Product Description
The DS-K2M002X extends a Hikvision access controller to manage two additional doors over an RS-485 link. For installers working on multi-door commercial or industrial sites, this is the standard route to scale a controller without swapping the head-end unit.
Reader connectivity
Card readers connect via either RS-485 (using the OSDP protocol) or Wiegand. That dual-interface support means the module can accept card readers, keypads or biometric readers, whichever the project spec calls for, without locking the installation to one reader family.
Panel installation
- DIN rail mounting for standard control cabinet fit
- LED indicators covering power, communication, running and door status — useful for fault-finding during commissioning and ongoing maintenance
- RS-485 connection back to the main access controller for data transmission across the network
Power resilience
The module manages battery charging and discharging, so where a backup battery is fitted, it can help keep the connected doors operating through a mains interruption.
Where it fits
This is an expansion module, not a standalone controller — it's built to work alongside a compatible Hikvision access control panel as part of a wider system, adding two-door capacity per unit to that installation.
