The CEM Systems DCM 400 (Door Control Module) is an intelligent four-door controller designed to directly interface CEM Systems AC2000 access control system (version 10.2 and higher) with Wiegand or CEM Systems approved and supplied Open Supervised Device Protocol (OSDP v2) smart card readers.
The DCM 400 supports eight Wiegand or OSDP compliant readers (Entry/Exit configuration) for bi-directional control on four doors.
Using powerful 32-bit processors, the DCM 400 gives full off-line verification and decision making at the point of entry, even when host communication is not available.
