DS-K2220X(P) - Pro Elevator Controller

The DS-K2220X(P) is an enterprise-grade elevator access control mainboard manufactured by Hikvision to manage and restrict vertical floor access within high-rise buildings. Dropping the bulky metal cabinet and built-in power supply found in the base kit, this standalone "(P)" board variant is designed for installation into custom enclosures or shared system racks, while maintaining a local storage capacity for 50,000 users, 100,000 cards, 30,000 fingerprints, and 300,000 offline event logs. The board manages floor permissions for up to 128 structural stories, utilizing dual uplink channels via wired TCP/IP and RS-485 to connect with master systems while supporting downstream connections for two separate Wiegand or RS-485 card readers. For compliance with structural safety rules, the circuit board incorporates physical input interfaces to link directly with one emergency override button, one fire alarm release button, one manual maintenance switch, and two chassis tamper-detection sensors.
