The devolo alarm siren gives your smart home an unmistakable voice. With 110 decibels, it loudly warns of any dangers threatening your loved ones or your belongings. Whether it's the door or window contact that triggers in the middle of the night, the motion detector in the garage, the smoke detector in the garden shed, or the water detector in the laundry room: with the alarm siren, you and your neighbors will be alerted immediately and can respond quickly. For quick identification of the current alarm scenario, four individual warning tones and three additional (quieter) signal tones are available. The latter are particularly suitable as a doorbell, feedback when activating the alarm mode, or for numerous other scenarios. Additionally, a red LED serves as a visual alarm and information signal.
