The main advantage of this device is its autonomy – the lock does not require an external controller for proper operation, which significantly simplifies installation and reduces system costs. Users can choose from three identification methods: via 125kHz Unique RFID proximity card, by entering an individual PIN code, or a combination of both methods, which greatly increases the security level of the protected site.
The lock offers a rich set of additional features, such as blue keypad backlighting for easier operation after dark, a built-in doorbell button, and acoustic and visual operating status indicators. The system can store up to 2000 users, making it an ideal solution for single-family homes, as well as small offices or industrial facilities. The device also supports advanced alarm functions, including an open door alarm, which prevents unauthorized access through ajar entrances. Thanks to the support for an exit button and a door contact sensor, the ATLO-KRM-821 provides a complete access control point.

Software and configuration
The device features a built-in programming interface operated directly from the device's keypad. The device's operating system allows for precise management of the 2000-user database via indexing. The administrator can configure relay operating modes, bolt hold time, and define access rules (card only, code only, or both simultaneously). The system also supports a 'tamper' function that reacts to unauthorized housing opening and allows for integration with an alarm system by signaling a door left ajar. The device logic also enables the connection of an external Wiegand reader for dual-sided control.
