Unbranded SS-168 / General Purpose smoke alarm review

Product alert

Don't Buy this smoke alarm – it failed to detect smoke in seven-out-of-eight of our fire tests

When set the task of detecting smoke from fires fuelled by wood, plastics, cotton and solvents, this unbranded and unreliable product – sometimes known as the SS-168 - failed to sound in all-but-one of our eight fire tests.

It’s one of the most unresponsive and potentially dangerous alarms we’ve seen and in our tests, we found it unable to reliably detect smoke and that’s why we’ve made it a Don’t Buy.

This alarm failed seven out of eight of our smoke tests and that’s why it’s a Don’t Buy. It’s sometimes listed as the SS-168 or as a ‘General Purpose smoke alarm’ and it can often also be found unbranded and for sale on sites such as Ebay. But its results in our tests are a real worry for us – this alarm can’t be relied upon to detect smoke and we’ve made it a Don’t Buy to warn you off from buying it.
