3. Setup

3.1 Physical Installation

The DuoSmart B20 siren is designed for wall mounting. Choose a suitable location, preferably outdoors or in a prominent area, where the siren's sound and strobe light can be effective. Use the included screws and anchors to securely mount the device.

3.2 Power Connection

Connect the included 9V 600mA power adapter to the siren's voltage input port. Plug the adapter into a standard electrical outlet. The siren operates primarily via this power adapter. It may contain an internal backup battery for temporary operation during power outages, but it is not designed for continuous wireless operation.

4. Operating Instructions

4.1 Arming and Disarming

You can arm, disarm, or trigger an SOS alarm remotely using the mobile app or the included remote control.

• Arm (Total): Activates all connected sensors. The siren will trigger if any sensor detects activity.
• Arm (Partial/Stay): Activates perimeter sensors while allowing movement within the interior without triggering the alarm. Interior sensors will not activate the siren in this mode.
• Disarm: Deactivates the alarm system.
• SOS: Triggers the siren immediately for emergency situations.

4.2 Adding RF 433.92 MHz Devices

The siren supports up to 60 additional RF 433.92 MHz devices, such as PIR motion sensors and magnetic contact sensors. Refer to the DuoSmart app for specific instructions on how to pair these devices. Once paired, these devices will trigger the siren based on their configuration and the siren's arming mode.

• 24-Hour Audible: Certain devices can be configured to activate the siren at all times, even when the siren is in disarmed mode. This is typically used for smoke detectors or gas leak sensors.

4.3 Scene Execution

Leverage the DuoSmart/Smartlife/Tuya app to create smart scenes. For example, you can configure the siren to trigger other smart devices (e.g., turning on lights) when an alarm is activated, enhancing your overall security solution.

5. Maintenance

5.1 Cleaning

Wipe the siren's exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents, as these can damage the device. Ensure no moisture enters the device.

5.2 Tamper Switch

The siren is equipped with a tamper switch (visible on the rear, refer to Section 3.2 image). If the siren is forcibly removed from its mounting location while armed, this switch will trigger an alarm, providing an additional layer of security.

5.3 Power Supply

Ensure the power adapter remains securely connected to a functional power outlet. Regularly check the power cable for any signs of damage. If the siren contains an internal backup battery, ensure it is charged by keeping the device connected to power. Consult the app for battery status if available.

6. Troubleshooting

• Siren not connecting to WiFi:
  Ensure your WiFi network is 2.4GHz. Check your WiFi password. Move the siren closer to your router. Restart your router and the siren.
• Siren not responding to app/remote:
  Verify the siren is powered on. Check if the siren is connected to WiFi (indicator light status). Ensure the remote control battery is not depleted. Re-pair the remote control if necessary.
• RF sensors not triggering siren:
  Ensure the sensors are properly paired with the siren. Check the sensor batteries. Verify the siren is in an armed mode (Total or Partial, depending on sensor type). Check the sensor's operating mode (e.g., 24-hour audible).
• Siren sounds unexpectedly:
  Check the app for recent activity logs to identify which sensor or event triggered the alarm. Inspect sensors for false triggers (e.g., motion sensor detecting pets, magnetic sensor misaligned).
• Low siren volume:
  Ensure the siren's speaker is not obstructed. Check app settings for volume control if available.
