   • The system will automatically detect the GSM network.

3.2 Adding Wireless Sensors and Remote Controls

The system supports up to 99 wireless detectors. Follow these steps to add sensors and remote controls:

1. On the W202 panel, enter the programming mode (refer to the on-screen menu or specific key combination).
2. Select the option to "Add Sensor" or "Add Remote Control".
3. For Remote Controls (RC531/RC532):
   • Press any button on the remote control when prompted by the panel.
   • The panel will confirm successful programming.
4. For Door/Window Sensors (D025):
   • Separate the two parts of the door sensor when prompted by the panel.
   • The panel will confirm successful programming.
5. For Motion Sensors (P831/HW12/P861):
   • Trigger the motion sensor (e.g., by waving your hand in front of it) when prompted by the panel.
   • The panel will confirm successful programming.
6. Repeat for all desired sensors and remote controls.

3.3 Installing Sensors

• Door/Window Sensors: Install on the frame and moving part of doors or windows, ensuring the two parts are aligned and within 1cm of each other when closed.
• Motion Sensors: Mount in corners or on walls at an appropriate height (e.g., 2.2m for P831, 1-2m for vehicles or 2-4m for humans for P861 outdoor sensor) to cover the desired detection area. Avoid direct sunlight or heat sources.
• Siren: Place the wired siren near the main panel. Position wireless sirens (J008) in a prominent location, ideally outdoors, to maximize sound dispersion.
• Cameras: Install indoor cameras (K259) in central locations for wide coverage. Outdoor cameras (K268) should be mounted securely with a clear view of the area to be monitored.

4. Operating Instructions

4.1 Arming and Disarming the System

• Remote Control: Use the dedicated Arm, Disarm, Stay Arm, or Emergency keys on the RC531/RC532 remote.
• Tuya Smart App: Open the app on your smartphone and select the desired arming mode (Arm, Home Arm, Disarm).
• RFID Card: Swipe the RFID card over the designated area on the alarm panel to disarm the system.

4.2 Scheduled Arm/Disarm

You can set up to 8 groups of scheduled arm/disarm times to automate your security:

1. Navigate to the "Schedule" settings on the alarm panel.
2. Select an empty schedule group.

• Main Panel: The W202 panel has a built-in backup battery that provides approximately 8 hours of operation during a power outage. Ensure the panel is always connected to a reliable power source for continuous charging.
• Wireless Sensors:
  • P831 Motion Sensor: Requires 1x CR2450 battery (not included). The sensor will provide a low battery reminder.
  • D025 Door Sensor: Requires 1x 23A 12V battery (not included).
  • RC531/RC532 Remote Control: Requires 1x CR2032 battery (included).
  • S20 Smoke Detector: Requires 2x AAA batteries (not included).

5.2 Cleaning

• Wipe the alarm panel and sensors with a soft, dry cloth.
• Avoid using abrasive cleaners or solvents, as these can damage the device surfaces.

6. Troubleshooting

• System not connecting to Wi-Fi:
  • Ensure your Wi-Fi network is 2.4GHz. The system does not support 5GHz Wi-Fi.
  • Verify the Wi-Fi password entered in the Tuya Smart App is correct.
  • Check that the alarm panel is within range of your Wi-Fi router.
  • Restart your Wi-Fi router and the alarm panel.
• Sensors not triggering alarm:
  • Confirm that the sensors are properly paired with the alarm panel (refer to Section 3.2).
  • Check the batteries in the sensors and replace them if necessary.
  • Ensure motion sensors are not obstructed and are placed to cover the intended area.
  • For door/window sensors, verify the two parts are correctly aligned and within the specified gap when closed.
• No SMS/Call alerts:
  • Ensure a working 4G SIM card is inserted into the alarm panel and has sufficient credit/plan.
  • Verify that emergency contact numbers are correctly programmed in the system settings.
  • Check the signal strength of the GSM network on the alarm panel.
• False alarms:
  • Adjust the sensitivity settings of motion sensors if available.
  • Ensure motion sensors are not placed near heat sources, air vents, or in direct sunlight, which can cause false triggers.
  • Check door/window sensors for loose mounting or excessive gaps.

7. User Tips
