Product information

Description

DAHUA ARD912-W2(868) is a wireless, battery-powered water detector designed to sense the presence of water and notify connected systems. The compact white housing measures 84.7×84.7×32.5 mm and operates in temperatures from -10 °C to 55 °C. The device uses an 868 MHz-compatible wireless link with frequency hopping and two-way communication to maintain a stable connection and supports encrypted communication and jamming detection for reliable alert delivery. Built-in temperature measurement and sensitivity adjustment allow adaptation to different environments and leak-detection needs.

Advantages

The detector offers stable wireless communication through frequency hopping and two-way transmission, reducing the chance of missed alerts. Communication encryption and jamming detection improve security and resilience against interference. Battery-powered operation and a compact form factor simplify installation in basements, boiler rooms, kitchens and near appliances without the need for external power. On-board temperature sensing and sensitivity adjustment allow more precise detection and the option to trigger an overheating alarm if required.

Suitable for

  • Early leak detection near water heaters, boilers and pipes
  • Monitoring around washing machines, dishwashers and refrigerators
  • Protection of basements, utility rooms and crawl spaces from water ingress
  • Integration with building alarm systems for automated alerts

Key specifications

  • Power: battery-powered (removable/replaceable batteries)
  • Wireless frequency: 868 MHz-compatible link with frequency hopping
  • Communication: two-way communication with encryption and jamming detection
  • Operating temperature range: -10 °C to 55 °C
  • Dimensions: 84.7 × 84.7 × 32.5 mm
  • Functions: water presence detection, environmental temperature measurement, overheating alarm support, sensitivity adjustment
  • Firmware: supports cloud update with automatic restore on update failure

How to use

Place the DAHUA ARD912-W2(868) on a flat, stable surface or mount it in the area where water leaks are most likely to occur, such as near drains, water heaters, washing machines or under sinks. Install batteries according to the manufacturer's instructions, then register the detector with the compatible 868 MHz hub or control panel following the system pairing procedure. Adjust sensitivity settings as needed to avoid false alarms from condensation or splashes, and enable temperature monitoring or overheating alarm if required. Test the detector after installation using the recommended test procedure to verify communication and alarm reporting.

Usage recommendations

For reliable operation, install the detector at low points where water would collect, keep it free of dust and debris, replace batteries according to the device's battery-life indicators, and perform periodic tests. Avoid placing the detector where routine splashes or high humidity might cause repeated false alarms; instead, use sensitivity adjustment to fine-tune detection. When integrating into an alarm or building management system, ensure the 868 MHz link and encryption settings match the receiving hub's requirements.
