the test button. If no sound is produced, the smoke alarm is not functioning properly and must not
be used!
Note on installation
First remove the grey mounting plate by turning it anti-clockwise. On the inside of the mounting
plate there are two opposite arrow markings, one of which is printed with a buzzer logo. When
installing the alarm, make sure that the printed arrow at the height of the buzzer on the
alarm matches.
9. Alarm muting
If the smoke alarm has detected smoke and switched to alarm mode, you can mute the alarm
for a minimum of 5 minutes and a maximum of 15 minutes by pressing the test button. The smoke alarm
then resets automatically and returns to normal operating mode. If there are still smoke particles in the air,
the smoke alarm switches back to alarm mode.
WARNING NOTICE:
Before muting the alarm, the cause
of the alarm must always be identified to ensure that there is no dangerous situation.
10. Weak battery/peaceful sleep
When the battery is low, the smoke alarm indicates this by a repeated beep and flash for a period of
approximately 30 days. WARNING NOTICE: This smoke alarm is equipped with a non-replaceable
battery. Replace the device as soon as possible when this warning message appears! The acoustic
low battery warning signal can be muted for ten hours by pressing the test button. In this mode, the
smoke alarm is still functional and able to detect smoke.
11. Error reporting mode
If the smoke sensor is not functioning correctly, it switches to error reporting mode. Try to clean the
smoke alarm (see the “Maintenance” section), or replace it! If the buzzer is not functioning correctly,
the device switches to buzzer error reporting mode. In this case, please contact the manufacturer
immediately or replace the smoke alarm.
12. Night mode
This smoke alarm has an automatic night mode. In dark rooms, the LED signal is dimmed to avoid
disturbing your night’s rest.
13. Maintenance
• This smoke alarm is equipped with a self-test mechanism. We recommend testing the smoke alarm
manually using the test function at least once every three months. The loud beep confirms that the
smoke alarm is working correctly. Ensure that you are always an arm’s length away from the device
