The Access Modular Controller (AMC) is supported by the Access Professional Edition (APE), BIS Access Engine (ACE) and the Access Management System (AMS). The device is able to control up to two Wiegand card readers. It is designed to fully process the access logic at assigned access points. Access points consist of doors, gates, barriers, turn stiles, revolving doors, mantraps, ID card readers, door opening elements and sensors. The controller stores all necessary information in a battery-buffered memory and in a compact flash storage element.
