Keep your home and loved ones safe with the FireAngel ultra-slim optical smoke alarm. Powered by a ten-year sealed tamperproof lithium battery, it provides continuous protection without the hassle of replacement batteries.

Easily mounted on a wall or ceiling, it prominently displays the word "ALARM" when activated. The built-in Sleep Easy feature even lets you silence low battery warnings overnight.

• Optical sensor – fast response to slow-burning fires
• Sealed lithium battery – ten years of tamperproof protection
• Ultra-slim design – blends seamlessly into any room
• Clear display – shows "ALARM" prominently when activated
