Fingerprint Door Lock Overview

Parameters Table and Details

Application Scenarios

Government employees can use fingerprint locks to access government offices, ensuring the security of sensitive information and facilities.
In government buildings with high - security areas, such as intelligence agencies or defense departments, fingerprint locks can provide an extra layer of protection.
For government building maintenance and cleaning staff, fingerprint locks can be used to control access to different areas of the building.
In case of a security threat or emergency in a government building, the access logs can be reviewed to identify who was in the building at the time.
When government buildings host public events or meetings, visitors can be provided with temporary fingerprint access or one - time codes.

Features and Advantages

Supports time-limited IC cards, ideal for short-term rentals or hotel use, with cards that expire after a set period.
Allows users to set the lock to “do not disturb” mode, preventing it from unlocking during specific hours (e.g., bedtime) except for authorized users.
Equipped with a built-in clock that enables accurate scheduling of access permissions and auto-lock times.
Supports remote firmware updates via the app, ensuring the lock always has the latest features and security patches.
The lock’s exterior has a vandal-resistant design, with a tough surface that resists scratches and graffiti.

Considerations for Use

Reset the lock to factory settings (using the reset button) if you encounter persistent software glitches.
If the lock makes grinding noises during operation, stop using it immediately and contact customer support—this may indicate a mechanical issue.
For low-battery warnings despite new batteries, check for corrosion in the battery compartment and clean with a dry cloth.
If the auto-lock function fails, ensure the door is closing fully and the lock’s sensors are not obstructed.
If the bolt retracts but the handle won’t turn, check for a disconnected linkage between the handle and lock mechanism.
