KlikAanKlikUit smoke detectors will inform you of smoke development in your home anytime, anywhere. These fire alarms will sound a loud alarm and send a notification via the Trust app. You'll also get a notification when the battery is almost empty this way, so you avoid the beeps of a smoke detector. It's possible to mount the small detectors anywhere with the adhesive strips. You won't have any drill holes when you replace the detectors after 10 years.
