Replacing the battery

• If the battery is low, the smoke detector beeps once every 43 seconds (for up

to 30 days) to remind you to replace the battery.

• You must change this battery when you hear this signal.

• Loosen the detector from the detector base by turning it in an anticlockwise

direction, remove the old battery and insert a new battery into the detector with

the correct polarity (see diagram 1).

• Even so, the smoke detector remains functional in this condition.

• You must test the smoke detector each time you change the battery.

• Carry out the test as detailed above.

Note

To ensure a long service life and reliable operation, we recommend using

the following high-quality batteries:

• EVE CR123A, PAIRDEER CR123A

Alarms and error signals

When the alarm threshold is exceeded, a loud alarm sounds.

• The alarm continues sounding as long as there is smoke in the detection chamber.

• The alarm is only switched off when there is no more smoke in the detection

chamber.

What to do if there is a false alarm?

A false alarm can occur due to very high air humidity, the build-up of smoke whilst

cooking or a large build-up of dust, or smallest insects for example.

• If the alarm sounds, first get yourself to safety. If you are certain that it is a false

alarm, you can switch the alarm mute for about 9 minutes by pressing the

test/stop button.

• The smoke detector will switch off automatically once the smoke particles have

left the smoke chamber inside the detector.
