Security matrix for cascade security system

摘要

The security matrix (100) employs a number of security access modules and is divided into upper and lower parts (10,20), releasably coupled together via an electrical connection. T he bottom part has a number of reception shafts for the security access modules, the upper part incorporating a microprocessor and a memory, storing a switch logic for interconnection of the security access modules. The security access matrix may have a plug-in connector with a number of contact devices for connection with a computer. T he upper part of the security access module may have a reception shaft for a chip card (40).
