Extra Info
Scalable Design
The DS-K2704X is engineered for growth. Out of the box, it supports 4-door control, but with the addition of up to 62 DS-K2M002X access modules, it can be expanded to manage as many as 128 doors. This makes it ideal for both medium-scale facilities and large enterprise deployments such as airports, campuses, and corporate offices.
Advanced Access Functions
Built with enterprise security in mind, the controller offers powerful features including multi-factor authentication (card, PIN, or biometric integration), anti-passback (to prevent credential sharing), and interlocking (managing access between secured zones). These functions ensure compliance with strict security policies and add extra layers of protection for sensitive areas.
Web-Based Management
Unlike traditional controllers that require PC software, this unit features a built-in web server interface. Administrators and installers can configure, monitor, and update the system directly through any standard browser. This saves setup time, reduces IT overhead, and simplifies remote maintenance, making it more efficient to deploy in large projects.
Status Indicators
Equipped with 12 front-panel status indicators, the controller provides real-time feedback on system health, door states, alarms, and network connections. This visual guidance allows technicians to troubleshoot quickly, reducing downtime during installation and maintenance.
