Rated 5 out of 5 by Good Replacement Product Good product at a good price. Replaced old ones without having to change plug or base plate, so took only a couple of minutes. 17 Oct 2015
Rated 5 out of 5 by easy to fit Great units. Bought these to replace Two which were fitted over twenty years ago, to my surprise they are a direct swap which saved me altering the mains plug. Well pleased, even came with a 9Volt Battery and 5 years warranty. Also a good price 7 Oct 2015
Rated 5 out of 5 by Easy to install mains Smoke Al Reasonably priced smoke alarm for use with mains power and has a backup 9V battery. Easy to install with clear instructions. Three connectors: Brown, Blue, White (Live, Nutral and Interlink). Remember earth should not be connected! Easy installation and if you are replacing an existing alarm then it shouldn't take more than 5mins. 28 Jul 2015
