Smart optical smoke alarm for batteries and mains Smoke alarm Battery/Mains

The verdict is in: this is the best smoke alarm that money can buy

The Nest Protect 2nd Generation Smoke + Carbon Monoxide Alarm is a smart smoke alarm that combines the functions of a smoke alarm and a carbon monoxide alarm into a single device, providing protection against both smoke and CO. It was first introduced in 2017, and it emits alarms in the same manner that a conventional smoke detector would, in addition to sending alerts to your smartphone. Because it does not come with a function for detecting heat, it will no longer be suitable for use in homes in Scotland after the year 2022. However, how accurately does it detect smoke, and how quickly does it sound the alarm? We put it to the test to find out, so keep reading for our comprehensive analysis.

Pros
Exceptionally rapid in all smoke tests to produce a sound
Notifications are dispatched to your mobile device.
A Best Buy that also functions as a carbon monoxide alarm.
Only the cost remains.
This is an alarm that truly sets the bar very high. This smoke and carbon monoxide alarm from Nest is one of the few products that have won both the Best Buy and Best Product awards more than once. As a smoke alarm, it sounded quickly in all four of our practise fires, and it was the smoke alarm that sounded the quickest in three of the fires.
It was twice as quick as the slowest alarms we’ve seen when dealing with smoke caused by a flaming fire that involved a solvent-based substance. And it was able to detect smoke from burning cotton more than three times faster than the alarm that was the least responsive during the test. When it detects smoke, it will also send an alert to your smartphone. To link the two together, all you need to do is download the free Nest app on your mobile device. This Nest alarm is also a really good carbon monoxide detector. In fact, it was one of the best carbon monoxide alarms that we tested, so we included it on our list of Best Buys.
Even though this Nest alarm is several years old at this point, you shouldn’t be concerned about using it because it is still among the very best products that we’ve evaluated. However, given that it is not a heat detector and cannot be connected to one, it will no longer be appropriate for use in homes in Scotland after February 2022, when the law is scheduled to be updated.

Ionisation smoke alarm

Compare verdict: An excellent smoke alarm

The mains-powered ionisation smoke alarm from Ei Electronics, model number EI141RC, has a lifespan of ten years by design. Because it has a back-up power supply in the form of a standard 9-volt battery, it will continue to function even if the power goes out. An electric current is generated inside the alarm, which allows it to detect the presence of smoke and triggers the sounding of the alarm when smoke is detected. According to the instructions provided by the manufacturer, an alarm of this kind works very well in a bedroom setting. You can link the EI141RC with other connected EI alarms in your home by purchasing the Ei168RC RadioLink base. This will allow all of the connected EI alarms to sound when any one of them goes off. Because of this, it will be acceptable under the new legislation that will take effect in Scotland in 2022. But how effective is it when it comes to sounding the alarm when there is smoke in the air? To find out, we put it through some tests. Continue reading for our comprehensive analysis.

Pros

In all of the smoke tests that we put it through, it sounded quickly.
The volume is not an issue at all.

Cons

None was located throughout any of our investigations.
It performed extremely well in our tests at detecting smoke and sounding the alarm, which is why we are pleased to recommend it as a Best Buy product. This smoke alarm is excellent and we highly recommend it. When the law in Scotland is changed in 2022, it will also be suitable for use in homes there. Both of the alarm samples that we tested did an excellent job of sounding quickly when they were programmed to detect smoke from fires involving plastics that burned quickly. The same thing can be said about its lightning-fast responses when it was given the task of sniffing out smoke from our liquid solvents fires, where it was extremely quick to sound off. In addition to this, it was able to quickly detect smoke coming from test fires made of both cotton and wood. In our tests of the sound output, it had no trouble reaching the necessary volume level.

Smoke alarm
Only the mains
Ionisation smoke alarm

The conclusion is: this is an excellent smoke alarm

The Kidde Firex KF10 is a smoke detector that is powered by the mains and has a 9V alkaline back-up battery that can be replaced. It makes use of an ionisation type smoke sensor, which the manufacturer claims is best suited for locations where there is a risk of fires that can spread rapidly. It is not possible to remove it without the proper instruments because it is secured with a locking mechanism that is resistant to tampering. Homes in Scotland, which are required to have smoke alarms that can link to other alarms in the home beginning in February 2022, are good candidates for the KF10 smoke alarm. It is possible to hardwire it to 23 other compatible mains-powered alarms, such as the Kidde KF30 heat alarm, in order to create an interconnected system. This means that if one alarm goes off, it will also set off all of the other alarms in the system.

