The CEM Systems DCM200 (Door Control Module) is an intelligent two-door controller designed to be highly secure and directly interface with CEM Systems AC2000 access control software (version 10.2 and higher). It also supports up to four Wiegand or CEM Systems approved Open Supervised Device Protocol (OSDP v2) smart card readers. These OSDPv2 compliant readers can be used (Entry/Exit configuration) for bi-directional control on two doors.
Using powerful 32-bit processors, the DCM200 gives full on-line or offline verification and decision making at the point of entry, even when host communication is not available
