This is a new type of ultra-thin smoke alarm. Compared to traditional smoke alarms, the thickness of the product has been reduced by about 40%, to just 23.5mm, which makes the product more discreet. It becomes the invisible guardian of the family. The product is designed in a minimalist style with an integrated large button for easy operation and the use of a “home” element to give the user a warm sense of security. With industry-leading self-test and vapor-proof features against false alarm, it is more reliable and safer than traditional smoke alarms.
