If the mute function is active, the LED will flash once approximately every

If, after this period, fire smoke is still detected in the smoke measuring chamber,
the acoustic alarm will sound again.
Only activate the alarm mute function when you are

that you can exclude a cause of fire!
Care and maintenance
What to do in case of false alarm?
Possible causes of false alarm include: Welding and cutting, soldering and other hot
work, sawing and grinding, dust created from building work, e.g. cleaning, extreme
electromagnetic effects, changes in temperature which lead to condensation in the
alarm as well as small insects and pollen.
• If a false alarm is being caused by work close to the device, it should be
temporarily covered up or removed. Upon completion of the work, it is
imperative, however, that the device be returned to its original opera-
ting state and be checked!
Cleaning
The operation of every installed smoke alarm must be regularly checked and
kept safe through maintenance measures in accordance with German DIN 14676
application standards. This includes an inspection at least once every 12 months ±
3 months, including maintenance and checking the performance of the warning
signals. The results and measures taken should be documented accordingly.
• Dust covered alarms must be cleaned. Dust deposits in the alarm’s air vents can
be sucked up.
• Dust can be removed with a brush if required.
• The surface area can be cleaned with a slightly damp and soapy cloth.
• Take care that no liquids get into the apparatus! Do not clean device in a dishwasher!
