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 to replace fire angel in my caravan they were reliable so replaced them with the same

This little smoke alarm packs a punch! I was immediately impressed by its compact size and how discreetly it fits into my home. The installation was a breeze, and I opted for adhesive velcro strips instead of drilling holes. One of the first things I noticed was the powerful alarm. Trust me, it's loud enough to wake even the deepest sleeper! While the battery life isn't quite a year as advertised (I've had to replace them after about 4 months), it's a small price to pay for peace of mind. Interestingly, the alarm has gone off a couple of times due to hairspray and once seemingly at random. Although these weren't fire-related incidents, it's reassuring to know that the alarm is sensitive and responsive. Overall, the FireAngel SB1-R is an affordable and reliable smoke alarm that's easy to install and blends seamlessly into any home.

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.

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.

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

Purchased for son's new home. Peace of mind. Small, so not an eyesore to look at.

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
