The ADE5300 provides a local interface between the central controller (AC5100, AC5102 or AC5200) and up to 8 card readers. From the ADE5300‚ the information held within the access cards is transmitted to the central controller. Each time an access attempt is made the central controller verifies the data on the ID card and will then ei-ther allow or deny access. The ADE5300 can be configured to control up to 8 doors separately or up to 4 doors that include both entry and exit readers. All variations are possible; for example, you can have six single-reader doors and 1 dual-reader door connected
