2.6. Surveillance Function
Surveillance function continuously monitors such status at the major points from input to output of the system
as each unit operation, cable connections or communications between the units, and power supply.
If a unit fails or cable breaks, this is notified to the system operator by some means. Failure status of the
external equipment can also be accepted and notified.
When a failure has occurred, perform a set of operations: failure reception first to acknowledge failure state
and finally failure reset to restore the system to normal using the keys on the SX-2000SM or remote
microphone, or control input terminals of the system equipment.
Set the Surveillance intervals, intended surveillance points, and actions at the time of failure occurrence using
the SX-2000 Setting Software.
