Dahua Airshield ARD912-W2(D) — Wireless Flood Detector

Water leaks can cause serious property damage, making early warning crucial. The Dahua Airshield ARD912-W2(D) wireless flood detector reliably detects water flooding and effectively minimizes the risk of signal loss thanks to two-way communication with frequency hopping. With an operating frequency of 868 MHz and a range of up to 1,200 meters in open space, it is suitable even for larger areas. It offers long-term, maintenance-free protection thanks to a CR123A battery that lasts up to 3 years under normal operating conditions.

Reliable Detection and Secure Communication

The detector is designed for maximum reliability through the integration of AES128 encryption, ensuring the security of transmitted data. The frequency hopping feature guarantees a stable connection even in environments with signal interference. Detector sensitivity can be adjusted to specific conditions, enhancing detection accuracy and reducing the risk of false alarms.

Temperature Monitoring and Overheat Protection

In addition to water detection, the device monitors ambient temperature and triggers an alarm in the event of overheating, adding an extra layer of protection. This feature is ideal for spaces where monitoring both water leaks and temperature conditions is important. ### Easy Maintenance and Remote Updates Support for remote cloud updates ensures the device always runs the latest software. Automatic recovery in the event of an update failure eliminates the risk of the device becoming inoperable during the process. The PC + ABS plastic housing ensures durability and a long service life, even in demanding conditions.
