Features and benefits

This FireAngel smoke alarm uses Thermoptek multi-sensor technology which pairs the very latest in optical sensing with thermal enhancement, and when compared to single sensor alarms reacts to fire in under half of the time. It comes with a sealed for life battery, meaning no need to replace, and is simple to install. This alarm cannot be connected to other alarms in your home.

  • FireAngel's Thermoptek sensor will detect fires in half the time of standard optical smoke alarms, giving you extra time to react and protect your family
  • Use the large central button to easily test and silence your alarm using a sweeping brush from below - no need for a step-ladder!
  • The sealed battery will protect you for the life of the alarm without needing to be changed - simply replace the full unit when you hear the end of life alert
  • Install on landings and in hallways, bedrooms and living spaces. For fire detection in your kitchen, attic or garage install a heat alarm
  • No need for re-wiring - this alarm can be installed simply and quickly using the two screws and base plate provided, and doesn't require an electrician
