Stiftung Warentest: Smoke detector in the security test

Stiftung Warentest tested 18 smoke detectors: Many are not good at all - the most expensive one even failed completely in the test. In our test summary, we will show you which smoke detector you can rely on in an emergency and which bargains are really safe.

Product test: Good smoke detectors do not have to be expensive

From 2016, the smoke detector obligation applies in some federal states. So it's high time to retrofit:

• The test winner Ei lectronics Ei650 with the grade 2.2 costs just 23 euros: It warns reliably when there is a fire and rarely has a false alarm.
• The Ei650 is particularly easy to attach and has survived the fall from a height of 2.5 meters without damage. It contains a battery that lasts about 10 years. You can find out whether it still works with a broomstick that you press against the test button.

Smoke detector in second place almost as good

• The second-placed Detectomat HDv Sensys also reliably warns of fire. You can already buy it for 21 euros.
• False alarms are also rare here and if they are, you can easily switch them off again with the broomstick. The difference to the test winner is in the declaration: The manufacturer's guarantee period is missing. Nevertheless, goods test awarded a 2.3.

Ei Electronics shows: Why smoke detectors are so important

Product test: Networked smoke detectors in the test

Radio smoke detectors are particularly ideal for large houses: All detectors are connected to each other by radio. Noticed a smoke, everyone sounds the alarm. This also warns the children upstairs if there is a fire in the basement. Here you will find an overview of all the advantages.

• Ei Electronics is again the test winner among the networked smoke detectors: The Ei 650 M model costs just 80 euros, but is reliable like no other.
• The radio connection could not harm reinforced concrete in the test. The Ei 650 M is highly reliable, loud and robust - that's the verdict of Warentest. Grade: 2.2.
• All details can be found at test.de.

Saving tip: Smoke detector in second place is 30 euros cheaper

With the second placed smoke detector you save 30 euros each:

• The networked Angel ST 630 costs around 50 euros each and is almost as good (grade 2.3).
• There is only a loud trial alarm once during setup. In the test, this led to a small devaluation. You can save money here ...
• Tip: We help you to attach the smoke detectors.
