FireAngel SB1-R Optical, Battery Powered Smoke/Detector Alarm for Home | 2-Pack, Toast Proof, Replaceable Battery Smoke Alarms for Home with Silence Button, Fire Alarm for Home

Great little battery operated smoke alarm. Looks quite discrete when mounted (I used command strips, but screws and rawplugs are provided). Based on an optical sensor not the older radiation source/alpha particle ones, but, weirdly, still have an expiration date....not sure an LED or optocoupler has a half life but what do I know!? Is this a ploy just to keep you buying new ones in the future!? Anyway, runs on two AA batteries (supplied) which is great, apparently last around 5 years but I can't validate that, they are easy to change in any case. The alarm is pretty loud too. I've found that sometimes steam from the bathroom can trigger mine in the hallway so they seem sensitive, but I think thats a good thing. For the price it's a simple fire risk mitigation to help keep your family safe, recommended!

Bought for our motorhome easy to install.

I bought these on recommendation and reviews. They are a great size at a great price and hopefully we’ll do the job. Fitted easily and up and running. Luckily not had to use them for Real so I can’t comment whether they will save peoples lives. So far so good highly recommend recommended

These are top rated for sensitivity to all types of fires by Which magazine, beating the competition, mainly Aico, even though Aico are several times the cost. The downside with FireAngel is false alarms which are widely reported. Industry people prefers Aico as they dont want hassle. My plan is to buy several extra FireAngels, and immediately bin and replace any that give a false alarm, no second chances, and by Darwinism achieve a reliable system. The included battery is useless, bin and replace with Duracell 9V MN1604.

I purchased this fire alarm in 2023, and it has been a fantastic product from day one. It came with a one-year battery guarantee, and it worked flawlessly all the way up until yesterday, when I believe the battery finally died. During the time I had it, I never experienced a single issue-the performance was excellent and incredibly reliable. The only real downside is the battery itself. It seems to be irreplaceable, which is a shame because the alarm is otherwise a quality product. If the manufacturer could move toward a greener, more sustainable design that allows for battery replacement, it would make this product both longer-lasting and more environmentally friendly. Overall, I would still recommend this alarm to anyone looking for a dependable option. If you have any questions about my experience, feel free to drop me a message, I’m happy to help.

Great products & easy to assemble with a good price tag too.

Bought to replace our date expired smoke alarm in our motorhome. A trusted brand and even though our old model is no longer made and has been superceded by 2 other models, this replacement version has the same design of backing plate so I didnt have to make new holes in the van. Well thought out design and a simple swop out. Great fit, easy replacement, should durable for 10 years.

Nice and compact, but the battery died after 6 months - hopefully that's just down to a bad battery rather than the detector itself. Time will tell...

J'ai acheté ce détecteur afin de ne pas devoir enlever le support déjà en place qui avait été collé -> nickel, il s'adapte bien au support

Perfecto.

Alarme pas assez bruyante si vous avez une grande maison pour un appartement de petite taille il suffira

Le modèle à batterie scellé se met en défaut bien avant la date de péremption. Au moins avec celui à piles on peut les changer.

Pile of dangerous rubbish
