I don’t know what to say, it looks to be in a fully working condition. I saw a lot of comments on here stating that these come with no batteries and as soon as I unpacked mine I was like “they were right!” well.. I opened up the alarm and batteries were already inside rather than being outside of it. Check that before you get upset (like me) 🙂
Item was a replacement for carbon monoxide alarm, they were same size, easily fitted and are already working and monitoring for poisonous gasses.
Great product, came efficiently and will be useful for when we travel too
There’s no reason you should have kept the manual, or remembered what it said a year or two ago, but it clearly says your alarm isn’t broken. After replacing the batteries, you need to leave it for 5–10 minutes before it starts working again.
Does exactly what it says, not much else to say really
Everyone needs these in their home. Also if you are going away you can take one with you.
Great device, good quality and reliable, a must have item in every home
Purchased a twin set as l feel everyone needs them in their homes. Looks good, easy to wipe down and seems loud enough to detect anything unto ward. It’s all about peace of mind
Bought these 2 CO2 alarms to replace ones that had run out and never been replaced, after my annual gas-safety inspection alerted me to the fact that I should have 2 in the kitchen. Easy to place at a high level in 2 different areas of the kitchen, to be close to the gas boiler and gas cooker. Can’t vouch for battery life, as I had forgotten about the old ones for so long that they were no longer working.
Perfect bundle as needed one for every gas appliance does what it says!
Bought to replace existing alarms. They fit on the same brackets and ok for 7 years.
These are great value for two sensors. Very compact easy to use just pull The tab, and off you go!
Perfect, does exactly as I expected and a great competitive price, very pleased. Thankyou.
Direct replacement for my previous alarm. Fitted directly onto the previous screws/holes.
Gas cooker engineer recommended these. Gas was leaking causing us headaches and nausea. These will prevent and more incidents in the future. Compact, stylish and value for money. Battery and screws included
Brought these little life savers as my old ones had expired there date….they were brilliant too…..let us no we had fumes coming into house off fire…”the silent killer” Highly recommend these as they can save your life….they saved ours!!!!!!
Product was easy to install and good quality and fast drlicery
I test it on regular basis, still working, battery still ok from new. Good product.
Excellent offer – bought my mum one to! Gives peace of mind for gas products!
It appears to work as I am still here to write this review.
Out of the box pulled the red pin to activate. Screwed in the screws using the template, offered the device to the screw heads… Job done.. No bracket to fit. Batteries already installed but saved with the red pin that you remove. Top brand at a top price, well pleased
– Product very easy to use straight out of the box, instructions easy to use.
– Long battery life (had for a year and batteries still going)
– Small but sturdy, easy to find places to put the alarm.
– It is good that the alarm can be tested, (very loud when tested)
For landlords, this is a cheap but essential bit of kit.
Bought 2 of these three years ago. Were as described. One installed in our rental holiday cottage, the other in our own kitchen. Both still working as described. Fully recommended and will replace with the same when necessary.
Great little gizmo thay keeps us safe. Easy to assemble
Great battery life. Sturdy, easy to fit and easy to test.
Came quickly, easy to set up and is lasting well, happy with it.
Excellent good value easy to apply doorbell ! Very pleased with this product, and prompt delivery!
Wanted a decently priced but reliable Carbon Monoxide detector. This seems to do the job nicely and the battery lasts as long as they advertise. Easy to fit too.
Only down side to these is that there is no way to just replace the battery, so you have to dispose of the whole unit when the battery goes (which I think is something to do with how the CO detector only lasts so long, rather than a design flaw).
Very good price… luckily never gone off so don’t know how loud it is
I bought this product as we have a wood-burning stove and it was suggested to me that it was advisable to have a carbon monoxide detector. This one was reasonably priced and recommended, and it seems fine. The instructions included how to test for carbon monoxide detection but it seemed a lot of hassle and I decided not to bother. So I can’t confirm that it detects but I have no reason to doubt it and it’s a lot better than not having anything. It gives a good degree of peace of mind.
Landlord didn’t provide a Carbon Monoxide monitor so wanted one to be safe. This was on offer at the time so seemed a good option, and the battery has lasted more than 6 months now without any problem. Great to have next to the boiler in case anything happens
Basic CO detector/alarm which works on 2x AA batteries supplied. Test button and flashing LED light to show the unit is working. Excellent instructions on where to install it. Seems good value to protect my family and was recommended by our boiler tepair engineer.
