Sonix 350-d Technical Manual
3.4.6 Fault outputs
Both PSU Fault and Amp Fault outputs are a volt-free
contact output. The contact is closed when the unit is
healthy and open when there is a fault or power to the
unit is lost.
Some of the faults monitored can be disabled in
configuration, see the SAS Product Manual for details.
Both fault outputs will hold their output for
approximately 10 seconds before clearing after any fault
has cleared, this is to allow any transient faults to be
registered by any external monitoring.

There is no configuration option to change the sense for either
output.
