Care and maintenance
What should you do in the event of a false alarm?
Possible reasons for a false alarm are: Welding and cutting work, soldering
and other high-temperature work, sawing and grinding, dust from
construction work or cleaning, extreme electromagnetic effects, and
temperature fluctuations which lead to condensation of the humidity in the
detector.

If work which could cause false alarms is being done near
the detector, the detector should be covered or removed
temporarily. After work is completed, however, it is
essential to restore and test the functionality.
Cleaning
According to German application standard DIN 14676, the functionality of every
installed smoke alarm device must be regularly tested and ensured with
maintenance and repair work.
This consists of an inspection at least once every 12 ± 3 months including
maintenance and function checks of the warning signals.
The results of these measures must be documented.
