Features and benefits

  • The optical smoke sensor within the alarm will detect slow smouldering fires rapidly. For the quickest response search for FireAngel Thermoptek.
  • Hardwire interlink multiple SW1-R smoke alarms and HW1-R heat alarms across the home - and when one sounds, they all sound.
  • Supplied with a back-up battery which will alert you to fire during a power cut. This will last approximately 1 year and will then need to be replaced.
  • Use the large central button to easily test and silence your alarm using a sweeping brush from below - no need for a step-ladder!
  • Install on landings and in hallways, bedrooms and living spaces. For fire detection in your kitchen, attic or garage install a heat alarm.
  • Get a peaceful nights' sleep using the SleepEasy mode - it will silence the end of life for 8 hours but if the alarm detects danger it will still alarm in full.
  • Complies with the 2022 Scottish legislation.
