During the 15 minute deactivation period, the smoke detector
does not recognise any smoke and therefore does not trigger
any alarms.
After expiry of the deactivation, the smoke detector automatically returns
to standard operation mode.
Spurious alarms
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.
!
In order to avoid spurious alarms and/or soiling the smoke detec-
tors, please observe the information in the section ”What to do
when carrying out renovation work?”
