Rated 4 out of 5 by from A1 Mains Battery Back Up Optical Smoke Detectors These are one of the best smoke detectors on the market, they do require hard wiring but by using the RF base (sold separately) you can achieve a linked system without linked cabling NB that you do need a common live,neutral and CPC (AKA earth) at each unit. The only one negative point I would make is that the terminals are little tricky/tight when cabling uop using linked wiring. Other than that excellent product. Come with it own base where wire can be enclosed safely, some umits on the market don't and you need to purchase the base as a extra item

Rated 5 out of 5 by from Easy to install - replacing Ionisation version My electrician recommended 'ToolStation' for this product as a replacement for the Aico Ei141RC Ionisation Smoke Alarm. So the base units were already wired in and I simply had to unclip & slide off the old units and replace with these new ones. Extremely easy and quick; very satisfied!

Rated 5 out of 5 by from Easy to fit Occupant had left the hob on so alarm was going off at midnight, due to heat. Occupant couldn't turn it off, so smashed it with a broom handle and cut the mains wires that it then hung from out of the ceiling with scissors! This new unit comes complete with a new base, fortunately, which was very easy to screw to the ceiling, and very easy to wire (access available from both sides, i.e. top and bottom, due to a cunninhg lift flap). And then the new smoke/heat detector just slides into the base. Tested on battery power alone (battery supplied was one year old already, but still 4 years to run), then tested on mains, faultless. Simple, quick, and very neat job. Stern warning administered to occupant...
