Please note: Specific requirements for smoke alarm and/or carbon monoxide alarm installation vary based on the country, region, property type and use of the property. Please find links here to helpful resources about certain UK local regulations and codes.

Please note: The alarm should not be installed in locations where the normal ambient temperature is below 4°C or exceeds 38 °C. Humidity range: 20% RH to 80% RH (non-condensing).

We like it because

it looks for fast-burning fires, smouldering fires, and carbon monoxide. It tells you where the danger is and alerts your phone in case you’re not home.
