Details
The fault report contacts are closed when the card detects an internal failure or a power loss condition.
The fault report contacts are closed for about 2 milliseconds every 16 ms to report any error for which
SMPTE fault reporting has been enabled.
Some internal failures may include:
 
Hardware failure of any card or power supply.
 
Loss of AC power to any power supply
 
Soft” errors from any card setup to detect and report such errors
For additional information on alarm system design, refer to the SMPTE document ANSI/SMPTE
