The Somfy Protect Outdoor Siren is an extension for your Somfy One, Somfy One + and Somfy Home Alarm. At the moment that a burglary is detected, a sound signal of 110 dB will sound. The sound switches off automatically after 3 minutes. Of course in the meantime you have already received a notification via the app on your smartphone (iOS and Android). Does the burglar think about sabotaging the siren? Then he has bad luck. The siren is equipped with tamper detection. The siren operates on 4 alkaline D batteries. When they are nearly empty, you will receive a notification via the app. So you never stand surprises.
Please note: the law and regulations concerning the placement and use of an external siren vary per municipality. In some municipalities it is forbidden to place an outside siren and a permit must be applied for. It is your own responsibility to control it within your municipality. Somfy and Coolblue are not responsible for this.