Small and discreet and very loud alarm – ticks all the boxes!! Just to be aware – if buying for a rental property (in Scotland) this doesn’t meet the criteria as the batteries can be removed.
This is the 2nd purchase of this product; the first run it’s natural life and very happy to replace with a like for like.
Easy to install and test as they should. Haven’t had a leak yet so can’t comment on the alarm other than it’s loud enough under test. At this stage would buy again.
Bought these as replacements for ones I already had and although they’ve never actually sounded an alarm, the fact that they are there makes me feel safer.
Use this in a tent with a wood burning stove. It gets hung in the middle of the bell tent on the pole. Good price and essential when using stoves that could possibly kill you.
Recommended by the fire brigade to me. 10 years of hassle free protection I bought loads of these for around the house especially the kids bedrooms. Well worth the money.
A very reliable alarm. I’ve seen fireangle alarms on the market for a long time and can always trust them to keep me safe.
Place the alarm in a open area and always test them frequently!
The monitor was recommended by chimney sweep and I’m sure its great but why can’t they supply screws to hang it that aren’t so cheap they dont break when being screwed in!
Straight forward too use, I think every household should have one, after all it’s not called the “silent killer” for no reason, Carbon Monoxide can be deadly if undetected!
Very reasonable price, delivered quickly , and was very radu to install, as per instructions that came with it. A good quality carbon monoxide detecto
Seems to work ok? Pulled out the tab and that was it, it flashes away to let me know it’s still on. Thankfully never had it go off. We’ve got a new boiler fitted in the bedroom and wanted this fitted as an added reassurance that no flue gasses were coming back in the house. Otherwise we’ll be having an extra long sleep one day
Our gas man was checking safety about the house and noticed we did not have a carbon monoxide warning meter so he suggested this one which appears to be just required. Unfortunately I cannot give a result on it until we have a problem.
Small device that will fit in any place and it will not ruin you house decoration.
Easy to install, uses AA batteries and is so light that it could be stick to the wall (no need of nails, I used the 3M Velcro).
The price is also very convenient and it is a trusted brand.
…but this sort of product has an element of trust as it’s difficult to test.
We bought this based on the brand reputation and it certainly seems to be good quality, loud, and easy to use/install.
Replacement for very similar FireAngel alarm that had expired. These particular ones are supposed to be replaced in 7 years. So a small price to pay for 7 years peace of mind. Partially chose this model as it is a Best Buy recommended by Which?
We ordered this pack of 2 CO alarms but one of them came with dead batteries. Not very good!
This is the 3rd one of these that we have bought. The only thing that I would say is that the light on it that flashes is very bright, which when I have to have it in the toddlers room it isn’t good (that’s where the boiler is) however, we solved this by putting a blob of blutac over the light.
I have these in the house but I also keep one in my suitcase. You never know when you are travelling, how save the room is. Therefore I keep one in my case and its there when I unpack.
Peace of mind is everything.
Came as described. Isn’t the first one of these I have used.
Good product, does what you need it to do. Easy to install and use.
This is a replacement for previous one that stopped working.
Unsure about the overall reliability of the device as thankfully haven’t been in that situation. It loses a star because I worry it may not function when it’s needed to work. The instruction manual is a bit confusing.. Especially how it descrbies the test feature. This is the reason why I am unsure about it’s overall performance. However, I purchased fireangel smoke alarms and they’re highly regarded hence it made me want to purchase the CO2 detectors.. I will update review in the future
perched one for the boiler/utility room on the high street by us it’s 19.99 so for the price we paid
its GOOD value & as we have fore more in house & 7 they all communicate its a GOOD fire alarm
you will not sleep through all four alarms believe me
The unit is a moveable one which means no holes in the walls. I didn’t get told off by my gas safety check man, which I have been for the last 5 years. It just sits there doing it’s job. I would recommend checking it once a month all it takes is a press of a button and I must say that it makes me feel safer having it.
This product blew me out of the water! It is unbelievably good at detecting carbon monoxide, and with a bonus: it sounds an alarm if it detects it! WOW! The human race never ceases to impress me with its incredible innovation. I have rarely been so happy to receive something from amazon and I can’t wait to take this travelling with me to detect the deadly CO all around the world! I finally feel complete. I love how the light flashes as well, a great attention to detail!
I’m nervous about carbon monoxide as it’s a silent killer, so I’ve installed these alarms in most critical areas of the house. This version features two AA replaceable batteries and a test button plus LED indicators for alarm and end of life/fault indication. The audible alarm is loud and sufficient for most homes. The unit can be freestanding on a shelf or wall mounted.
