Rated 5 out of 5 by from Great replacement for old Firex Kiddie KF10 units I had an electromagnetic compatibility problem with my two interconnected 3 years old Firex / Kiddle KH10 mains / battery smoke detectors that were falsely activating by a nearby radio transmitter. I contacted FireAngel Tech Dept in Birmingham and they assured me their SW1-R units were fully tested in an EMC lab as being immune from radio transmissions. Once installed this was proved to be correct. The units fitted the existing plaster board internal ceiling mounted dry lining box, so the supplied base plate was adequate. This was fixed using two long standard mains sockets machine screws and then the main unit easily clipped into place. The SW1-R is a very well made mains / battery driven smoke detector which is available from Tool shed at an attractive price.

Rated 4 out of 5 by from Different connection to others This unit this alarm has a connector which needs to be recessed into the ceiling so if replacing a unit with a connection directly to the base a hole has to be made for the connector. Made replacing a little more difficult.

Rated 5 out of 5 by from Great value, clean look and easy to install. Bought to replace old (expired) mains interconnected smoke alarms. I used these with the bases to make my life easier although these are not essential, as there is a mounting base included that the alarms fit into. Note that cables from these are central and you will need choc-blocks (4-pole, LNE and interconnect (if used)) that then need to be shoved up into the ceiling void. The optional base (10991) means that the wiring is within the unit and off-centre, plus there is a better seal on the ceiling, which is handy when replacing old units rather than just fitting new. Very clean design; back-up battery and fixings included as you'd expect. Excellent value.
