V household electricity, a transformer module needs to be added to the Fingerprint Scanner, and the circuit of the Fingerprint Scanner needs to be re-involved; secondly, the Fingerprint Scanner is installed on the door, and the door needs to be movable. The Fingerprint Scanner is connected to an external household appliance, so how to connect the wiring to the Fingerprint Scanner becomes a problem. Poor wiring will also affect the appearance of the overall door lock. Door locks are something that family members must come into contact with every day. Access to household electricity requires safety issues such as preventing leakage. This not only poses certain safety risks to users, but also significantly increases the cost of using Fingerprint Scanner.
