Ei Electronics Ei650W-1XD langaton verkotettava optinen palovaroitin 10 vuoden paristolla, valkoinen, 115 mm

Traditional smoke alarms often fail to alert occupants in distant rooms or on other floors, leaving critical gaps in fire protection. The Ei Electronics Ei650W-1XD solves this by adding wireless interconnection to a battery-powered optical smoke alarm, so when one unit detects smoke, all linked alarms sound simultaneously—providing whole-home coverage without complex wiring.
