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
269M - 1999.
