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

The external, autonomous ATLO-KRM-821 keypad lock is a professional access control solution, combining modern design with top-tier functionality. The device is designed to operate in harsh weather conditions, as confirmed by its high IP68 ingress protection rating. Its robust, metal housing with a narrow profile allows for installation in space-constrained locations, such as gate posts or narrow door frames.

Full programming via keypad; adding and deleting individual cards and PINs; changing user PIN; setting lock release time (door open time); resetting to default settings.
Software and configuration
The device features a built-in programming interface operated directly from the device's keypad. The device operating system allows for precise management of the 2000-user database via indexing. The administrator has the ability to configure relay operation modes, lock hold time, and define access rules (card only, code only, or both simultaneously). The system also supports a 'tamper' function that reacts to unauthorized casing opening and allows for integration with alarm systems via door-ajar signaling. The device's logic also allows for the connection of an external Wiegand reader for dual-sided control.