In case the manufacturer reads this review there is a slight fault in the user manual which refers to approved batteries being listed on page 16 of the manual, in my manual, there is no page 16 and no list of approved batteries – this detail needs correction.
Overall, this is a really easy to use product that could save yours and others lives so well worth the small cost.
I actually kid you not. I have a home in france which needs some work doing to it. I bought a portable butane gas fire to take the chill off in the cold February evenings in one of my rooms, sadly I fell asleep only to be woken by this alarm going off at midnight. A life saver.
My log burner gave off some strange fumes in the night and the CO detector fortunately woke me…
I decided another one might be a good idea on the landing…. cant be too sure but this one is ideal and works straight out of the box…
Excellent replacement for detector which had just reached the end of its useful life. Decided to purchase one with replaceable batteries this time in place of sealed unit so that the device can come with us abroad to maintain our safety on holiday. Plus at this price I bought three devices to cover the whole house.
What can I say?! It works and might save my life one day. I live on a boat and carbon monoxide poisoning is one of the biggest reasons for boatdweller deaths. I have it next to the stove and it has a little light that flashes every minute so you know it’s doing what it’s supposed to. You can test it to check it’s still working properly which I do every so often. The instructions will tell you how to do that and you have to do it when you first get it anyway. It’s probably one of the most important things I own.
A neat little alarm from a trusted brand. The instructions are clear and even explain how to do a real world test using incense sticks rather than just relying on the ‘test’ button. Something to note is that this alarm is identical in every aspect to one sold under the ‘First Alert’ brand.
Does exactly what it says. Advised by BG engineer to have a CO detector placed near the boiler, so opted for the Fireangel due to the reputation. Not at all disappointed, the unit is compact, easy to install setup and use. Long guarantee for peace of mind, perfect.
Not more to say except it is portable.
I bought two of these for my new home as we have a large open fire in the living room, we dp not have gas fitted in the house. It works well and keeps my mind at ease. I have one by the fire and one in my room as its the next room the chimney leads too.
I got this for my Grandmothers front room, she still uses a Gas fire in that room and I’m always worrying when I see lots of orange in the Gas Fires flames,… this has allowed me to relax, I test it every month just to make sure and it works perfectly.
Stylish CO alarm with piercing sound. Fortunately not tested it for real. First one delivered did not work so contacted seller who told me to contact the manufacturer who replaced it without a problem. It should have been the seller who replaced it so not happy with them.
I recommend that everyone should purchase a Co alarm for the peace of mind to be secure
It came nicely packaged and had two batteries already fitted, with an activator strip that is pulled out to power it up. After a minute or so warming up, the green led started to flash every minute and a quick press of the test button proved that it indeed works.
Comprehensive instructions are provided including details of how to physically test the sensor with an incense stick. I shall be doing that every twelve months when I check the batteries. The instructions recommend mounting on a wall (with the fittings provided) above door height, but I’ve placed ours on a high shelf, so it should be ok.
In my view, 13 is a small price to pay for piece of mind and I would urge anyone with gas appliances to get one.
I bought this product because I’m fed up of drying washing being strewn over every door, radiator, char in the house and what fits on our clothes airer stays there for days until it dries. unfortunately it’s caused a bit of a war at home. It’s sturdy (not like what other reviews have suggested) and holds a large load of washing. The downside is that according to our smart meter, left on over night, it uses as much electricity as we use in a whole day if we’re at home! For that reason, my husband wants to get rid of it. The cover has just arrived which should make the clothes dry sooner (according to other reviews). I love it. The clothes are all tucked away in the spare room now and my daughter’s rocking horse is no longer used to hang wet jumpers with pants on it’s ears!
It looks well made and bleeps nicely when I test it. I hope I will never have the need to find out if it works. I’m sure it does.
I think it’s worth buying a well-known make when purchasing safety equipment like this. I know this is a mainstream manufacturer and have seen these as factory fitted items in new caravans.
I bought this alarm because a close childhood friend inhaled Carbon Monoxide from a faulty gas heater while they was on holiday. They survived and as you know you cannot see, smell or feel Carbon Monoxide anywhere in the air or room you are standing in. The leak can kill anyone depending on the amount people inhale into there body. I constantly check my alarm and add new batteries to it for my own safety from becoming a victim. The unit is plane white with no decoration on it, depending where you mount it in your house you might want to hide it where it is not visible. Possibly in the vicinity of your gas heater.
