Ei Electronics Smoke alarm device can be converted to radio, networkable battery-operated

The Ei650W smoke detector is reliable! Whether operating independently or connected with other Ei Electronics components, this detector impresses with its highest reliability – from the moment it is activated until the end of its lifespan. To ensure alarm coverage throughout the house, the smoke detector can optionally be connected via radio; the Ei600MRF radio module is sold separately. Thanks to its long-lasting 10-year battery, the smoke detector reliably protects against fire hazards for the entire 10-year lifespan. The device, manufactured in the EU, checks every 10 seconds for the presence of smoke particles in the air. As soon as it detects smoke, the smoke detector immediately warns with its integrated loud 85 dB(A) piezo alarm. And because nothing is more annoying than frequent false alarms, the Ei650 is equipped with contamination compensation to prevent disruptive incidents. Additionally, it operates without an LED or distracting flashing light, making it completely suitable for bedrooms.
