DHI-ARA12-W2(868) Wireless Indoor Siren

The DAHUA DHI-ARA12-W2(868) WIRELESS SIREN combines state-of-the-art technology with a robust design to provide optimal protection against intruders and other incidents.

It is specifically designed for wireless use, making it easy to install and integrate into your existing security system. You can place it anywhere in your home without worrying about bulky cables. The PC + ABS casing is exceptionally durable and strong, protecting it from the elements and potential damage.

The siren is equipped with a powerful sound pressure of ≥ 105 ± 3 dB at a distance of 1 metre and guarantees a clear and audible sound alarm in case of a burglary or incident. It also has a signal strength detection function, allowing it to maintain stable communication with the security system.

The device runs on two CR123A batteries, providing a reliable power source. With a maximum power consumption of only 240 mW, it is energy-efficient and the battery lasts longer. The siren can operate for about 2.5 years in normal operating condition, with 120-second alarms twice a week.

In addition, the siren includes a frequency hopping function and two-way communication technology, ensuring a stable and secure connection to the security system. It supports cloud updates, so you can benefit from the latest improvements and features without any extra effort.

It also has the advantage of being able to withstand different conditions (different climates, humidity, temperature variations) and is suitable for use in different environments.
