Product Information

The Kidde Firex KF30R is a mains powered thermal heat alarm with a sealed self-charging lithium back-up battery, designed to last the full lifespan of the alarm without any need for battery changes. Heat alarms can be used in areas of the home which are humid or dusty where optical or ionisation smoke alarms may trigger false alarms such as in kitchens, loft spaces and garages.

The Kidde KF30R can be hard-wire interlinked with up to 23 other Kidde mains powered alarms which will create an interconnected system where if one alarm is activated, all other connected alarms will sound.

The KF series alarms are vastly improved over previous Firex alarms, offering 70% lower energy consumption and an enhanced low profile design.

The Kidde KF30R is kitemark certified to BS5446 Part 2: 2003, CE marked and has a 6 year warranty.
