Replacement for Kidde KF20 Mains Powered Smoke Alarm

The Kidde KF20 is a mains-powered optical smoke alarm with a 9V backup battery. The replacement Kidde alarm utilises the same baseplate and connector plug to provide an easy swap-out. Featuring a 6 year manufacturer's warranty, it can be hardwire interlinked with existing Kidde Firex alarms, so you can replace units one at a time without changing the whole system.

Optical smoke detection is much less likely to give false alarms from everyday fumes such as cooking vapours and humidity. This makes it ideal for hallways, bedrooms, landings and living areas.
