Controller Platform
The Mercury Access Platform EP2500 is an intelligent controller platform with native network support. This powerful and high-performance platform provides an Ethernet ready, fault-tolerant panel capable of efficiently managing a large network of access panels in any system design.
Based on the intelligent next-generation Mercury Access Foundation, the platform uses an RS-485 or Ethernet link to connect to a Windows or Linux host to provide access control, alarm management and scheduled operations all in one package. The EP2500 is capable of elaborate processes and procedures without host intervention. Once configured, the EP2500 functions independently of the host, and is capable of controlling access, managing alarms, interfacing with an array of Mercury hardware devices, all while providing the decision-making oversight that each system configuration requires.
