The AMC2 (Access Modular Controller) is used as an access controller in the access control systems: BISACE (Access Engine) from version 2.0 onward AMS (Access Management System) APE (Access Professional Edition). The device controls a group of one to eight access points. These access points, also known as entrances, can be: doors gates barriers turn stiles revolving doors mantraps ID card, PIN and biometric readers door opening elements sensors. The AMC2 can control a maximum of eight ID readers (depending on the reader type) and fully processes the access logic at the assigned entrances.The analog inputs have a status recognition of the connected lines.The relay outputs activate the door opening elements and/or generate the security activation and signaling.The AMC2 stores all necessary information in a battery-buffered memory and a compact flash storage element. Thus, even when the unit is offline, it checks independent authorization on access points, takes access decisions, controls closing/opening elements and registers movement events.The controller can be connected to the host system through one of the following interfaces, depending on the type of installation:With RS485 operation, a maximum of eight access controllers can be connected to one party line.The communication between the host system and the controller via RS485 is encrypted with up to AES256, depending on the firmware version used.In the communication chain of a system, the access controller is integrated between the host system and the peripheral devices.
