● 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 input terminals from the uninterruptible power system (UPS), internal pro-

cessing (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).
