Step 2
Connect the alarm output device to the alarm output end of the I/O port. The alarm output
is a relay switch output, which can only connect to OUT_GND alarm devices.
ALARM_OUT(ALARM_COM) and ALARM_OUT_GND(ALARM_NO) constitute a switch that
provides the alarm output.
The switch is open normally and closed when there is an alarm output.
ALARM_COM might represent ALARM_C or C; ALARM_NO might represent N. The
following figure is for reference only, please refer to the actual device for more
information.

Step 3
Log in to the webpage, and then configure the alarm input and alarm output in alarm
settings.
●
The alarm input on the webpage corresponds with the alarm input end of the I/O port.
There will be high level and low level alarm signals generated by the alarm input device
when an alarm occurs. Set the input mode to "NO" (default) if the alarm input signal is
logic "0" and to "NC" if the alarm input signal is logic "1".
●
The alarm output on the webpage corresponds with the alarm output end of the
device, which is also the alarm output end of the I/O port.
