Forget battery replacement with a Kidde 10-year sealed smoke alarm. Just fix to the ceiling with the fixings included and you are protected. Being a sealed unit, it also stops people removing the battery without you knowing making it ideal for holiday lettings. An amazing 10-year warranty, end of life alarm and hush button adds peace of mind.
Suitable for bedrooms, living rooms, hallways and landings
Do not use in or near to a kitchen or shower room (ie, keep it away from smoke and steam)
Fixing requires two little screws and wallplugs (included) to screw to ceiling or use sticky pads |
