Q. Does this alarm conform to BS 5446 part 1 as recommended by the Fire Service?

BS 5446-1:2000 was withdrawn in 2008 and replaced by BS EN 14604:2005 to conform with European standards. All of our alarms containing a smoke detector (smoke only, smoke & heat, smoke & CO) are fully compliant with BS EN 14604:2005. They also comply with any other relevant standards relating to their other detection capabilities.

Great product, shame the sticky pads were not as good Gave up using the sticky pads as they were a bit rubbish. The product itself was fine. Arrived quickly, no dramas. Would recommend Safelincs and would use them again.

It works when press the 'test' button, it fitted easily with two screws, and I hope we never get to know that it works when there's smoke around!! Fitted in the loft. Every loft that has working electrical kit in it should have a smoke alarm fitted. Now ours has!
