FireAngel Mains Smoke Alarm - SW1-R Mains Powered Optical Smoke Detector with Backup Battery - Wired, Interlinked Smoke Alarms for Home with Test Button and LED Indicators - White

I’m genuinely impressed with the FireAngel SW1 R mains powered smoke alarm. The build quality is exceptional and it performs significantly well, definitely a product you can trust to keep your home safe. That said, if you’re replacing an older smoke alarm from a different brand, be aware that this model may leave some gaps around the ceiling and could require replastering to get a neat finish. You can see this clearly in my photos. For another room, I discovered that the same company offers a standalone push fit base product. It’s much easier to secure, fills gaps left by older alarms, and makes removing the smoke alarm simpler than with the standard plate. It’s worth considering this option if you want a smoother installation. All that said, the SW1 R is a great product at a good price. It’s reliable, well made, and definitely does what it promises. Just make sure you consider the points above regarding installation, ceiling gaps, and alternatives, it will save you hassle in the long run.

Good quality smoke detector. Easy to replace previously fitted hard wired system. Good make used by our local Fire service

Works as designed. Batteries included are completely dead on arrival. Your sensor will beep because the batteries are dead. Best to buy new quality batteries and do a test before connecting, the alarm should sound loud as if it is connected to power. Ordered both smoke and heat alarms, batteries dead in both.

Bought 2 to replace my old ones. Quick to install. Good price

Perfect replacement for old unit. Was priced well and delivered on time. Easy to fit and works well.
