Mandatory installation of smoke detectors
600 fire fatalities, approximately 6,000 injuries and 4 billion euros in material damage annually – in light of these figures, it is astonishing that standard regulations for the mandatory installation of smoke detectors are not in force across Germany and Austria. Nevertheless, thirteen German federal states have adopted a mandatory installation of smoke detectors into their state building codes. In Austria, eight federal states enforce the mandatory installation of smoke detectors. This means: At least new and renovated constructions must be equipped with suitable smoke alarm devices in bedrooms, children's rooms, and hallways which serve as rescue routes to the outside. There are various transitional regulations for existing residences. They must then also be equipped accordingly.
The Gira smoke alarm device has optimum detection characteristics when mounted on the ceiling in the middle of the room. If this is not possible, observe a minimum distance of 50 cm to the wall. A smoke alarm device can monitor a room with a maximum area of 60 m² and a maximum room height of 4.50 m. Where smoke alarm devices should be positioned to guarantee minimum protection varies depending on the design of the house or flat. In single-story flats, the hallway used most frequently in case of fire should be equipped at minimum. In multi-story buildings, the hallways of each story must be included. However, equipping all the rooms is recommended for optimum protection.
