The alarm setup interface is shown as below.
Step 1. Connect the alarm input device to the IN alarm input port on the rear panel I/O port.
Step 2. Connect the alarm output device to the NO alarm output port and C alarm output public
port on the rear panel I/O port. The alarm output port supports NO (normal open) alarm
device only.
Step 3. Open the Web, go to the Figure 2-5. Here you can set the alarm input setup and alarm
output setup. Here the alarm input is the alarm input on the rear panel I/O port (as IN
port). Then you can select the corresponding type (NO/NC) according to the high/low
level type when an alarm occurs.
Step 4. Set the WEB alarm output. The alarm output 01 is the alarm output port of the device
rear panel I/O port (as the NO port).

Please refer to the following figure for alarm input information. See Figure 2-6.
Alarm input: When the input signal is idle or grounded, the device can collect the different
statuses of the alarm input port. When the input signal is connected to the 3.3V or is idle, the
device collects the logic “1”. When the input signal is grounded, the device collects the logic “0”.
