Edwards EST 3-CPU3 Central Processor Unit Module FIRE ALARM

The 3-CPU3 Central Processor Module is the control element for allrail modules and control/display modules installed in a control panel.The 3-CPU3 module performs the following functions: • Processes all information from modules installed within the cabinetas well as data received from other panels over the network datacircuit• Identifies and supervises all modules installed on the rail chassisand uses an integral watchdog to identify both hardware andsoftware faults• Supervises all traffic on the rail bus and implements ground faultdetection• Date-time stamps events and initiates timed events using aninternal clock with leap year function• Communicates with other 3-CPUx and 3-ANNCPUx modules overa Class A or Class B network data circuit (requires an optionalNetwork Communications card)• Distributes audio messages across a Class A or Class B networkaudio circuit (requires an optional Network Communications card)In addition, the 3-CPU3 module:• Provides connections for two optically iso
