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).
Connection with the Uninterruptible Power System (UPS)
This is an example of a 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 process-
ing (stops recording safely) will start to shut off the power supply for the recorder.
After completing the internal processing, a signal will be supplied from the outage processing end output terminal to the uninter-
ruptible power system (UPS). Then, the power supply to the recorder can be suspended.
Important:
• BesuretouseanUPSthatprovidesasinewaveoutput.
Do not use an UPS that provides a square wave. It may damage the recorder.
