Selecting the mounting location
NOTICE: It is recommended that you install multi-
ple smoke detectors in your residence or building.
In order to provide minimal protection, it is
recommended that multi-floor buildings have one
smoke detector installed per floor.
WARNUNG: The smoke detector should be
mounted on the pathways to the bedrooms (stair-
ways, hallways, entry ways, etc.). Please make sure
that it can be heard well from the bedrooms. If an
unfavourable location is chosen, the smoke
detector can be largely ineffective in the case of a
fire. This can reduce the time needed to get to
safety in the event of a fire, endangering your life.
