Really good quality heat alarm which makes a super loud noise when activated. It's wireless and just sticks to the ceiling so is really easy to install. We recently had our house rewired and I didn't realise that the minimum safety standard is now heat alarms in certain rooms/areas rather than smoke alarms, so this has been perfect to help us comply with safety rules and hopefully keep our family safer in the event of an emergency.

The kit covers a 3 bedroom house, bathroom and kitchen nicely. The duality of smoke and heat detectors is useful and the carbon monoxide detector is essential. A complete package. A dry run test shows that the alarms link together giving good warning throughout the house.

Smoke, heat and CO - pretty much all covered. Would be nice if Wifi or smart enable to trigger more devices. Just need to find suitable spots, as per suggested by the instruction. No more further setting, only the test button- and coverage of up to 100m. Built in battery lasts about 10 years - which is not changeable. Good clear digital display showing the CO concentration. Very loud individually and easily cover a 3-4 bed room house/apartment. One convenient set for easy set up and pretty reliable for being interlinked.

This Wireless Interlinked Smoke, Heat and Carbon Monoxide kit is good value and good quality We bought a magnetic fixing kit which made installing them easier; although installation is simple anyway with the provided kit As they are linked, they all sound at once when alerted which can be a bit noisy and a little disconcerting but the remote silences them immediately Definitely a good and necessary pack for any home Recommended

These units come pre connected to each other to make installation super easy. They have built in batteries that should last for 10 years making this quite an economical package. Unlike other detectors that work individually as soon as one of these detectors is activated all 5 will sound alerting everyone in the house wherever they may be.

This smoke alarm is fairly small in size but well built and looks pretty good overall. Installation was super easy with a template for screws or self-adhesive tape options (both provided). Alarm battery is supposedly 10 years long so this is very assuring. Although only time will tell if it actually lasts 10 years or not. A great thing about this smoke alarm is that you can link multiple units with each other which can be really beneficial. I have not tested this functionality yet but it suggests that you can link with just press of a button.
