One of the key advantages of the device is the built-in, aesthetic blue key backlight, which makes operating the lock after dark or in poorly lit corridors extremely intuitive and comfortable. The product offers a range of advanced software features, including acoustic and visual signaling confirming every operation, as well as an open-door warning system. Integration with an additional reader from the ATLO-R series allows for the creation of full, two-sided access control at a single access point. The system administrator has full freedom in managing the database of cards and PIN codes – from the keypad, they can instantly add new users, delete lost cards, or change the lock release time. The NO/NC relay output ensures full compatibility with almost every electric strike, electromagnetic lock, or gate drive available on the market. An additional, extremely practical feature is the presence of a dedicated doorbell button, which allows integrating the doorbell function directly into the access control panel, saving time and costs of installing additional wiring. The device is designed to operate in extreme temperature conditions, from -45 to 60 degrees Celsius, which proves the highest quality of the electronic components used.

This modern and highly reliable standalone keypad lock is an ideal solution for access control systems requiring a high level of security and user convenience. The device combines the function of a precise keypad with an advanced proximity card reader operating in the common Unique 125kHz standard. This combination allows for flexible access management to various rooms – from offices and warehouses to private properties and apartments. The robust metal housing with an IP40 ingress protection rating guarantees not only high resistance to mechanical damage and sabotage attempts but also maintains an aesthetic appearance for many years of intensive use. The lock allows for programming up to 2000 independent users, making it an extremely versatile tool for both micro-enterprises and larger industrial facilities.

Identification standard
The device supports proximity cards and key fobs in the Unique EM 125kHz standard. This is RFID technology enabling contactless data reading using low-frequency radio waves, which ensures high operational stability and low cost of access media.
Reading range
The maximum card reading range is up to 6 cm, which allows for convenient use of the device even through a wallet or handbag in most typical installation scenarios.
System capacity
The lock has a built-in memory allowing for the storage of up to 2000 indexed users. Each user can have an assigned card and a unique PIN code.
Communication interface
The device uses the Wiegand 26 protocol, which is a standard in security systems. This allows for the connection of an external reader from the ATLO-R series, enabling entry and exit control using a single controller.
Keypad
Built-in numeric keypad with high-durability mechanical buttons. The buttons are backlit with blue LEDs, which ensures excellent visibility in all lighting conditions.
Relay operating modes
NO/NC (Normally Open / Normally Closed) relay output. The lock release time is fully programmable, which allows for adjusting the device to electric strikes, electromagnetic locks, and gate drives.
Security and Features
The device has a function for signaling an open door (requires connecting a magnetic contact). Additionally, the lock offers the possibility of restoring default settings by the administrator and protection against unauthorized access to settings.
Signaling
The built-in buzzer emits audible signals confirming key presses and authorization. Visual signaling is performed using an LED that changes color depending on the status (e.g., green for access granted, red for error).
Power parameters
Powered by 12V DC voltage with a tolerance of ± 10%. Current consumption during idle operation is approx. 55 mA, which makes the device energy-efficient and easy to power from typical buffer power supplies for alarm systems.
Housing construction
Housing made of metal, which ensures resistance to vandalism. The IP40 ingress protection rating means protection against solid objects larger than 1 mm. The color scheme is an elegant combination of silver and black.
Environmental conditions
A wide operating temperature range from -45 °C to 60 °C allows for installation in unheated rooms or in places with large temperature fluctuations. The permissible humidity is 10% - 90% without condensation.
Software and Logic
The device has built-in firmware managing the access control logic. The system allows for quick adding of cards using the serial method, assigning PIN codes to specific cards, and deleting individual users based on their index number or possessed card. All programming operations are performed directly from the keypad using the administrator code, which eliminates the need for a computer. The processor logic ensures a fast response to card proximity (less than 0.1s) and stable handling of interrupts from exit buttons and door status sensors.
Mounting
Surface mounting using the included screw set. Compact dimensions of 77 x 110 x 27 mm allow for installation on narrow door frames or profiles.
Additional features
Dedicated doorbell button (potential-free contact) allowing for triggering a chime signal inside the building.
