Do not open doors without first checking the surface. Do not open a door if it is hot or
you see smoke under it. Use an alternative escape route. If the surface is cool, push
against it with your shoulder, slightly open it and be prepared to close it again if there
is heat, smoke or fire behind it.
If there is smoke in the air, keep close to the floor and breathe through a damp cloth
if possible.
Close the doors after leaving the room.
Once you have left the building, go to the agreed assembly point and do not go back
inside.
Call the fire brigade from outside the burning building.
Notify the fire brigade of the situation inside the building.
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, for example.
If the alarm sounds, first get yourself to safety. If you are certain that it is a false
alarm, you can mute the alarm tone by pressing the test button. The alarm will
continue to be indicated optically by the flashing LED.
The smoke detector will switch off automatically once the smoke particles have left
the smoke chamber inside the detector.
Putting into operation
For recommended installation locations, see diagram 
