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 housing is exceptionally durable and strong, protecting against the elements and potential damage.
The siren is equipped with a powerful sound pressure of ≥ 105 ± 3 dB at a distance of 1 meter and guarantees a clear and audible sound alarm in the event of a burglary or incident. It also has a signal strength detection function, which helps it maintain stable communication with the security system.
The device runs on two CR123A batteries, which provide 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 approximately 2.5 years in normal operating condition, with a 120 second alarm twice a week.
In addition, the siren includes a frequency hopping function and two-way communication technology, ensuring a stable and secure connection with the security system. It supports cloud updates, so you can take advantage of 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 fluctuations) and being suitable for use in different environments.
