Most American smoke alarms have two serious flaws: They go off while you're cooking and they're too slow at detecting a new and deadly type of fire. Good news, the new generation of smoke alarms has finally fixed these problems.
Update: June 6. Kidde just launched 9th gen alarms at the end of May. I've added them below my top recommendations.

🔥 MY BUYERS GUIDE TO PICKING THE BEST SMOKE ALARM 🔥
This in-depth guide will help you choose the best smoke alarms for your specific needs.

MY TOP SMOKE ALARM RECOMMENDATIONS: USA
Photoelectric alarms are still best. I talk about why in my guide above. Before buying, be aware of your legal requirements: search "your city" + "smoke alarm laws". I've purchased or at least through friends got hands on and extensively researched each model. Reviews for First Alert are bad because these are newly launched. Their old models have excellent ratings: amzn.to/45nw3QU
1️⃣ First Alert SMCO100V-AC || Top Pick for Hardwired Homes
Covers all the bases for modern homes and building codes requiring hardwired and interconnected smoke alarms. Check by removing your alarm, see three wire attached? It's hardwired.
This model has a photoelectric sensor + CO detector which also covers all building codes in the US. Has voice alerts telling you where the fire is.
►► amzn.to/3Vg7u3z
⁍No Carbon Monoxide Version ►► amzn.to/45i5ug0
2️⃣ First Alert SMCO500V || Wireless Protection
If your home doesn't have hardwired smoke alarms, this alarm uses wireless signals to interconnect your alarms together. All done on the smoke alarm, no phone or app is used.
If your smoke alarms are solo flyers, interconnecting them is a HUGE improvement in safety as it allows distant fires to sound the closest alarm to you. The version with carbon monoxide is cheaper (as of June 8th) than the same version without one 🤷
►► amzn.to/45i5MU8
No CO Version: amzn.to/3V6Xycs
Note some states require 10-YEAR Sealed Battery in new alarms and this alarm DOES NOT QUALIFY: AZ, KY, LA, MD, NC, OH, OR, PA, TX (Houston), VT, WI. Some states exempt wireless alarms from this rule: CA, FL, IL, IN.
If you need a 10-year battery get this:
3️⃣FIRST ALERT || Top 10-YR Battery Pick
CO + Voice alerts + Photoelectric + 10YR Battery which keeps your alarm running, no more annoying battery changes which also saves you money long term.
►► amzn.to/3KCUlNb
⁍ No CO: amzn.to/3Vg7AYZ
4️⃣ Nest Protect 2nd Edition || Smart Home Connectivity
If you're interested in smart home functionality like remote notifications for fires this is the model for you. Plus it self tests so you no longer have to push a button. Keep in mind 10-YR rules for the battery version.
Uses an advanced dual spectrum infrared photoelectric sensor and humidity detection for better false vs real alarm differentiation.
►► Hardwired: geni.us/NestProtectWired
►► AA Battery: geni.us/NestProtectBattery
⭐ KIDDE ALARMS ⭐
Kidde launched their latest 9th gen alarms end of May. These are the superior alarm for smoke detection as it has a more stringent PU foam and cooking nuisance test. My concern is their track record for reliability as they've had several recalls over the last 10 years, including their 8th gen Trusense smoke alarm lineup. Read my guide for more details.
If my friends ask for a recommendation, I point them to First Alert. I believe in the engineering and reliability of the brand.
1️⃣ KIDDE ‎30CUA10-V || For Hardwired Homes
Hardwired, CO Detector, 10-year battery, and voice alerts. You can save some money with the AA battery model but the peace of mind is worth it.

Thank you Andrew for another excellent video. I currently have both types of detectors in my home; interconnected ionization detectors and individual photoelectric CO2/smoke detectors. After watching this video, I’ll be supplementing them with at least two 8th gen UL 217 interconnected CO2/smoke alarms, one on each floor, as soon as I possible.

Many home improvement stores here in Massachusetts, where fire/smoke/CO/natural gas and propane alarm regulations are very strict, sell non-compliant detector products that fail to pass fire code inspections. Our code even requires all batteries to be 10-year rated, sealed and non-replaceable. I’m waiting any moment for the new 8th gen minimum requirements to be phased into effect immediately now that I just upgraded my entire system…for the 3rd time. This is getting expensive but still cheaper than a household of funerals and property in ruins!

@P_RO_ Месяц назад

Of the fatal house fires I learn of locally, almost all of them have no working smoke detectors with about half of those having none at all. In over half of the 'non-working' cases, it was battery powered and the resident apparently removed the battery. In many other cases the battery was dead. To alleviate the intentional disarming and problems with dead batteries, newer building codes require interconnected grid-powered units with battery back-up, yet you get the same problem as people now simply remove or unplug the units. It is paramount that safety devices of all kinds preclude false alarms or people will find a way to disable them. There is a flaw in the photoelectric or optical detectors: they will alert over airborne dust as quickly as they do smoke. Based on where their sensitivity level is set, that can be an almost imperceptible amount of dust. I hope these new detectors can discriminate against that. And here's a closing thought: Christmas may be a long way off, but for those you know who have defeated their detectors now you know the perfect present for them, and one which shows how deeply you care.

