Alarm input, output 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 is idle; the device
collects the logic “1”. When the input signal is grounded, the device collects the logic “0”.
