Display and functions
Self-test with automatic error message
The smoke alarm will perform a periodic self-test and it is able to recalibrate the
sensitivity of the smoke measure chamber automatically in case of contamina-
tion. If the alarm's sensitivity trigger fails under the minimum required threshold
level (e.g. due to excessive contamination of the smoke measure chamber), the unit
will beep once every 40 seconds.
If the error message does not clear upon cleaning of the alarm, then
the alarm should be immediately replaced (see chapter entitled 'Care
and maintenance')!
Alarm mode
Upon detection of smoke, a loud, pulsating alarm tone will sound and the red LED
light will flash simultaneously at short intervals. In this case, proceed as described
under the chapter entitled 'Emergency procedure when alarm sounds'.
Alarm mute function
Once the device is in alarm mode, the alarm sound
can be deactivated for approx. 11 minutes by
pressing the test / stop button.
If the mute function is active, the red LED will
flash 2x per second.
If, after this 11-minute mute 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
absolutely sure that you can exclude a cause of fire!

Alarm buffer
This function can be used to identify a smoke detector that has previously triggered
an alarm and returned to normal mode.
In this case, the green LED flashes three times every 40 seconds. After triggering, the
alarm is displayed for 24 hours. The indicator is then stopped to conserve battery
power. If the battery is already low, this indicator is not activated.
The alarm memory function can be stopped prematurely by pressing the test button.
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 or blown out.
• Dust can be removed with a brush if required.
