SAFETY CAN BE BEAUTIFUL
A beautiful smoke alarm has no need to be hidden out of sight on the ceiling. A subtle yet stylish piece can be as good in attracting admiring eyes as the design sofa in your living room. We at Jalo Helsinki want people to fall in love with their smoke alarms and let this essential everyday object find its way into as many homes as possible.
We asked two of the top designers in Finland to update the smoke alarm to the present day. Harri Koskinen is known for his pure and innovative design idiom, and his creation, Kupu, is no exception. Paola Suhonen captured our hearts with her original style and rock chick attitude. The result, Lento, is as wild as its creator.
We were not satisfied with just making the smoke alarm more attractive-looking, but we also enhanced its usability. Installing takes mere seconds with no need for screws or a power drill. There are no tiny push buttons, but the whole external casing acts as a press switch for silencing false alarms and testing the performance of the product.
Let Jalo protect what you love.
