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
Rated 5 out of 5 by Easy to fit I have fitted these alarms in several rented houses, easy to fit and good all round years. This is a very tight fitting and easy to remove and change battery 5 Jul 2015
Rated 2 out of 5 Poor installation design This alarm looks neat but the cable and plug for installation are badly designed. Firstly the plug is huge so you will have to cut a 32mm hole through your ceiling. Secondly the cable is far too short so even with a junction box directly above it is difficult/impossible to later remove the alarm from below to replace the backup battery. You can get a surface mount box to effectively turn the base into a ceiling rose but this is very ugly. Instead we got the 700 series which includes a proper base for mains installation requiring a hole in the ceiling only for the cable(s). This also looks way better than a surface mount box and is lower profile. In addition the 700 series has a push fit mechanism for the alarm into the base which is also easier to use. 3 Jul 2015

One of the reviews says do not connect the earth, is that right? Why would that be?
