Expand your Somfy Alarm Set with the smart Somfy Smoke Detector. Connect the smoke detector to your Somfy box. In case of smoke development, the siren will sound at a sound level of 85 decibels and you will receive a warning via text message or e-mail. For example, it is possible to connect the smoke detector to the roller shutter receiver via the Somfy box. This way the roller shutters open automatically when smoke is generated. You connect up to 12 smoke detectors to 1 Somfy box. Enough to make your entire home fire safe.
