Alarm silent mode
Once the device is in alarm mode, the alarm sound
can be deactivated for approx. 10 minutes by press-
ing the test/reset button.
When the device is in silent mode, the red LED light
will continue to flash every 8 seconds to show that
the alarm is still in active mode.
If smoke is still detected in the smoke measure
chamber once the approx. 10 minute silent period
has ended, the audible alarm will sound again.
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 household dust and small insects.
• 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
operating 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 applica-
tion standards.
This includes an inspection at least once every 12 months ± 3 months, including
maintenance and checking the performance of the warning signals.
