Spurious alarms often have the following causes:
• Dust due to construction work or cleaning work,
• Sawing and grinding work,
• Steam,
• Cooking vapours,
• Temperature fluctuation (= condensation of humidity),
• Welding and separation work,
• Soldering and other high-temperature processes.

tors, please observe the information in the section ”What to do
