Kidde Firex KF30LL Hard Wired Mains Heat Alarm with Lithium Battery Back-Up


The Kidde KF30LL is Mains-powered heat alarm that can be interlinked with up to 23 other Kidde mains alarms, be they ionisation, optical or heat. Once interlinked, the detection of the relevant danger by an individual unit will sound across all the connected alarms.
