The main advantage of the device is its autonomy – the lock does not require an external controller to function properly, which significantly simplifies installation and reduces system costs. Users can choose from three identification methods: via a 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 for easy operation after dark, a built-in doorbell button, and both acoustic and visual 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' signal, which prevents unauthorized access through improperly closed doors. With support for an exit button and a door contact sensor, the ATLO-KRM-821 constitutes a complete access control point.

The outdoor, autonomous ATLO-KRM-821 keypad is a professional access control solution that combines 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 areas, such as fence posts or narrow door frames.

Card support standard
Unique EM 125kHz - standard RFID technology allowing data reading via radio waves at a 125 kHz carrier frequency without the need for optical visibility.
Card reading range
Maximum up to 6 cm (depending on the transponder used).
Autonomous operation
Yes - the device has built-in memory and control logic; no computer or external controllers required.
System capacity
Support for up to 2000 users (each with a unique assigned code or card).
User interface
Built-in numeric keypad with blue LED backlighting; doorbell button.
Signaling
Acoustic (buzzer) and visual (LED status indicators).
Power supply
12 V DC ± 10% (stabilized DC power supply required).
Power consumption

Control outputs
NO/NC relay output with 3 A / 24 V DC contact rating.
Administrator functions
Full programming via the keypad; adding and deleting individual cards and PINs; changing user PIN; setting lock release time (door open time); reset to factory defaults.
Software and configuration
The device has 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 through indexing. The administrator can configure the relay operating mode, 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 opening of the housing and allows for integration with an alarm system through the notification of a door left ajar. The device's logic also allows for the connection of an external Wiegand reader for dual-sided control.
Security and environment