@glennac Месяц назад

Definitely a commendable thought. But unless you also offer to install it for them, it probably won’t get done. 🤷🏻‍♂️

@Lam Месяц назад

Yeah, those were a HUGE reason why people died. Hopefully with 10-year batteries and reduced false alarms that will stop being such a big problem. Optical detectors are suspectable to dust, vacuuming is recommended and almost all newer designs have dust/ bug (spiders) to reduce that issue

@Lam Месяц назад

Yeah, exactly that, it's an awareness and effort thing. Many people also think fires happen to other people which is why we have building codes and voluntary codes like UL 217

@blakem2902 Месяц назад

Do smoke alarms have a cancel button on them? Because if they don’t, it would make them way better.

@FlorenceSlugcat Месяц назад

The best way to ensure that people dont unplug them or remove the battery, is to make sure they dont trigger when there is no danger. For example, my current fire alarm is of an older type, and if I do not turn on the stove fan, it will immidiately trigger for something as little as a pancake even if the pancake is not burnt at all and i cant see the smoke. If i forget to turn on the bathroom fan, the smoke alarm in my house will also trigger from the STEAM when I shower, which imo, is worse. Imagine you are showering and it triggers the alarm in the hallway of your home and you live alone. You have no choice but to walk out of your shower. Most people who unplug or disable their alarm would do so out of annoyance from their alarm going off when there is obviously no fire. And regarding the comment above, a cancel button of the fire alarm would also be helpful. Perhaps a button to silence it for the next 5 minutes. This might encourage the people who would completely unplug or remove the battery when it gets a false alarm, to just push the button instead. While it does mean 5 minutes without fire detection, that is much better than potentially forever without it.

A few years back I had hardwired smoke alarms from the mid 1980s. I kept them because they still worked. That is, until one day I was using a staple gun on a wall that had one and the vibration must have caused something inside the smoke alarm to fail. The smoke alarm caught fire, then alerted me that it was on fire lol. I took the rest of the hardwired alarms out that day. I'm still amazed to this day that a smoke alarm can still work after 30 years, catch fire, and still alert you that it's on fire.

@cyberyogicowindler2448 Месяц назад

Was the thing mains powered or how did it start burning? (Mains lines often fail by fire before smoke reaches the alarm.) Those dread unreplaceable 10 years lithium batteries are highly flammable and certain such smoke alarms did set houses on fire (which may be triggered by even triggered by a firmware backdoor to eliminate politically unwanted people and their documents). So I solely use non-wireless photoelectric smoke alarms with harmless alkaline 9V battery.

I mean, the older-gen ionization alarms ARE extremely annoying, but they've also saved my ass quite a few times because I live with roommates and have an electric coil stove and very little counter space. Roommate throws on a pot of water for Mac-n-Cheese, turns on the back burner instead of the front, tupperware catches on fire while I'm in my room with the door (right next to the stove) shut and they're in the living room watching TV or something. This happens about every 6 months or so but the detectors ALWAYS catch it within seconds of it flashing off, we just have to remember to open the kitchen door before anyone opens the oven otherwise everyone runs around to find some kinda pokey-stick-object to turn the alarm off. Hell, it ALMOST happened with a skillet full of bacon grease on the back burner LITERALLY LAST NIGHT, I just smelled it before it caught fire cause my door was open.

The detectors hvac techs use measure from 0, because the equipment they're servicing shouldn't allow any CO into the home, and they need to know if it does. There are other things in a home that can produce small amounts of CO that aren't particularly harmful, such as gas stoves/ovens, certain types of cooking, candles, etc. If CO alarms were more sensitive, they would give false alarms that would eventually lead people to remove or disable them.

What it does do is allow sale of multi-detectors (e.g. CO2 and smoke) and dual sensor (ionization and photoelectric). Also requires alarms to support interconnect (all alarms sound together). This is not yet a requirement in Victoria but it is in some states, at least for rental properties. In Victoria smoke detectors are only required outside bedrooms between the bedroom and the rest of the house which would have been ok for non-smokers but how many people now charge phones in their bedroom overnight?

Dual sensor units have been around for decades (FIrst Alert/BRK SA301A/B/C is the one I am most familiar with), but those were basically just threshold based and almost literally two units on the same circuit board. Waveform/time is a great way to analyse, backed with all the data gathered from testing. Great to see this!

