Battery Back Up
9V Lithium back up supplied

  • 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.

  • Mains-powered heat alarms can be used throughout the home in humid or dusty environments where an optical or ionisation smoke alarm is unsuitable, e.g. kitchens, loft spaces and garages.

  • The Firex range requires installation by a professionally qualified electrician and complies with UK Building Regulations for new housing and associated standards (Grade D BS 5839, Part 6).

  • Interlink with up to 23 Firex hard-wired alarms – all alarms sound if danger is detected

  • Alarm memory – identifies source unit within interconnecting network

  • Combined Test/Hush button allows regular testing of alarm function and can be used to temporarily silence nuisance alarms

  • Auto reset after activation

  • Tamper-resistant locking device – prevents unauthorised removal without the use of a tool

  • Mains operation – 9V Lithium back-up battery supplied as standard
