FireAngel ST-622T Thermoptek Smoke Alarm
I received this smoke alarm and was genuinely pleased with it. First off, installation couldn’t have been easier. It’s lightweight and compact, which makes fitting it straightforward. If you don’t want to drill into your ceiling, it’s light enough to attach using adhesive pads (obviously making sure they’re suitable and secure). For anyone who isn’t keen on DIY or making holes in the ceiling, that’s a real plus. The 10-year sealed lithium battery is a big selling point for me. No annual battery changes, no annoying low-battery chirps in the middle of the night after a year — it’s designed to last the full lifespan of the alarm. That alone makes it feel like a fit-and-forget safety upgrade. It uses Thermoptek multi-sensor technology, which combines optical sensing with thermal enhancement. In simple terms, it’s designed to respond quickly to slow smouldering fires as well as fast flaming ones, while reducing false alarms from cooking fumes. So far, no random beeping when making toast, which is always reassuring! The alarm itself is loud and clear when tested, and the test button is easy to press. It feels solid and well made without being bulky. Overall, this is a reliable, fuss-free smoke alarm that does exactly what you want it to do. Easy to install, no battery replacements to worry about, and good peace of mind. I’d happily recommend it.

Reliable smoke alarm recognised by the fire service. Bought to replace previous 10year alarm. Very easy to fit, reliable and so peace of mind for another 10 years! Very fast delivery!

Good but not great
I've just bought a 2nd one because the other one decided to chuck out false alarms at erratic times ... has until 2028 on back label . I still bought another one as it's a good product but the fact it started false alarms is a bit concerning .
