Description

The DXSL42 combines biometric intelligence with secure, app-enabled convenience. Its fingerprint sensor sits directly on the handle, allowing one-step unlocking without additional input; it is perfect for children, the elderly, or anyone on the move.

Designed for high-traffic residential or interior doors, this model features an annular LED indicator ring that clearly communicates the lock’s status. The fingerprint algorithm learns over time for quicker, more accurate recognition. Users can manage access rights, generate timed passcodes, and monitor activity via the mobile app.

With its motorised mortice and protected internal cylinder, the DXSL42 resists tampering, even if the front panel is compromised. An anti-peep PIN pad and idle handle mode prevent forced entry. When locked, the handle turns freely without engaging the latch, protecting the mechanism.

If the room is double-locked from the inside, only an administrator can override the lock, safeguarding privacy and preventing accidental lock-ins.

This lock is ideal for modern homes, flats, rentals, or offices that require tiered access and a balance between privacy, control, and design.
