Product Overview

The Kidde KF10 is a mains powered smoke alarm with a 9V back-up battery with the capability of interlinking with other Firex KF series alarms via hardwire. The ionisation-based sensor in the KF10 has been discontinued by Kidde and the ideal alternative is the KF20. The KF20 uses all the same features of the KF10, however adopts the newer optical sensor technology using the same base plate and connector. This ensures the smooth transition from one alarm to the next without the need for an electrician.

Optical smoke detection is much less susceptible to false alarms from everyday fumes such as cooking vapours and natural humidity. This makes them ideal for installation in hallways, bedrooms, landings and living areas, including those rooms adjacent to kitchens, but not within them.

  • Power: 230V mains powered with battery backup
  • Back-up Battery: 9V alkaline battery
  • Warranty: 6 year warranty
  • CE marked and Kitemarked to BS EN 14604: 2005
  • Suitable for installations complying to BS 5839-6: 2019 Grade D2
  • LED indicator
  • Combined Test / Hush button
  • Low battery warning chirp – Silence for 8 hours for a peaceful night
  • Supplied with fixings and a coloured dust cover (ideal for use when decorating)
  • This alarm is also suitable for the updated 2022 Scottish legislation for fire alarms in homes

Please note: The Kidde Firex KF20 is also the replacement for the Kidde 123i / 1239HI, and can be electrically interlinked. However, the new model cannot be used on the old base plates for the 123i / 1239HI as they use different style connector blocks. This means that base plates must be swapped over on those stated models and connectors need to be replaced. Please see our Replacement Compatibility table for a list of alarms that can be replaced with this product.
