A reliable fire alarm system is one of the cornerstones of safety at home. In a fire, every second counts. Therefore, we recommend that you have a smoke detector in every room. With Verisure, you have an advance fire alarm system with interconnected smoke detectors that alert with both signal and voice. If a detector senses smoke, it says: "Warning, fire!" and sends a signal to the other detectors in the system. They reply: "Warning, fire in another room!".
