Power supply is provided thru "respective" computer : ACCLRM #1 from ELAC 1,ACCLRM #2 from SEC 1, ACCLRM #3 from ELAC 2, ACCLRM #4 from SEC 2. Single accelerometer fault causes only class 2 maintenace message, F/CTL will be displayed as STATUS for pilots. Btw. if ELAC 1, SEC 1 or 2 is deactivated as per MEL, due to power supply you lose one accelerometer too. If more than one acclrm. fails, aircraft switch to ALTERNATE or DIRECT law. FCOM probably does not cover description so deep. Just schematic in DSC 27-10-20 shows accelerometers input to ELACs. I am sorry, whole logic is not really so simple as I was able describe here from my memory.
