Because the sense of smell at night asleep, waking most of the first, if it is too late: through the dense smoke lose affected the orientation and can no longer lead time to safety - the toxic smoke gases already after three breaths to unconsciousness and death within a short period of time. Most fires are not caused by negligence: technical defects such as cable are one of the main causes of fire at any time without warning can occur. The photoelectric ABUS smoke detector already detects the smallest smoke particles and warns residents with a loud alarm at an early stage and effectively against a resulting fire. The detection range of the smoke detector is up to 40 m² and is limited to the room in which it is mounted. For optimal protection, the smoke detector in the hall, the stairways, living room and bedroom recommended. Unwanted alarms (through disturbances such as dust or water vapor) can be simply and easily by pressing the large-scale test button can be muted. Important Notes on installation and battery life. And the children's rooms as well as in apartments must be sleeping rooms, corridors, via the rescue routes from living rooms, at least one smoke detector. The smoke detector must be installed (or appropriate) and operated in such a way that fire smoke recognized at an early stage and is reported. A stationary 3V lithium battery guarantees a reliable operation and long life of the smoke detector. The proper function of the detector should be regularly checked by pressing the large-scale test button. Malfunctions or a weak battery be signalled optically and acoustically.This text is machine translated.
