## Long description

The Jalo Helsinki Kupu 10 is a battery-powered photoelectric smoke alarm designed for domestic use. This upgraded version of the Kupu Original features a sealed 10-year lithium battery and photoelectric (optical) smoke detection for reliable early warning of smoke and fire. The alarm measures approximately 110 mm in diameter and 41 mm in depth and is available in several fabric and chrome finishes.
Advantages
Kupu 10 includes a 10-year sealed lithium battery that eliminates the need for battery replacements during the device’s recommended service life. Installation is quick and tool-free using the included 3M double-sided tape or the supplied mounting screws. The entire surface of the unit functions as a test button, and the alarm offers a silence function and self-diagnostic checks to ensure continued reliability. When smoke is detected, the device emits a continuous alarm louder than 85 dB.
Suitable for
Residential ceilings in homes and apartments
Bedrooms and living spaces
Kitchens and hallways (photoelectric detectors reduce false alarms from cooking compared with ionisation alarms)
Interior spaces where a discreet, design-conscious smoke alarm is preferred
