CPU800 Expert Central Processor

The CPU-800 provides the main processing power behind the MX detection panels. It is a multi-layer PCB and contains the CPU, the memory and interface electronics. The CPU-800 plugs into the Field Interface Module (FIM800) which forms the motherboard in most MX detection panels.

The CPU-800 contains a Data Memory (SRAM), a Program Memory (Flash EPROM), a Configuration Memory (Flash EPROM) and a Boot ROM (EPROM).

The use of flash EPROM allows program upgrades to be downloaded locally or remotely without the need for changing chips.

The CPU-800 provides power for the following functions:

• Full alarm and fault monitoring for up to 1000 addressable points including central loop processing of MX Fastlogic expert algorithms
• Concurrent operation of the main user interface and 2 remote user interfaces including one remote dial up or networked user interface
• Peer to peer interaction with up to 99 other MX detection panels
• Cause and core effect using up to 1000 input, output groups, delay timers and logic functions

The Board provides 4 serial channels to the FIM800 - 2 for RS232 (PCs, modems, printer and/or data loggers), 1 for the remote bus (RBUS) to the main user interface and repeaters and 1 for Network Port (FSI, ThornNet/MX Net or MX-FILNET).