The audible alarm level is set at a point which should cover normal background noise levels, however if you have loud noise levels (music etc) the alarm may not be heard, but this would be infrequent.
Good product, Good quality.
Bought and installed this Alarm for our house after being made aware of the ‘hidden’ nature of Carbon Monoxide gas – a friend had died after becoming unconscious from Carbon Monoxide poisoning! The unit is easy to install & set-up and also to periodically check to ensure it will ‘alarm’ in the event of a CM leak occurring. Once installed it gives great ,peace of mind, similar to a Fire Alarm unit.
Seems to work fine when we try the test button, the green light flickers to show it’s active so can only assume it’s all good and everything is working as it should do. Apart from attempting a bit of carbon monoxide poisoning to make sure it goes off when it should I’ll have to trust the sensor is working! Similar to a fire alarm really I guess – you have to put trust in the product that the sensors are working without setting your house on fire to try it, and that the test button isn’t just making sure the bleeper is working and batteries have some life left.
All in All, nice product, looks good, LOUD beeper, not too large so you can pop it near your log burner (or whatever you think might poison you) without ruining the look too much, and certainly worth having in your home. So FIVE big ones for this.
My parents had one of their fireplaces replaced. In doing so, the contractor recommended we get carbon monoxide alarms. Seemed sound, since all the rooms are heated with fireplaces or wood burning stoves. I’d rather my parents not die prematurely, so I purchased a few of these.
Happy to report there have been no incidences. It has a self-diagnosing test, which seems fine.
The one year battery that is included, has not indicated, on any of them, that they have needed to be replaced.
arrived well in time. Neat and easy to use. As this is only the basic model I was well pleased with it although I do prefer the digital readings on the slightly dearer model this one does what it is supposed to do. Thanks Fire Angel.
Why did I buy it? Peace of mind! Small price to pay when I have 3 children in the house. Always one of those worrying things if you think you smell gas, and don’t have one of these alarms! Fire angel is a big name in these lines of products, so you can’t go wrong.
Does it work? Thankfully I haven’t had to rely on it yet, but there is a small LED that shows it’s still on, and a test button that you can test every week.
Let’s face it, every house should have one of these along with smoke alarms. Should be compulsory for rental properties!
Buying a carbon monoxide detector is never easy, knowing to pick the right one is difficult.
But fireangel have a good brand reputation and you cannot skimp purchasing a cheap brand when you and your families are at risk.
Easy to set up it tests with a loud beep – and its is loud !
I put it near my gas boiler which is very old now and thankfully hasn’t gone off yet.
I test every week by pressing the big button on the front and it does wake up the dead !
Essential purchase!
Hunted high and low for an affordable but brilliant alarm. This one I purchased after scouting around for days. It was easy-ish to install but on the other hand you needed to test it with a cigarette or scent stick which I didn’t have so i couldn’t set up until my father brought one round. However it was easy to put up and I haven’t had any problems with it 🙂
we had our new boiler installed and l invested in this because landlord used some unknown company for the service and l just dont trust him! its a bit tricky to set up l am still not sure l did it correctly but seems to be working and it is a peace of mind for whole family!
It would not pass for something super stylish by Bang and Olufsen but looks perfectly acceptable. Worth having if you have gas or solid fuel.
I have had my old fire angel product which has lasted a year over its fixed five years. This is cheaper and just takes a couple of AA batteries. My huge criticism is you need to be millimetre perfect when drilling the holes to mount it on the wall. I would a suggested add on for this be blu-tac.
Arrived promptly, I purchased in a lighting deal. I’ve always wanted to get a co2 alarm for peace of mind. On arrival, I thought how nice and compact unit it is, it comes with batteries. Apparently you should have a sealed unit fir certain building regs if that’s why you need it beware, I don’t it’s just for my peace of mind. I tested the alarm and omg that noise is sure to wake you!!! I mentioned it was Compact unit, ive put it in my living room and is not on view, but I know it’s there and it makes me feel better.
It is small and unobtrusive on the wall, looks quite smart and ‘hi tech’. I had just decorated the room and was worried it would spoil the look but its fine. If I decide to buy another, it will be this model. And it was the cheapest model I could find.
Am very pleased at this early stage.
I was very impressed with the quality of this CO detector and alarm. It is made by a reputable company and is of excellent build quality. The instuctions are clear and comprehensive and tell you the best place to mount it. I also liked the fact that the instructions explained how to test that the actual CO detector works as well as the warning siren, which gave me complete peace of mind that I can rely on this to tell me if dangerous levels of CO are ever present.