The warranty on the alarm is good for six years. But how reliable is it in terms of sounding the alarm when it’s required? To find out, we put it through some tests. Continue reading for our comprehensive analysis.
Pros
Rapid in the detection of burning plastic and solvents
Conveniently loud enough Negatives
Inability to respond as rapidly to fires involving cotton or wood
This smoke alarm scored highly in our evaluations, and we recommend purchasing it. It responded rapidly to smoke caused by the combustion of plastic and solvents, and it performed adequately when detecting the combustion of cotton or wood. It reached a peak of 90 decibels, which is considerably louder than necessary. In addition, when connected to the Kidde KF30 heat alarm, both alarms went off at the appropriate times.

Battery only for the smoke alarm

The verdict is that it is both inexpensive and quick to sound.

Because the battery is hermetically sealed inside the smoke alarm, the FireAngel ST-622 10 Year Thermoptek Smoke Alarm has a lifespan of ten years. Because of this, you will never need to replace the alarm’s batteries. However, because it cannot be connected to other smoke and heat alarms, it will no longer be suitable for use in homes in Scotland once the law regarding their installation is updated in 2022. In spite of the fact that it does not break the bank, one must ask: how well does it detect smoke? You can read on for the results of our tests that we conducted in 2017, so get ready.

Pros
All of our practise rounds revealed a rapid rate of sound.
Excellent value
Cons
None
When tested with smoke from each of our test fires, the Best Buy smoke alarm from FireAngel did a good job of quickly sounding the alarm. However, because it cannot be connected to other smoke and heat alarms, it will no longer be suitable for use in homes in Scotland once the law regarding their installation is updated in 2022.
It was the third fastest to respond when it was tasked with detecting smoke from a smouldering wood fire, and it was the runner-up when it was tasked with dealing with smouldering cotton smoke. In addition, it features a battery that is hermetically sealed for ten years and represents an excellent value. Don’t worry about it being “long in the tooth” because it’s not worth your time to worry about it at all. Despite the fact that it was manufactured in 2017, it is still among the most effective smoke alarms that we have examined.

When compared, the verdict is clear: a reliable smoke alarm

The mains-powered smoke alarm from Aico, model number Ei3016, has a lifespan of ten years by design. Because it is equipped with a built-in rechargeable lithium battery that doubles as a backup power supply, it will continue to function even if the power goes out. It does so by employing an optical sensor, which, according to the manufacturer, is ideal for identifying fires that are only just beginning to smoulder in the home. If you purchase the additional Ei3000MRF wireless module, you will be able to link the Ei3016 with other connected EI alarms in your home, such as the Aico EI3014 heat alarm, so that when one alarm goes off, it will cause the others to go off as well. When the law regarding smoke alarms in homes in Scotland is updated in February of 2022, this alarm will be suitable for use in those homes. But how effective is it when it comes to sounding the alarm when there is smoke in the air? To find out, we put it through some tests. For our final thoughts, be sure to read the full review.

Pros It can quickly detect smoke coming from burning wood or plastic.
Conveniently loud enough Negatives
When responding to cotton or solvent fires, not as quick as the best in the industry.
This smoke alarm performed well in our tests, and it is not too far behind our Best Buys in terms of its overall ranking. We were pleased with how quickly it detected smoke and activated the alarm; however, we have seen a few other models that are even quicker. The Aico Ei3016 was quick to detect smoke from burning wood and plastic, but it was not as quick to detect smoke from burning cotton or solvents. However, when tested together with the Aico EI3014 heat alarm, both alarms sounded at the appropriate times during the test. According to the results of our listening tests, the volume was easily high enough for everyone to hear it.

The consensus is that this smoke alarm is pretty reliable.

