Scale your access control infrastructure effortlessly with the Hikvision DS-K2M002X Ultra Series Access Module, the essential expansion component for DS-K270X series master controllers. Each module delivers reliable control for 2 doors, featuring dedicated interfaces for locks, exit buttons, door contacts, alarms, and tamper protection—enabling seamless addition of doors without compromising performance.

Connect up to 4 RS-485 card readers (using OSDP protocol for secure, encrypted communication) and 2 Wiegand readers (26/34 bit standard, with custom format support), accommodating diverse authentication methods like cards, fingerprints, PINs, or QR codes from Hikvision or third-party devices. The module links to the master controller via RS-485 (with redundancy support for fault-tolerant wiring over long distances), allowing massive scalability—cascade multiple DS-K2M002X units to extend door capacity dramatically in large facilities.

Key professional features include alarm input/output linkage, tamper detection, fire interface compatibility (via master), battery charge/discharge for backup power during outages, and 6 LED indicators (power, running status, communication, and door status) for quick diagnostics. Powered by 12 VDC with low consumption, it operates reliably from -10°C to 55°C and installs easily on DIN rails or guide rails for clean, rack-mounted setups.

Ideal for high-traffic, mission-critical environments such as airports, subways, banks, industrial plants, hospitals, universities, and corporate campuses requiring expandable, redundant, and secure door management. Fully integrated with HikCentral Professional, Hik-Connect, and master controller web configuration—no extra software needed. Build a future-proof, distributed access system with this robust Ultra Series module.
