OSSI Overland Safety Systems

The MAC-4R is part of OSSI’s complete PSIM solution. The MAC-4R is an intelligent distributed processing access control panel. The panel supports ladder logic programming providing ultimate flexibility. The I/O style board provides traditional flat mounting in an enclosure or rack termination which allows for 28 doors of access control in a small 18” x 18” enclosure footprint. The integrated Lonworks communications protocol and flexible communications topology supports up to 126 controllers on one communications line. Each controller can be connected to one or multiple host devices for redundancy. Connection options include serial, fiber or Ethernet adapters. Ethernet interfaces provide a direct connection to local or wide-area networks reducing infrastructure and lowering installation costs.
