The Card Reader Controller (CRC) provides the power and electronics required to monitor and control a single door with both entry and exit readers. The unit is designed to mount in close proximity to the door it controls, however it can be located remotely from the readers in retrofit applications.

All access decisions are made locally in the CRC. The CRC’s nonvolatile memory can hold schedules and holiday information for up to 8,000 cardholders. The CRCXM has additional memory, and supports up to 36,000 cardholders. The memory also retains the last 5,000/20,000 events for logging purposes. This history information is uploaded at the request of the access control database for use in a variety of reports.

The unit provides 12 Vdc @ ½ amp for door strike or magnetic lock requirements. An integral standby battery can provide up to four hours of service for applications that use electric door strikes. An integral tamper switch is also provided.