A hermetically sealed and tamper-proof battery is included with the purchase of the FireAngel ST-750 10-year Thermoptek smoke alarm. This battery will provide you with smoke detection for a full decade. According to FireAngel, the ST-750’s thermally enhanced optical sensor gives it the ability to detect fires in a relatively short amount of time. We put this hypothesis to the test by conducting experiments on it in our laboratory. Check out our conclusion, the results of our fire tests, and the overall test score for this FireAngel smoke alarm to determine whether or not you should put it on your short list of potential purchases or put it back on the shelf.

Pros Didn’t do too poorly in any of the smoke tests

The optical or photo-electric sensors in the FireAngel SB1-R smoke alarm detect large particles of smoke and trigger the alarm when they do so. The alarm is powered by a battery. This indicates that it is suitable for use in areas such as corridors, bedrooms, and living rooms. When the regulations regarding alarms in Scotland are updated in 2022, it will no longer be suitable for use in homes there because it cannot be connected to other alarms. The manufacturer tells us that it is designed to reliably detect smoke for up to 10 years, that you will need to replace the 9V battery every 12 months, and that they provide a warranty that lasts for three years on the product. However, how well does this FireAngel smoke alarm detect smoke, and how loud of an alarm does it sound when it detects a fire? To find out, we put it through some tests. Continue reading for our in-depth analysis and the results of our tests.

Pros\sAffordable
Quick to make a noise
Tolerably loud.
Cons
We’ve experienced alarms that are more rapid all the way around.
This smoke alarm passed most of our tests with flying colours and is on the cusp of earning a spot on our Best Buy list. But because it can’t be connected to any other alarms, it won’t be suitable for homes in Scotland when the law there changes in 2022. This will take place. In general, we were satisfied with how quickly it detected smoke and sounded the alarm; however, we have seen a few other alarms that are quicker off the mark, and as a result, we are unable to include this FireAngel in our lineup of Best Buy products.

Although it was quick to react to smoke from burning cotton and did a good job of detecting smoke from quickly igniting plastics, we have seen alarms that have reacted to smoke from fires more quickly. When the alarm was activated in the presence of smoke from both wood and solvent fires, it wasn’t too bad of a situation. According to the results of our listening tests, the volume was easily high enough for everyone to hear it.

Identifying characteristics

Smoke alarm
Ionization smoke alarm that operates only on batteries.

Contrast the verdict, which is inconsistent.

The Kidde i9080 smoke alarm comes with a ‘hush’ feature that temporarily mutes the alarm for ten minutes if it is accidentally set off. This feature also comes equipped with an escape light that illuminates your path out of a smoke-filled room. Because it uses batteries that can be replaced and does not communicate with other alarms, it will not be suitable for use in homes in Scotland once the alarms law is updated in 2022. The most important question is, in the event that there is a real fire, how quickly and how loudly does this smoke alarm respond? We put it through its paces by using it to fight four distinct kinds of fire in order to determine how quickly it activates, how loudly it alarms, and how bright the escape light actually is. Continue reading to learn our conclusion, the outcomes of our fire tests, and the overall score this Kidde smoke alarm received in our evaluation.

Advantages It can be used to put out fires caused by fast-flaming plastics and solvents
Cons: Not particularly loud, but easily audible Pros:
Our test fire was conducted with wood and was slow to sound.
A sluggish response when attempting to detect smoke from our cotton test fire

Smoke alarm

The verdict is the same: it’s a reasonable smoke alarm

You can enable text alerts or test the system using your smartphone or another portable device if you have a Fireangel Pro FP1640W2-R, which is a smoke alarm that is powered by mains electricity. It also has wi-fi connectivity, which enables it to link wirelessly to other devices in the vicinity, such as the FireAngel Pro FP1740W2-R heat alarm, in order to create a network that is interconnected. Because of this, once the smoke alarm law in Scotland is changed in February 2022, it will be appropriate for use in homes there because all of the alarms will go off at the same time if a fire is discovered in any part of your home. Even if the power goes out, it will continue to function thanks to an internal lithium battery that has a lifespan of ten years and serves as a backup power supply for the device. It comes with a guarantee that is good for five years. But how effective is it when it comes to sounding the alarm when there is smoke in the air? To find out, we put it through some tests. Continue reading for our comprehensive analysis.

