Setup and Installation
Before Installation
- Ensure your Nivian alarm system is properly set up and ready for device pairing.
- Choose a clean, dry surface on your door or window frame for mounting.
- The sensor is designed for indoor use only.
Mounting the Sensor
The Nivian NV-D3D-U1 sensor is designed for easy, cable-free installation. It includes three installation supports to accommodate different heights and mounting scenarios.
- Identify the main sensor unit and the magnetic contact unit.
- Position the main sensor unit on the fixed frame of the door or window.
- Position the magnetic contact unit on the moving part of the door or window, aligning it with the main sensor unit. The two units should be no more than 1 cm apart when the door/window is closed.
- Use the provided adhesive pads or screws for secure mounting. Ensure the units are firmly attached.

Pairing with Nivian Alarm System
The detector communicates with your Nivian alarm system via 433 MHz wireless frequency. Refer to your Nivian alarm system's manual for specific instructions on how to add new wireless sensors. Generally, this involves putting the alarm hub into pairing mode and then triggering the door/window sensor (e.g., by separating the two parts) to register it with the system.

Operating Instructions
Functionality
Once installed and paired, the Nivian NV-D3D-U1 detector monitors the state of your door or window. When the magnetic contact unit separates from the main sensor unit (i.e., the door or window opens), the sensor transmits a signal to your Nivian alarm system.
Alarm System Response
The alarm system will respond according to its programmed settings. This may include sounding an alarm, sending notifications to your smartphone via the TUYA Smart app, or activating other connected security devices.
Anti-Tamper Feature
The sensor is equipped with an anti-tamper mechanism. If the main unit is forcibly removed from its mounting surface, it will trigger an alert to your alarm system, providing an additional layer of security.
Maintenance
Battery Replacement
The Nivian NV-D3D-U1 is battery-powered. While designed for long battery life, periodic replacement will be necessary. The specific battery type is Lithium-ion. When the battery level is low, your alarm system or the TUYA Smart app may provide a notification. To replace the battery, carefully open the main sensor unit, remove the old battery, and insert a new one, ensuring correct polarity. Batteries are not included with the product.
Cleaning
Clean the sensor units periodically with a soft, dry cloth. Avoid using abrasive cleaners or solvents, as these can damage the device.
Environmental Conditions
Ensure the sensor remains in an indoor environment, away from extreme temperatures, high humidity, and direct water exposure.
Troubleshooting
Sensor Not Responding
- Check Battery: Ensure the battery is correctly installed and has sufficient charge. Replace if necessary.
- Check Alignment: Verify that the main sensor unit and the magnetic contact unit are properly aligned and within 1 cm of each other when the door/window is closed.
- Re-pair Sensor: If the sensor loses connection, try re-pairing it with your Nivian alarm system according to the alarm system's manual.
- Obstructions: Ensure there are no metallic objects or other obstructions interfering with the wireless signal between the sensor and the alarm hub.
False Alarms
- Secure Mounting: Ensure both sensor units are securely mounted and do not shift with vibrations or movement.
- Gap Adjustment: Confirm the gap between the two units is appropriate when the door/window is closed.
App Connection Issues
- Alarm Hub Connection: Ensure your Nivian alarm hub is connected to the internet and functioning correctly.
- TUYA Smart App: Verify that the TUYA Smart app is updated to the latest version and your smartphone has a stable internet connection.
