H. Circuit Boards
The FA5000 electronics contain all the necessary power supplies and circuitry to in-
put, record, monitor and playback data. In addition, circuitry to perform self–test
functions and provide signals to the appropriate status indicators is also integrated
into the FA5000 electronics. The removable circuit boards include the Aircraft Inter-
face PWA and Main Processor PWA.
I. Power, Control and Monitor Signal Interface Characteristics
Input power is 28 Vdc. At normal power level, an interruption equal to or less than
200 milliseconds will not affect the Model FA5000 CVR’s function. Upon application
or re-application, or normal, abnormal, or emergency power, the FA5000 will begin
storing data in memory within 250 milliseconds.
