Connection with the Uninterrupted Power Supply (UPS)

• The figure shows an example of how to connect a UPS as protection against power failures.
• 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

Connection with CONTROL output

• Signal outputs (Pins #1-6, 18) can be used to connect alarm devices such as a buzzer or lamp to inform you of the opera-

tion status by sounding a buzzer or lighting a lamp when a signal is output.

• The figure below shows an example of how to connect an alarm output (Pin #6) to warn of low remaining HDD capacity.
