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.
