Which? tests reveal unsafe smoke alarm

New Which? smoke alarm tests have revealed than an expensive, smart smoke alarm is unsafe.

The smoke alarm failed to detect smoke in two fire situations and has been named by Which? as a Don’t Buy.

One sample of the Devolo Home Control Smoke Detector failed to detect smoke at all in a fast-flaming plastics-based fire. When it was after tested with smoke from a solvent-based fire, it again failed to detect any smoke and sound the alarm.

A second sample of the same smoke alarm passed all Which?’s fire tests but just scraped through the flaming plastics fire test, triggering at the very last permitted moment.

Since it has been proven that the alarm might not sound in certain fire scenarios, Which? made it a Don’t Buy.

Devolo responded to the results by telling Which? that safety is its number one concern and that it aims to follow the highest international standards. It also said it is concerned by the results and that the alarm has passed standard safety tests at two certified test labs.

Which? has called on the British Standards Institute (BSI) following the test to make its standards of alarm response-times stricter and only reward alarms that sound more quickly.

It has also recommended running a check weekly to make sure your smoke alarm is primed and ready to let you know when there is a fire.
