I live in a 3 storey block of flats (17 flats) that was built circa 1970. There's a mis-mash of battery operated smoke alarms in the common areas that have been put in over the years by the resident's management comittee. I am now a memeber the said comittee and we have decided to replace all of the old alarms with the Dicom ionisation 10 year battery alarms.
However I would also like to add, one to each floor, probably around the stairwell area, wireless smoke alarms. so hopefully if one of these alarms is triggered on one floor the other two will also sound on the other floors.
The common area floors are tiles on top of concrete (although now carpeted as well), the walls are unplastered brickwork, and the stairs and landings are also concrete. There are no firedoors between floors, the stairs and landings are all open plan.
Have spotted these wireless units (

Are there any problems that can occur with this type of alarm ie alarms set off by other spurious RF signals, or shorter battery life due to being wireless?
