The KUPU10, designed by Harri Koskinen, is a battery-operated smoke detector for home use. It comes with an integrated, non-replaceable lithium metal battery that lasts up to 10 years, which corresponds to the maximum recommended lifespan of smoke detectors. The automatic activation upon installation and the absence of battery changes ensure the highest safety for your home for up to 10 years.

In addition to the mounting plate included for easy installation, the automatic self-test function and the test function that can be activated across the entire front are further features of this life-saving device.

KUPU smoke detectors use photoelectric detection methods to differentiate smoke from various fire sources. The photoelectric (optical) detector is triggered when infrared rays within the housing are deflected by smoke particles and reach the sensitive sensor. The integrated self-test function guarantees a hassle-free product lifespan of up to 10 years. When smoke is detected, the device emits a loud and continuous alarm sound to alert residents and neighbors.

To prevent false alarms, the smoke detector conducts regular checks to measure air quality. However, if a false alarm does occur, you can temporarily deactivate the smoke detector using the convenient mute function for 8 minutes. If strong smoke is detected during the mute period, the alarm will reactivate for your safety.

When the smoke detector reaches the end of its lifespan, it will independently warn you with short beeping sounds for up to one month about the weak batteries.
