Product DescriptionThe ATRIUM master card provides a secure master credential for access control systems by allowing administrators to activate enrollment mode at any compatible card reader and manage user credentials, door permissions and system settings across multiple doors and access levels. It enables easy programming and management of access cards through the main controller’s built-in web interface or free management software, supports large scale installations with up to 500 doors and 10,000 users and integrates smoothly with proximity card readers, keypads or wireless door handles to form a complete scalable security solution. The durable plastic card ensures reliable reader recognition and reduces the risk of unauthorized entry when handled properly and the straightforward functionality simplifies commissioning and maintenance for system installers.
