Product Information

In Scotland, since February 2022, interlinked smoke and heat alarms have needed to be fitted in all homes. The latter are pricier when you buy for the first time, but you won't have to factor in the expense of replacement battery costs.

Interlinking when one alarm goes off, all the connected detectors are activated. This can be particularly useful in a larger house.Smart smoke alarms are designed to sound the alarm when they detect smoke, as a conventional smoke alarm would. But the unique selling point of a smart smoke alarm is the ability to send alerts to your phone when there’s a fire. All of the major manufacturers (Aico, FireAngel and Kidde) make smoke and heat alarms that will work in combination with one another and we have tested pairs of smoke and heat alarms from each of them.

An interesting by-product of the new breed of smart alarms is the fire-related data being collected, as is the case with Google, which makes the Nest Protect smoke and CO alarm. Google told us that it uses data from its alarms to provide ‘meaningful insights’ for its customers and to improve the product.This could be critical if you’re out when there’s a fire. All of the smart smoke alarms we've tested are optical models. The best smoke alarms you can buy in 2023 1.

The ALN-EN(BLK) smoke chamber is easily removed or replaced for cleaning and utilises a unique improved baffle design which allows smoke to enter the chamber whilst keeping out ambient light. Heat (thermal) alarms detect heat (hot air) instead of smoke. The alarm is triggered when the temperature within the sensor chamber reaches over 58 degrees Celsius – generally when a fire is well established.
