Mercury EP2500/LP2500 Intelligent Controllers


The EP2500 and LP2500 are powerful intelligent controllers with native network support and are scalable to 64 doors/ openings. Built on the Authentic Mercury access control platform, the controllers provide Ethernet-ready, fault-tolerant panel that can efficiently manage a large network of access panels in any system design.

The high-performance EP2500 and LP2500 use an Ethernet link to connect to a BluSKY™ based host and supports redundant downstream communications for access control and alarm management -- all in a single package

Capable of elaborate processes and procedures without host intervention, the intelligent controllers, once programmed, can function independently of the host.  They also support a range of embedded functionality and interfaces with an array of Mercury hardware devices, all while providing the decision-making oversight that each every system configuration requires.

For high device counts, large cardholder populations, and high volume system activity, the EP2500 and LP2500 are ideal controller platform.

Application Notes
