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BS 5446-1:2000 was withdrawn in 2008 and replaced by BS EN 14604:2005 to conform with European standards.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 quality service and product I got a free upgrade and the service was fantastic! My detector was ready to use and it beeped upstairs when i burnt the toast downstairs. It isn't unreasonable though, it doesn't go off all the time only when the threat is desent. I am very happy with this buy, i will shop here again and buy the same or similar product.
