Abstract
Millions of automatic fire detectors - especially ionisation smoke detectors - have detected fires quite reliably at a very early stage. For this purpose, smoke detectors are designed to sense the environmental conditions, but by doing so they are also influenced by these conditions. Detectors can also be put into alarm by environmental factors - in this case we call it a false alarm. Each false alarm can be associated with a probable source - such as contamination, insects, influence of temperature, wind, humidity, corrosion, strikes of lightning, electromagnetic influence or smoke-like symptoms such as vapor from welding operations, etc.
