Uninterruptible Power Supply (UPS) Connectivity
This section explains how to connect an Uninterruptible Power Supply (hereafter UPS) as part of your power outage countermeasures.
When the recorder receives a power outage detection signal from the UPS, it begins its internal power off sequence (process to stop recording to protect the recorder).
After the internal power off sequence is complete, a signal is output from the Power outage recovery completion output to the UPS and the recorder is then ready to turn off power.
