Combining state-of-the-art technology with a modern design, the WisuAlarm Wireless Link Smoke Detector provides a stylish solution to protecting your home. Suitable for all domestic properties, the detector is designed to be a stand-alone unit or can be connected wirelessly to up to 24 other WisuAlarm wireless devices (smoke detectors, heat detectors or CO detectors) within the property, ensuring if one unit activates the loud 83db sounder will sound throughout. As an added bonus, by adding the optional Internet Gateway anyone with the free App enabled will be kept informed of any activations from the system. Adopting a new split-spectrum sensor technology and a built-in high-volume sounder, our lithium battery-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.