The instructions recommend that one of these is placed at least in every room that has a combustion appliance, but I have ordered another one for our upstairs landing just to be on the safe side. The fact that these are being sold for 10 more in B&Q and Wickes makes this an even better buy on here.
I’ve put this in my cloakroom which houses our boiler after our yearly maintenance company advised that we needed to have some sort of monitor to detect carbon monoxide. He was trying to flog us one for 30 but I knew that I could get a better value one elsewhere.
This is a nicely designed product, which sits on the window sill and is hardly noticeable. Does what it says, there is a light for the alarm and one for if it detects the poisonous gas. Worth getting for use in any areas where you have gas appliances.
Alarm will hopefully do what it says on the box – i.e. scream out and show a red light if carbon monoxide levels rise to a dangerous level. to ensure that the gadget is ready when needed there’s a big alarm tester button and a red light blinks if batteries run low.
Its small size is convenient so it can stand on a table, bookcase or counter within the advised distance from a potential carbon monoxide source. It’s a good buy.
Bough this product as a second unit, I also bought a Honeywell H450EN at the same time, The device has to be mounted with a screw and rawlplug, making a hole in the wall, The Honeywell unit has a small panel pin and a plastic cap, to fit it to the wall, The Honeywell unit is more expensive, but the easier to fit, It appears that you cannot change the battery in the Honeywell unit, But you can in the Fireangel . It is hard to make a choice, do yo trust the Fireangel or the Honeywell ?.The more expensive Honeywell , does seem better made, “You pays your money and makes your choice”. After all, this is to save lives !.
One star lost for hole in the wall,and the drill mess fitting it.When the unit dies, you will have a hole to fill in.
Johnny
This is the sort of device that you don’t want to know is working, if you follow me. If this detector starts bleeping I know my wallet is going to start bleeding.
It is discreet, easy to install and comes with all you need to fit it and instructions on where by to site it. Which is just as well, otherwise it would have gone in quite the wrong place.
I want to give it a full-five stars, but I don’t know if it works – I am glad to say.
Carbon monoxide is a silent, colourless, odourless killer. This is a compact detector from a well respected brand at a low price – what’s not to like?
The sensible thing is to have several (preferably from different manufacturers) and to use them at home or holiday destinations. They can go faulty and not raise an alarm, or raise false alarms – hence you should have more than one.
I have several in use and can say that (from personal experience) they do work and can also go faulty.
This CO detector is very good value.
If I have one criticism it is to do with the mode of fixing it to the ceiling. Using a paper template you mark positions for the two screws on the ceiling, drill the holes and put the screws in. The detector has two slots on the back to locate onto the two screws. Sounds easy. However if you get either of the two holes more than 1mm off target them you’ve got a problem as you can’t fix push the detector onto the screws. I bought two of these detectors. The first went up perfectly and the second didn’t! I have used CO (and smoke detectors) in the past that were better designed in this respect. Would have given the Fireangel 5 stars is not for this issue.
Purchased a week ago to replace Scottish Gas alarm, which cost twice as much and lasted 5 years until batteries gave up and cannot be replaced.
Looks the part, neat appearance with alarm test button and flashing red alarm light and green flashing active working light display.
Fireangel comes with 2 screws and rawplugs for wall mounting but as my old one only had 1 pin fitting on wall I have mounted it just sitting on its side with the 2 lights visable over the top of the wall cupboard surrounding my gas boiler, ensuring that if accidentally knocked over it will remain on the shelf and not fall into the boiler assembly!! May get round to proper mounting sometime.
When you first power up with supplied batteries in daylight you will need to sit and watch for the green light to flash momentary every minute to show that it is working! Obviously at night time you will catch the green light showing that it is in order. Good loud alarm with test button similar to a smoke alarm. Peace of mind, just keep checking for green flashing light and occasional test.
I have back boiler runing from fireplace where I’m burning coal and wood.This is only source of heating in my cottage. This Alarm will sound when my chimney gets blocked (example falen bird inside chimney). I have been lighlty poisoned by CO before and its true YOU DON’T SMELL ANY SMOKE which means BUY THIS. Smoke detector alarms only when you have smoke in house NOT CO. ALWAYS BUY BOTH SMOKE and CARBON MONOXIDE ALARM, YOU WIL NOT GET ANOTHER CHANCE IF SOMETHING WRONG HAPPENS.
I TESTED THIS ALARM and IT WORKS!!
