● Connection with the Uninterruptible Power System (UPS)
This is an example of connection with the uninterruptible power system (UPS) to be installed to protect from a power outage.
When a signal is supplied to the outage detection I/O terminals from the uninterruptible power system (UPS), internal process-
ing (stops recording safely) will be started to shut off the power supply for this unit.
After completing the internal processing, a signal will be supplied from the outage processing end output terminal to the unin-
terruptible power system (UPS). Then, the power supply to this unit can be suspended.
● Connection of the control output
• When an alarm device such as a buzzer or a lamp is connected, the signal output from Pin Nos. 15 - 18 can be used to
notify the status by sounding a buzzer or lighting a lamp.
• The following example is of a connection with the HDD error output (pin no. 16).
