1.8 Expander Supervision
A watchdog supervises the operation of the
FPP-RNAC-8A-4C processor and attempts to restart
it if it fails. If the processor does not restart, or the
power fails entirely, the installer-supplied EOL device
disconnects from the input to report the trouble
condition. If power is available, the System Trouble
LED lights if the system encounters an error.
1.9 Auxiliary Power Supply
The FPP-RNAC-8A-4C can be wired to supply
unsupervised constant auxiliary power through its
NAC outputs. Refer to Section
3.7.2 Auxiliary Circuits
on page
16 for additional information.
2.0 Installing the FPP-RNAC-8A-4C
The FPP-RNAC-8A-4C board and the enclosure are shipped together. The board, however, needs to be
mounted into the enclosure. Hardware for mounting the board in the enclosure is supplied in the hardware
pack.
