But do you know how long the battery life is?



Not sure how they they would know unless they owned this exact model - even then mileage will vary depending on how often it goes off and the quality of the battery used.

Incidentally, these are £4.99 or two for £8.99 at Robert Dyas with C&C (you can also collect at Ryman shops.) 10% off if you have a student discount, plus a bit of TCB/Quidco cashback. hotukdeals.com/dea…742

Fireangel and Angeleye are the same company (Sprue Safety) - the only difference is branding, Angeleye being the name they use in continental Europe.

This model did quite well in a Which? review - I like that it has a replaceable battery as every single Fireangel alarm I’ve had with a “10-year” sealed lithium battery has failed within a few years. Quite a PITA when they start pipping loudly in the middle of the night and all you can to shut them up is disable them.

The battery life is quoted numerous times. There's even a picture which shows the battery life. Assuming you're actually interested in getting a smoke alarm, I'll let you find it out yourself

You should replace any smoke alarm after 10 years. The sensors being radioactive have a limited effective time span

Had nothing but problems with the model st622 false alarming at top of staircase landing & it's always at midnight. Have exact same model at the bottom of landing that's in working order and serves just fine without any issues. Had replacement alarms from fire angel that do the same thing, Tried the whole hoover the vent thing. Believe I even swapped them the once and then the other one played up. So it must not like upstairs, I know steam from bathroom can set it off if doors left open...

Yes all should be replaced after 10 years but it isn’t because of the radioactive material. This one, and many others, has an optical sensor so doesn’t have any radioactive material in it and the ones that do use a material with hundreds of years half-life.

The electronics can move out of calibration over time, especially capacitors, and dirt will eventually layer over the sensor making it less sensitive. There is a chance the alarm will still be good after 10 years but you will never know so the industry has come up with 10 years as the optimum time to replace it.
Bought a double pack 6 months ago and well impressed with them. Very load when tested plus it’s doesn’t go off when you burn toast heat added 🔥

Yes, same applies which carbon monoxide alarms which a lot of people don't realize is as low as 7 years life.

TIL! Thanks for this, I've got 2 Fireangel alarms I put in 12 years ago, I guess it's time to get some replacements.
My local fire service came round door to door fitting these for free - they fitted 2 in my house. One failed within 2 years and the other one after 3 years. Both ran out of power - low battery signal. I'm glad they were free is all I can say. I obviously wouldn't recommend anyone buying them. Cold from me.
Bought two last year, one up stairs one down, and they both failed within a couple of months, they kept both ‘false alarming’, not great at 3am. Fireangel said it was probably dust on the sensors, I vacuumed them both as directed but still kept alarming for no reason, I couldn’t trust them after that. Fireangel did send a replacement though (different model).
Yes these had good reviews from Which? as somebody shared above so I just picked one up in the past
You want something well tested for this task because if it proves to be bad for the job, it would be too late and too costly to discover yourself.
It's not your average gadget that you'd throw away if it proves to be badly done.

Unfortunately, had similar experience. The alarms stopped working.

London Fire Brigade came round to my old dads (94 years) and put up two linked FireAngel alarms both with "10 year" batteries.
Grateful for them to come over as they also do their "fire prevention" talk to my old dad. Telling him about exits and reminding him about servicing gas appliances. Nice chaps too.

I still need to get round to reporting it to Fire Angel. I dont wont to bother the fire service with faulty alarms. But its a shame a fire alarm of all things fails and its being installed by the fire service. Its only because i pop round to my dads that i noticed it. All the care people coming round multiple times a day ignored it.

Luckily he has one of those alarm systems linked to the council and as part of the monthly fees they install a smoke and a carbon monoxide alarm.
It may help to follow the advice of the Building Regulations...
In a traditional 2/3 storey property install a heat detector in the kitchen and smoke detectors in the circulatory areas of all landings and within 4.5m of all habitable rooms.
How many of these would I need to get decent WiFi in my back garden?
Had these for a number of years. Very good. You only have to be in one house fire ( not my own home) to realise the cost is naff all compared to getting out of property in one piece.

Thank You for your effort.
Your a Star
Just make sure to avoid the smoke alarms that are 'sealed' units that say the battery lasts for 10 years etc. I had to return hundreds of these a few years back when they started sounding off after less than 8 weeks of being installed. I later learnt that the manufacturer 'FireAngel' (as listed here) had knowingly sold over 100,000 faulty units across the UK due to using built-in batteries they knew were dodgy.

I think the 10yr lithium ones are rubbish, they've all failed well before then that we have used, some in only a year or so.

Have gone back to the old school 9v ones that you replace yourself. Not had any issues so far in the 4 I replaced a good while back.
intersting to see how 2 singles is cheaper than the 2 pack lol ... bet someone still ends up buying the 2 pack
Is it worth getting these or a combination smoke and carbon monoxide detector? And can anyone recommend a decent one if these have such negative reviews... I've had a look and it seems even the sealed units don't really last long
Strange how items get so HOT on HotDeals.
This Smoke Alarm has been under £6 on Amazon for getting on for two years (bar a brief Covid spike)

Any deals for a Carbon monoxide alarm
I bought 8 these last time it come around FireAngel SB1-TP-R Smoke Alarm, 2 Pack in January

I have replaced all batteries and had 2 with the alarm going off a number of times, i.e. false positives.

I am going to replace those 2 this time and have bought rechargeable batteries for all.


They do work and I've set them off a couple of times burning croissants etc.

So 2 fails and short battery life, you get way your pay i.e. these are so cheap I'm not complaining.
“Product life span: 10 year. Warranty: 3 year.”

Surely being a safety critical device that’s meant to save lives one should consider replacing every 3 years not every 10 years. I mean, this is basically saying that the manufacturer loses confidence in the correct operation of the unit after 3 years... but just keep it hanging on the wall for another 7 and enjoy the BBQ
Not to forget inorder to confirm to BR, it has to be hardwired in with all alarms linked
Wouldn't touch fire angel alarms with a barge-pole after the experience we have had with them.
They are (were)
