Battery powered wireless interconnected photoelectric smoke alarm AT-S206W with DC 3V supply and 3-year battery life. Operates on 868 MHz with up to 200 units interlinked and >250 m open-air transmission range, providing synchronized alarm coverage in larger homes and commercial buildings.
The AT-S206W is a wireless interconnected photoelectric smoke alarm designed for multi-room fire protection. Using a photoelectric sensing chamber, it responds quickly to smouldering and flaming fires and activates a loud ≥85 dB alarm at 3 m when smoke is detected.
Powered by DC 3 V with a 10-year battery life, the AT-S206W uses 868 MHz wireless connectivity to link up to 200 units in one system. When any detector in the network goes into alarm, all interconnected units sound simultaneously, providing full-area warning. With a coverage area of 20–40 m² per unit and a transmission range over 250 m in open air, it is suitable for medium and large homes, dormitories, offices and similar applications.
The compact ceiling-mount design operates in temperatures from 0–55°C and humidity up to 85% RH, making the AT-S206W an effective and easy-to-install solution for wireless fire detection.
