Alarm input, output connection description:

Step 1

Connect alarm input device to the alarm input of I/O port cable.

Step 2

Connect alarm output device to the ALARM_OUT and ALARM_OUT_GND of I/O port cable,

Alarm output is the relay switch output; alarm output port can only be connected to NO (normally

open) alarm device.

Step 3

Open the WEB, set alarm input and output correspondingly in alarm setup. Alarm input on the

WEB is corresponding to that of the device I/O port cable. When there is alarm, alarm input

device will generate signal of high and low level. Set corresponding NO and NC inputs.

Step 4

Set alarm output on the WEB, the alarm output is corresponding to the alarm output end of the

device, this is the alarm output port of the I/O port cable.

Please refer to the following figure for alarm input and output information. See Figure 1-4.

Alarm input: When the input signal is idle or grounded, the device can collect the different

statuses of the alarm input port. The input signal is connected to 3.3V or it is idle; the device

collects the logic “1”. When the input signal is grounded, the device collects the logic “0”.
