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. 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.
