Real-time alerts can be sent straight to your connected smartphone, so even if you aren’t at home, you’ll be notified of any issues. When you are at home, you’ll clearly be able to hear the 85 dB alarm from 3m away. Their distinguishing feature is the fact that they can be linked to other alarms, both heat and smoke alarms, so that when one senses danger they all sound. Some smart models sound an alarm on your smartphone and through the alarm itself when triggered – this is the most helpful kind of smart alarm. All of these concentrations are bad enough when you’re awake and realise that something isn’t quite right – especially if others are feeling a similar effect – but if you’re asleep, you may wake up with a severe headache and nausea and be incapable of even crawling for fresh air. Worse, you might not even wake up at all. Why should I be concerned? The Nest Protect passed our sealed incense test with flying colours: the smoke alarm went off first, followed by the CO alarm five minutes later; according to the app, the CO level was 414ppm and increasing. We can’t think of a better CO currently alarm on the market, particularly as it also detects smoke.electrochemical. The advantage of this type of sensor is that it allows not only detecting smoke but also measuring the concentration of gasses, which makes them absolutely a must for private houses and other premises that use the gas heating system.

It is smart, so can alert your phone if there are any issues. This can range from a power issue or sensor failure to smoke or carbon monoxide being detected. It will also tell you where the problem is, and Nest Protect will let you know even if you are out. You can also silence it from your phone should you wish. 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. So if you’re out of your home and not near your phone when the messages come through, you’ll have no way of knowing the alarm was sounding. If you own a Nest smoke and CO alarm, you will be able to continue to use it but it will need to be in addition to interlinked smoke and heat alarms. Unlike other CO detectors, the Nest notifies you (and anyone else who has registered) with a notification on your mobile device, even if you’re in another country. It also does the same for smoke. The main unit also speaks a warning in a calm English female voice when it detects smoke or CO in a room. If the CO levels are slowly increasing, the voice will warn you before setting off the alarm. But if CO levels become dangerously high, the centre lamp glows red and a very loud, high-pitched beep is emitted along with a spoken warning letting you know which room is affected. You can temporarily cancel any alarms by holding the “Stop” button on the app or by pressing the unit’s central button.
