KK 503 Wall Mount Access Control Readers

Designed and crafted to ensure top-notch security, the Access Control Reader KK 503 identifies the card assigned to each user.

Its ground-breaking design ensures an easy fit in any work environment, including elegant and stylish settings. Its modular architecture expresses technology and consistency, and its wall mount design is aimed at meeting all installation requirements.

Thanks to its state-of-the-art technology for multi-door control, a single Karpos Controller MXP 450 can handle up to 16 readers, with a maximum cabling length of 200 meters on two separate protected channels.

An intuitive and immediate user interface, providing acoustic and visual signals about authorized or denied access; a back-lighted keypad and capacitive fingerprint sensor interacting with the user and including PIN code or fingerprint entry features: all of this, and more, distinguish the wide versioning of the KK 503 line.
