Fireangel TST-622Q Smoke Alarm, 2 Pack

Product Information

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. Different makes and models will be slower or faster to detect smoke coming through and have different alarms working at different volumes. This and the 10-year sealed-in battery means they’re compliant with recent changes to Scottish legislation, and that you won’t miss out on an alarm if you live in a larger property, have a hearing impairment or spend a lot of time with the TV blaring or your headphones on. Cleverly, the alarm starts quietly during testing, only ramping up to the full 85dB racket if you hold the test button for five seconds.

The FireAngel HT630 is a good, affordable, well-regarded unit, backed by a ten-year warranty and powered by a sealed-in Lithium battery with a ten-year lifespan. It also detects carbon monoxide and can even tell your Nest thermostat to turn off the boiler if it detects a leak. In 2022, Scotland added further legal requirements that smoke alarms fitted in a home be interlinked, so that if one goes off, they all go off.The next thing that happens is they replace the battery for the toy but not the one they have removed from the smoke alarm. This Twin pack contains 2x FireAngel smoke alarms which use Thermoptek multi-sensor technology which pairs the very latest in optical sensing with thermal enhancement, and when compared to single sensor alarms reacts to fire in under half of the time.

Key specs – Type: Split-spectrum optical; Battery type: 6 x AA lithium; Display: LED ring indicator; Alarm volume: 85dB; Connectivity: 802. In fact, most homes require more than one smoke alarm, alongside detectors for carbon monoxide (CO) and heat. And, like FireAngel’s Thermoptek-powered smoke alarms, it has a hush button you can push should it go off unnecessarily, sparing you an 85dB ear bashing.

However, the difference isn’t huge, and they’re less likely to be triggered accidentally when cooking.
