64 door controller. Enhanced capabilities to retain large database configurations from any RedCloud appliance. The policies and schedules for all identities, and for all hardware configurations, from the database in a RedCloud appliance are distributed into the controller so security is enforced at the door, even if the upstream network communications are interrupted. Supports all standard (Wiegand interface) reader technologies. Requires MR51e (single door, PoE interface) or MR-50 (single door, RS-485 interface) or MR-52 (dual door, RS-485 interface) door/reader interface modules at each door that runs from the EP2500 controller.
