How does a smoke detector work?

Smoke detectors can be divided into three different types, which work in different ways. We explain the photo-optical smoke detector, the thermo-optical smoke detector and the ionization smoke detector.

Do not place your smoke detector in attic rooms at the top of the roof, but at least 0.5 m away from the slope. Air cushions often obstruct the rise of the smoke to the ceiling!
