Figure: AN-303 Data Workflow
3.2 Use
Turn on: Press and hold the Turn on/off button at the back of the device for about
three seconds with the green light constant on until the buzzer gives out the sound.
Then the green light goes out. And the buzzer will stop automatically after three
beeps (di, di, di), indicating that the device is started.
Join network: When the device is turned on, the buzzer will sound "di" and "di",
indicating that the device is connected to the network.
Anti-dismantle button: After the device installation finished, the anti-dismantle
button is pushed against. When it detects the anti-dismantle button is released for
three seconds, the alarm will be reported and the red light will flash. When it
detects the tamper button is pushed against for three seconds, it will report
anti-dismantle status resume.
Turn off: Hold and press Turn on/off button for three seconds with the green
light on, until a long sound of buzzer sound heard and the green light is off.
Release the button, the device is off.
Note: It needs to wait for a while to reboot the device after it turned off.

4. Installation
Please prepare installation tools. Here are tools that may be used below.
Figure: Installation Tool
Quick Install
1. Put the back board at a proper position on the wall without tilting. Mark the
position and use percussion drill to make holes there.
2. Put the plastic cover in to the holes, align the back board in the holes on the wall,
use the taping screw to secure the back board.
3. Put AN-303 above the back board with AN-303 holder corresponding to back
board clasp. When they clasp together and pull AN-303 down.
Note: It can use gelatin sponge to adhere AN-303 on the surface where cannot drill
holes such as metal and glass wall. Put one side of gelatin sponge adhere to the
surface and put its other side to back board clasp. When AN-303 holder corresponding
to back board clasp get together and pull AN-303 down, a snap sound is heard. That
means installation is completed.

After the device locked successfully, you can edit parameters for setting up and query.
The parameters are for functions and LoRaWAN setting. For example, edit the high
temperature threshold value as 45℃, query the high temperature threshold value, it
will shows 45℃ in the Receive date box.
If you edit the high temperature threshold value as 60℃, query the high temperature threshold
value, it will shows 60℃ in the Receive date box.

Note:
After the device reboot, the device is in wireless configuration mode. Please click on Lock
address within 5 seconds. It will try to join the network in 5 sends later.
After the device locked successfully, and without operation in 15 seconds, the device
will exit from wireless configuration to network connection.
5.3 Remote configuration
Description: the remote configuration is done by AT command issued at the platform.
The port number is 220. The data format is hexadecimal with FF added in front. The
corresponding AT command needs to be converted into hexadecimal data first. The
hexadecimal data FF is added in front of the packet to send.
1. Convert the AT command into hexadecimal data step by step
a. AT command AT+REBOOT to convert 16-byte data for 41 54 2B 52 45 42 4F 4F
54 0D 0A
b. The last part of the command, 0D 0A, can be omitted
c. Add FF in front of it

2. Enter the device management platform, click Downlink, and fill in the data and
port number
3. After entering in the data and port number, click OK. Waiting for the node to
report, the platform will send the data to the corresponding node.
