•When a power failure detect input is received from the UPS, the disk recorder's power failure process starts to process this signal to turn off its power supply.

•When the power failure process is completed, the disk recorder outputs a signal to the UPS.

•When the UPS receives the completion signal from the disk recorder, the disk recorder's power is turned off
