3.3.1 Remote Control Pairing
To pair a remote control, navigate to the 'Menu' on the alarm host, then 'Parts', and select 'Remote'. Click 'Add' and then press any button on the remote control to complete the pairing. Once paired, the remote can arm and disarm the system.
3.3.2 RFID Tag Pairing
From the 'Menu', go to 'Parts', then 'RFID'. Click 'Add' and place the RFID tag on the corresponding position of the host for sensing. The system will confirm successful learning. RFID tags can then be used to arm or disarm the system.
3.3.3 Magnetic Door/Window Sensor Pairing
Access 'Menu', then 'Parts', and select 'Detector'. Click 'Add'. Choose 'Door Alarm' in the first line and 'Out Arm Active' in the second line. Confirm, then separate the two parts of the door sensor to pair successfully. When armed, separating the sensor parts will trigger the alarm.
3.3.4 Infrared Detector Pairing (Motion Sensor)
First, turn on the switch of the infrared detector and allow it to enter self-test mode. On the alarm host, go to 'Menu', 'Parts', then 'Detector'. Click 'Add'. Select 'Panic Alarm' in the first line and '24 Hours Active' in the second line. Confirm, then wave your hand in front of the infrared detector to complete pairing. When armed, the infrared detector will trigger the alarm upon sensing human body movement.
3.3.5 SOS Button Pairing
From the 'Menu', go to 'Parts', then 'Detector'. Click 'Add'. Select 'Panic Alarm' in the first line and '24 Hours Active' in the second line. Confirm, then press the SOS button. Once paired, pressing the SOS button when the host is armed will trigger the alarm.
3.3.6 Doorbell Pairing
Navigate to 'Menu', 'Parts', then 'Detector'. Click 'Add'. Select 'Door Alarm' in the first line and 'Doorbell' in the second line. Confirm, then press the doorbell button. The host will receive a reminder when the doorbell is pressed.
3.3.7 Wireless Sound and Light Siren Pairing
Turn on the siren switch. Long press the button on the siren until you hear three beeps. On the alarm host, go to 'Menu', 'Parts', then 'Siren Learn'. Confirm. When the main unit alarms, the paired siren will also sound.
3.3.8 Smoke Detector Pairing
From the 'Menu', go to 'Parts', then 'Detector'. Click 'Add'. Select 'Gas Alarm' in the first line and '24 Hours Active' in the second line. Confirm. Press and hold the smoke detector button. Once paired, the smoke detector will trigger the alarm on the host when smoke is detected.

5. Maintenance
5.1 Battery Backup
The main alarm host includes a backup battery to ensure continuous operation during power outages. The system will send an SMS notification if the power goes off and when it comes back on.
5.2 Sensor Battery Replacement
Individual sensors (motion detectors, door/window sensors, SOS button) are battery-powered. When a sensor's battery is low, the system will typically provide an alert. Refer to the specific sensor's mini-manual or the main alarm host's interface for instructions on replacing batteries. Always use the recommended battery type.
6. Troubleshooting
- System not connecting to WiFi: Ensure your WiFi network is 2.4GHz. The system does not support 5GHz networks. Verify your WiFi password is correct.
- Sensors not triggering alarm: Check if the sensor is properly paired with the main host (refer to Section 3.3). Ensure the sensor's battery is not low. Verify the sensor is installed correctly within its effective range.
- No app notifications: Check your smartphone's notification settings for the Smart Life/Tuya App to ensure notifications are enabled. Verify the app is connected to the alarm host and your phone has internet access.
- GSM/4G functions not working: Ensure a valid and active SIM card is inserted correctly. Check the SIM card's balance and network coverage in your area.
