If it does go off inadvertently, the large, central test/mute button makes it easy to silence, saving your ears from a thrashing. As with the Pro Connected, it buys you ten minutes to clear the air, while a “sleep easy” function gets you eight hours of quiet if you press the button once the low battery warning starts. Little touches such as this elevate the ST-622Q above your run-of-the-mill smoke alarms, making it one of the best options for most households.

An alarm installed inside the kitchen must be a heat alarm rather than a smoke alarm. Just outside a kitchen (eg in hall or dining room) an optical smoke alarm or, even better, a combined smoke and heat alarm should be installed, as these are less sensitive to false alarm.

Smoke detectors use sensors to detect airborne smoke particles. Different types of smoke detectors use different technology to sense particles.We test smoke alarms using an aerosol tester, sprayed in the direction of the alarm for up to five seconds from a distance of 30cm. If the alarm doesn’t respond within four seconds, we don’t recommend it. Having completed this functional test, we take a careful look at any controls, screens, or indicators to see how clear and effective these are. Ionization smoke detectors notice tiny burning particles. This type of detector is really good at sensing fires that flare up rapidly. The downside to an ionization smoke detector is that it can’t detect smoldering fires as effectively. Ionization detectors also tend to have problems with false alarms.