Should have quad sensor systems. Passive IR, ionization, photoelectric and CO. An RK3588S based single board computer should be in every detector. They have an integrated NPU. As far as machine learning goes, it would be a very simple undertaking by current standards. Self-driving cars is a problem that is a billion times more complex and they're working on that. The only drawback is, in order to make the system as effective as possible, you're gonna have to light a whole lot of fires to train the system. But once it is done, it is just a simple copy and paste and over the sale of billions of devices, they'll make a massive profit on the job, not to mention saving countless lives. With enough research and training, a multi point setup such as you'd find in a hospital could actually predict how the fire will progress and intelligently direct people which way to run.

Worst of all they are all connected to each other so when one goes off you get a horrible cacophony of alarm sounds!

@eaglescout1984 12 дней назад

I'm a PE that deals with commercial construction. For decades, the standard smoke detector for a fire alarm system has been photoelectric, with dual technology being a common requirement. So, if you live in a modern apartment building, you likely already benefit from that. Also, when you talk about the history of smoke alarms and mention early models that used thermometers, that's _technically_ a heat detector. And that's something we still use today. In fact, most commercial buildings have heat detectors in certain areas where it's more likely heat would build up before smoke.

@jaybee1570 Месяц назад

I bought both types of detectors for each location in my home when I moved into my house 4 years ago. All from Kidde and I have had multiple failures. Going off continuously at night for literally no reason, waking my young daughter up and traumatizing her as well as 10 year batteries that failed way early, and many false alarms. So I would not recommend going with Kidde products despite the enticing 9th gen marketing you mentioned in the description (I also think they declared bankruptcy). I will probably look at swapping out for the first alert. Really cool video!

@jaybee1570 if you're receiving replies, I had similar issues with a Kiddie waking me in the middle of the night, after less than one year of owning it - the battery was supposed to last far longer than that. I do not know which brand is best, but I can tell you that I replaced it with an X-sense that detects both smoke and carbon monoxide, and it was the best of the options available. I still think every alarm on the market has major flaws (I outlined those in a long rant in response to someone else's comment). It has been installed in the bedroom for over a year and has not had any false alarms or low battery warnings thus far. So, I suggest getting an alarm for both smoke and carbon monoxide, and can say that X-sense has not caused any problems for me.

The photoelectric ones suck in deserts that experience dust storms. As an Electrician while serving in Kuwait and Iraq -every time we had dust storms they would set the alarms off and this would shut down the central A/C on systems that were connected. It made many people upset that not only was sand and dust everywhere you’d also be sweating even more in the desert heat. They would get dusty over time also which sets them off (the LED reflects off the dust particles coating the inside). You couldn’t just blow them clean with a can of compressed air/CO2 either. Opening them up and washing the little black plastic removable cover and cleaning the detector lens with a Q- tip works but opening them at all often voids any warranty on individual devices and complete alarm systems (don’t do this, It’s better to be safe than sorry). So, we would just replace the entire detector and throw away the dirty/malfunctioning old one. I prefer a combination Universal Security Instruments 10 Year Sealed, Battery Operated, Dual Sensing 2-In-1 Kitchen Smoke and Fire Detector, Microprocessor Intelligence detector in my home with the 10 year lithium ion battery. Steamy showers still set it off though. 😂 This is not an advertisement it’s what I actually use, I ordered them from a home improvement store they are pricey but life is priceless.

Important: Use only Photoelectric type smokes alarms. Ionization have been proven way too slow to respond to fires. Details: Ionization sensors react faster to flaming fires, but only marginally (1 minute). However, photoelectric sensors detect smoldering fires (the most common type) 15 to 50 minutes faster! Note: Combination Photoelectric / Ionization detectors can be good but there is an issue. Some models require both sensors to agree (dangerous) while others will alarm when only one senses smoke. For example, I think (but have not verified) that First Alert will sound an alarm if just one sensor detects smoke. For this reason, I recommend only Photoelectric smoke detectors.

@neilbrookins8428 Месяц назад

Capt-intrepid your comment about the 15 to 50 minutes faster is misleading. Many times the ionization alarm will not sound at all. But the photoelectric alarm will sound with plenty of time to escape. How do you compare these two times? Short time vs never. Is that infinitely faster? Basically I’m saying that the 15 to 50 claim is underselling the benefits. It’s better to say it works vs the other one doesn’t work.

Good info. When I moved into this house almost 10 years ago, I changed out all of the alarms as there were 10 years old and discolored.

And when the battery voltage is below the second (lower) level, then sound the "battery low" alarm no matter if it's bright or dark in the room (This is just in case it cannot detect enough daylight and the battery level is lower and lower, then it's OK to sound the "battery low" alarm anyways, no matter if you are probably awake or not...)

I went with my grandparents, and saw basically the same sort of research shown in this video. They recommended a classical fire alarm that was physically wound up, and had a plastic/wax stopper that melted at a specific temperature. I wonder how those types of alarms perform against the modern battery of tests in a wide range of different types of fires. This was at least over 15 years ago, so I'd be interested in how those types of alarms hold up against modern testing standards.
