Fire prevention drills

The heat detector emits a powerful 85 dB sound when the air temperature is within the range of heat sensitivity. This now requires your full attention and quick action.
Develop an escape plan with your family to be prepared for such situations. Involve all family members and conduct regular drills.
Explain to your family what it means when the alarm goes off.
Specify two exits. As well as an escape route outside for each room.
Tell all your family members to first touch a door and use an alternative exit if it is hot; a hot door may not be opened under any circumstances.
Inform all your family members that they must crawl on the floor to remain below the smoke, steam, and gases.
Specify a safe meeting point outside the building.

In case of fire

Do not panic. Remain calm.
Exit the building as quickly as possible. Feel whether the doors are hot. If necessary, use another escape route. Crawl on the floor, do not take anything with you.
Go to the meeting point outside the building.
Contact the Fire Service as soon as you have left the location of the fire.
Do not return to the burning building. Wait until the fire is extinguished.
These tips aid you in case of a fire. Follow fire regulations and avoid dangerous situations to reduce the risk of a fire.

Silence mode
