Is an expensive smoke detector worth it?

Smoke alarms can save your life - or annoy you beyond belief. It all depends on choosing the right device and, above all, installing it correctly.
On New Year's Eve almost two years ago, I was with good friends in a cottage in Fribourg to ring in the new year together. I could see the entire surrounding mountain landscape from the terrace, there was a sauna in the basement and the rooms were cosily furnished. One of my friends even brought home-shot wild boar for our last evening meal of 2018, which almost proved to be our undoing later on.

A good smoke alarm doesn't have to be expensive
Everyone has to decide for themselves whether this is necessary. The quality features of a smoke alarm are independent of price and networking. Even a very inexpensive model can save your life if a fire starts somewhere in your home while you are sleeping peacefully in bed. When buying any smoke alarm, look out for the following three features
Certification
A reliable smoke alarm is certified in accordance with the EN 14604 standard. This European product standard defines the standards and test procedures for the devices. It ensures that the smoke alarm fulfils the technical requirements. The VdS seal of approval, on the other hand, confirms that the smoke alarm has also been tested for this.
Control functions
The smoke alarm of your choice should have three control functions. A test button to trigger the acoustic warning signal, which you should check monthly. An acoustic indicator as soon as the battery life is coming to an end. And a visual indicator that lets you know whether the device is working properly.
Battery life
The service life of a smoke detector is around ten years, after which it should be replaced. Dust in the control chamber can cause the smoke alarm to stop working. However, the most important thing is that a low battery makes itself audible and lasts for at least 30 days from this point. This gives you enough time to replace the smoke alarm, as most devices have a permanently installed battery.
Where to put it?
The ceiling is the preferred location for both types, as heat rises. It is best to install the detector in the centre of the ceiling, but at least 50 centimetres away from walls and furniture. If your room is larger than 60 square metres, you will need two detectors. If you now follow the instructions in the enclosed operating manual, everything should work smoothly. Even the preparation of wild boar without shrill alarm sounds.
My life in a nutshell? On a quest to broaden my horizon. I love discovering and learning new skills and I see a chance to experience something new in everything – be it travelling, reading, cooking, movies or DIY.
