FAQ
What type of sensors do these alarms use?+
These Premium Smoke & Carbon Monoxide Alarms employ photoelectric smoke detection for standard smoke and a dual sensor technology – both ionization and optical – to provide the most accurate carbon monoxide detection available. This combined approach maximizes sensitivity.

These alarms operate on 9V alkaline batteries (not included). It’s recommended to use high-quality alkaline batteries for consistent performance and to minimize the frequency of battery changes.
What is covered by the 10-year manufacturer's warranty?+
The 10-year warranty covers defects in materials and workmanship under normal household use. It does not cover damage resulting from misuse, neglect, or accidental events; refer to the manufacturer’s full warranty details for complete coverage.

Test your Smoke & Carbon Monoxide Alarms at least once a month using the integrated test button. This ensures they are functioning correctly and allows you to familiarise yourself with the alarm's sound.

While these alarms don’t directly integrate with most smart home systems, some third-party devices may offer compatibility through specific integrations – check the manufacturer's website for details.
