Protect your home and loved ones with this smoke alarm and heat alarm kit from the Kidde KF-R Series. This bundle consists of 2 smoke alarms and 1 heat alarm to provide all round smoke detection for your property. All alarms in this bundle are mains powered with a self-charging 10 year lithium back-up battery, so there is no need to change the battery throughout the lifetime of the alarm and you can be assured that the alarms will continue to work during a mains power failure. The Kidde KF-R range allows for up to 24 alarms or compatible devices to be hardwire interlinked to ensure that if one of the units is activated, all other alarms will sound to provide the earliest warning of fire.

Easy to connect up but for some reason one unit kept beeping.
Swapping the units rounnd caused the beeping to stop but I could not understand why. Units seem ok and the alarms all linked.
