4.2 Power Connection
- Connect the provided 5V power adapter to the DC5V input port on the siren.
- Plug the power adapter into a standard 100-240V AC power outlet.
- Ensure the siren is powered on using the 'ON/OFF' switch. The built-in battery will begin charging automatically.
4.3 Mounting
The siren can be mounted on a floor or wall. Use the provided screws to secure the device in your desired location. Ensure the mounting location allows for optimal sound and light dispersion and is within range of other wireless alarm components.
4.4 Pairing with Alarm System (Optional)
The siren can function as a standalone unit or integrate with a compatible alarm host, such as the PG103 WIFI alarm host. It can also act as an alarm host itself, capable of learning up to 5 remote controls and 20 detectors (e.g., infrared sensors, door/window magnetic sensors).

Figure 3: The siren can integrate with a PG103 WIFI alarm host for expanded coverage.

Figure 4: The siren can learn and manage up to 5 remote controls and 20 detectors.
Refer to the specific instructions for your remote controls or detectors for their pairing procedures. Generally, this involves putting the siren into a 'learning' mode (often via the 'SET' button or APP) and then triggering the remote/detector.
5. Operating Instructions
5.1 Basic Operation
Once powered on and optionally paired, the siren will respond to signals from connected remote controls or alarm detectors. When an alarm is triggered, the siren will activate its 8 LED lights and emit an 80dB sound.

Figure 5: The siren activates with sound and light upon detecting an intrusion.
5.2 Smart APP Control (If Applicable)
The siren supports smart one-key functions via a compatible mobile application. This allows for remote control of arming and disarming:
- Outdoor Arm: Activates the alarm system for full protection.
- Indoor Arm: Activates perimeter protection while allowing movement inside.
- Emergency Arm: Triggers an immediate alarm.
- Disarm: Deactivates the alarm system.
When the alarm host receives a signal, it will send a message to the owner (if configured) and activate the sound and light alarm on the siren.

6. Maintenance
To ensure optimal performance and longevity of your Sonew Wireless Sound and Light Strobe Siren, follow these maintenance guidelines:
- Cleaning: Wipe the device regularly with a soft, dry cloth. Avoid using abrasive cleaners or solvents that could damage the surface.
- Battery Care: The built-in lithium battery is designed for backup power. For best battery life, keep the device connected to power when possible. If storing the device for an extended period, ensure the battery is partially charged (around 50%) and recharge it every few months.
- Placement: Ensure the siren is placed in a location free from excessive moisture, extreme temperatures, or direct sunlight, which can affect its electronic components.
7. Troubleshooting
If you encounter issues with your Sonew Wireless Sound and Light Strobe Siren, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Siren does not activate. | No power, low battery, or not properly paired. | Check power connection. Ensure the 'ON/OFF' switch is in the 'ON' position. Verify battery charge. Re-pair with remote controls or detectors if necessary. |
| Siren does not respond to APP commands. | App not configured, siren not connected to network, or app compatibility issues. | Ensure the siren is properly connected to your WiFi network (if applicable). Verify the app is correctly installed and configured. If issues persist, consider using physical remote controls as an alternative. |
| Siren activates unexpectedly. | False alarm from detector, or interference. | Check connected detectors for false triggers. Ensure no strong electromagnetic interference sources are nearby. |
| Battery backup not working. | Battery depleted or faulty. | Ensure the device has been connected to power for sufficient charging time. If the issue persists, the battery may need replacement. |