Pros It can detect smoke from burning wood very quickly.
Loud alarm Cons
When it comes to fighting fires caused by plastic, cotton, or solvents, you are not as quick as the best.
Although it performed well in our tests, this smoke alarm is not quite good enough to be considered a Best Buy. Overall, we were satisfied with how well it detected smoke; however, we have seen models that react more quickly than this one. It was quick to detect the smoke coming from burning wood, but it was not as quick to detect the smoke coming from burning cotton, plastic, or solvents. However, when it goes off, the alarm can be heard clearly and loudly, and when tested in conjunction with the FireAngel Pro FP1740W2-R heat alarm, both devices responded quickly enough to the potential threat.

The smoke and carbon monoxide can both be detected by the Kidde 10SCO alarm. It comes with a 10-year warranty and has a replaceable 9V battery that can be accessed easily through a hatch in the front of the alarm. This alarm also has a convenient access hatch. Because it is unable to be connected to any of the other alarms in the house, the new legislation that goes into effect in February 2022 will render it unsuitable for use in Scottish homes.

The smoke alarm from Ei Electronics, model Ei100B, is offered at a price that won’t break the bank and is accompanied by a warranty that’s good for five years. However, this model does not include an escape light, so it won’t be suitable for use in homes in Scotland once the legislation regarding smoke alarms is updated in 2022.

The verdict is comparable: satisfactory, but not better.

The diameter of the Cavius 2001-033 smoke alarm is just 4 centimetres, but despite its small size, it is designed to perform the same functions as larger alarms. It is powered by a CR2 battery that can be replaced, which is the kind of battery that you might use in a camera, and it makes use of photo-electric sensors to alert you to the presence of smoke in your home.

 

Because it is unable to be connected to any other alarms, it will no longer be suitable for use in homes in Scotland once the new law takes effect in February 2022. Because of the method it employs to detect smoke, the optimal location for it would be either the bedroom, the living room, the hallway, or the landing. It comes with a warranty that is good for two years.

But how well does this little smoke alarm work when it comes to detecting smoke? To find out, we put it through some tests. Continue reading to learn more about our conclusion and the outcomes of our fire tests conducted on this Cavius battery-powered smoke alarm.
Pros
When a plastics fire is detected, the ability to quickly detect it and sound the alarm is a distinct advantage.
Loud enough.
Cons
In our tests with wood, cotton, and solvents, we observed alarms that sounded more quickly than usual.
There have been many alarms that sounded more slowly than this Cavius model, but there have also been many alarms that have sounded more quickly. As a result of this, this smoke alarm has a long way to go before it can join the ranks of our Best Buy smoke alarms, and it won’t be appropriate for use in homes in Scotland once the law regarding smoke alarms is updated in 2022.

Its response times were, on the whole, pretty inconsistent. During our tests with flaming plastics, it detected smoke more quickly than the majority of alarms, but during our other smoke-detection tests, it wasn’t particularly quick. However, it went off in all eight of our tests, and the volume was sufficient for us to be able to hear it, so we can say that this alarm is satisfactory on the whole.

Pros
Quick to sound the alarm upon detecting smoke from a fire involving plastics.

Cons
During our simulations of wood and cotton fires, we tested alarms that sounded more quickly than others.
Because we have tested other alarms that responded more quickly in most fire scenarios, we are unable to recommend the FireAngel alarm as a Best Buy despite the fact that it is not a particularly poor smoke alarm. During our tests, we discovered that in comparison to other alarms, it detected smoke faster when reacting to our fast-flaming plastics test. This was one of the findings. And it wasn’t sluggish when detecting smoke in the flammability test we ran with solvents. On the other hand, when it was set to detect smoke from a cottons fire, it worked a little bit faster than when it was working to sniff out smoke from wood that was burned slowly. However, when it did sound the alarm, it did so at a volume that was easily sufficient.

When we tested it with flaming cotton and various solvents, however, its response time was extremely sluggish. The positive aspect is that the alarm is very audible when it goes off. And when tested together with the FireAngel Pro HT-230 heat alarm, both products were able to sound the alarm in a timely manner when tested together. ‘Thermoptek technology,’ which combines optical sensing with thermal enhancement, is said to be used in the ered smoke alarm, and this is intended to speed up the alarm’s reaction time.
