Combining state-of-the-art technology with a modern design, the WisuAlarm mains-powered smoke detector provides a stylish solution to protecting your home. Suitable for all domestic properties, holiday homes and private lets the detector can be used as a stand-alone unit or can be connected by wire to other WisuAlarm devices (smoke detectors or heat detectors) within the property, ensuring if one unit activates the loud 83db sounder will sound throughout. By installing the optional wireless connection module the unit can then be connected wirelessly to other WisuAlarm wireless-enabled devices while still been connected by cable to non-wireless devices (Hybrid system) As an added bonus, the wireless module, when linked with the Internet Gateway allows anyone with the free App enabled, to be kept informed of any activations from the detector while also been able to check the detector status for faults, remaining battery life etc. Adopting a new split-spectrum sensor technology and a built-in high-volume sounder, our mains-powered smoke alarm responds quickly to smoke while giving a stable performance and low false alarms. Once the surrounding smoke concentration reaches the alarm value, the unit will sound continuously until reset.
