Smoke detector obligation in Europe

Only since July 2016 all 16 countries in Germany have set up the general mandatory smoke detection by law.


Why fire detectors are important

In the media there are almost daily reports of fires in residential buildings. Usually there is very little time to escape; smoke and fire are particularly dangerous at night, when the inhabitants are surprised in their sleep. According to the fire brigade, only about four minutes remain for the escape from a burning house. The smoke detection obligation is to prevent this. Already inhaling a lung filling with fire smoke can lead to the worst. In Germany, about 400 people die each year as a result of a fire; most victims are not claimed from the flames, but from fire smoke.

When every minute counts, radio-linked smoke detectors save lives in an emergency and therefore have to function in the event of a fire. Too often people are injured, because the battery of the fire detector is empty or the sensors have failed in case of emergency, and the alarm has not reached the residents in time.

Advantages of radio-linked smoke detectors

Radio-linked smoke detectors, that communicate with each other like the Hager TG 551A are an advantage: radio-linked alarms alert simultaneously when a fire breaks out in one of the rooms. It doesn’t matter in which room heat or smoke has been detected, because the networked smoke alarm sets communicate with each other and also send a push message to your iHaus App in real-time. Even family and loved ones can be alarmed in case of emergency via e-mail or message. If a fire should occur when you are not at home, you will always be aware of the situation and you can inform the fire brigade before any damage is done.

This not only provides more security, but also more efficiency and comfort..
