All units are manufactured within the past year! This Battery Operated Wireless Interconnect Combination Smoke and Carbon Monoxide Alarm with Voice Location is about the best you can get on the market. This is literally what I have in my own home. This alarm is a photoelectric smoke alarm, a Carbon Monoxide alarm, a wireless alarm and it has voice activation. With the First Alert Wireless Interconnected alarm you can connect multiple smoke and carbon monoxide alarms together wirelessly to create a strong network that will protect you and your family. The offers an exclusive, innovative voice warning system with location alert. When an alarm is sounded, the network will alert you which room caused the potential hazard so you can know where to extinguish the problem. The voice system will say directly where the problem is when the alarm sounds off.
Photoelectric detectors alarm from slow burning smoldering fires much faster than ionization alarms. This is how the majority of house fires start.
The Carbon Monoxide alarm is built in so everything is connected which is the most important thing. A smoke detector puts off about 90 Decibels and the average human wakes up from about 70 Decibels. 1 single closed door can reduce the decibel level by 20 decibels. So if you have one on the floor below you the sound is pretty much non-existent. Children and Seniors take much higher than 70 Decibels to be awoken so now you can see the problem. Now you could call an electrician out to rewire your home to put the cheaper hardwired detectors in but you are going to end up paying $1200-$1500 dollars for them to run all the wires. These alarms solve that issue and go one step furthur. These are the only alarms on the market that will tell you which smoke detector is alarming. If the alarm in your basement is going off then your master bedroom will alarm and say “Smoke in Basement”. If there is a Carbon Monoxide emergency it will actually say “Carbon Monoxide in Family Room, Carbon Monoxide level is 500 PPM(parts per million). This is incredibly important so you know where to go and where not to. I offer free phone support for the programming and placement of these alarms. I have installed first alert smoke and carbon monoxide detector in hundreds of homes so I can fill you in on some tips and tricks when you are getting them all set.

Installation and program of three First Alert smoke and carbon monoxide alarms was a snap. The units in test mode would wake up the neighbors. So far, happy with the alarms.
T –
They work as advertised
Joe –
I bought 3 of these. They installed very easily. I like that they use AA batteries instead of 9v. It’s been 1+ month and no false alarms yet. I guess the real test will be if I ever have a fire (which will hopefully never happen!).
Frank –
Bought 7 of these interconnected wireless battery operated smoke/carbon mon. for a 5 unit older apartment house.
5 installed 1 in ea. apt. and 1 in hallway and 1 in basement , programed all at 1 time together, installed all 7 , tested
and all worked wery well. For a non hardwired smoke/carbon mon. detector they save a lot of money by being wireless.
Programing was easy and the unit will tell you when the batterys need to be changed.
Chris –
I was looking around for a while for just this product and have happily used them since 2007. I have one in each bedroom at the top of the stairs in the living room at the bottom of the basement stairs in the basement AND the utility room as instructed in the manual (paper). I got the combo CO2 and smoke because the price difference just did not seem worth it not too. Expensive maybe but then so is my life and the life of my family and if it gets us out of the house in one piece and we watch the house burn down then that’s good money spent in my book. Amazingly loud especially when they all go off and knowing where the fire is “Smoke in Basement location” is awesome. They have a suggested life of 7 years and guess what… it even tells you when its time to replace them! If you are looking for a fire alarm look no further!
John Hanson –
I chose this model of alarm after much research online, but then chose the seller based on their price. Good choice, as they were not only the least expensive, but were courteous, prompt, and the units arrived in good shape! Complete with batteries, no less!

The package arrived properly packaged. Happy with my purchase.
Steve Schmidt –
Easy to install
William Ralph –
Great price and fast delivery. The system was easy to set up and well designed. It’s loud!

Works as promised,easy to program and install. Will work with other “ONELINK” alarms from First Alert.
Randall Cowan –
I’m very happy with SmokeAlert’s prices and fast delivery. I installed the 2 first alert ONELINK alarms Saturday and they work great. Talking alarms…awesome!
tim eichhorn –
I feel comfortable using the first alert products. The service from smoke alert organization turned out to be top notch. Fast shipping and sincere customer care.
I gave the high rating here because I felt the representative exceeded expectations as a result of business philosophy. Thank you Chris.
Highly Recommended!
Dana Harriman –
Very happy with my purchase.
Stephen Murphy –
Website was easy to find what I wanted, then the ordering was straight forward, and I received my order when promised. A bonus was all 12 of the alarms had 2-AA batteries included in each box! I recommended Smoke Alert to all my friends who were thinking of upgrading their smoke alarms.
Stephen Roth –
I think they are going to work great for me. I am hard of hearing, High FZ good on Low FZ. I normally don’t hear the normal smoke alarms. These seem to be a different tone plus the voice alert. My wife is going to push the test button someday when I’m sleeping from the night shift. I will know for sure then. They were easy to link.
Bryce Nesbitt –
I asked a question, and it was answered quickly and by someone who seemed to have a brain.
geoff suk –
great price, easy shopping, prompt shipping.
Anonymous –
Arrived quickly; good pricing.
Watched DVD but written instructions sufficient.
They tested fine, and communicate with each other.
Too soon to evaluate battery life.
They’ve been up for a few weeks and no nuisance alarms(CO or smoke).
I bought these w’less combo units because I needed to add CO detection on the lower level and liked the idea it would signal unit(s) upstairs. I also wanted additional smoke units so I could have one in each BR and in the LR. The combo units fit the bill and now I have lower level CO/Smoke protection that will activate units upstairs.
Jeffrey Yates –
Lowest price on internet and arrived promptly. Hopefully, will not need again, but would shop with this company in a heartbeat.
Charles Troast –
To have all smoke alarms work together is the best safe guard one could ask for. I have a very large house and thinking of one alarm going off and not hearing it was disturbing. I purchased three units (2 smoke and 1 smoke/CO) now when one goes off they all go off. They were easy to program and to have the voice tell me which one triggered the alarm is genius. I plan to add more, one in the detached garage.
AG –
Excellent product from an excellent provider.
Jeff –
I ordered four of the smoke alarms they shipped on the same day the alarms arrived the next day they are installed and work very well. Very pleased with smoke alert i will order from them again.
Anonymous –
Third time I’ve ordered from Smoke Alert. Easy ordering, quick and well-packed shipping, products as ordered, reasonably priced. What more can you expect.
gc –
extremely fast service and timely communications as it processed. the detectors are very easy to setup and well worth the investment
Eric E –
Glad to find linked alarms that are wireless. Did not want to do all the work to wire an old house. I hope we don’t have a fire for obvious reasons, but we may also end up deaf- the detectors are very LOUD! 🙂 They should easily wake us and our kids up. The location feature is pretty cool too.
Dapeng Liu –
I haven’t used this product. The seller is pretty good, fast shipping and excellent price!
Doug –
Ordering was quick and easy. Price comparison seemed good. Alarms were easy to link to one another and install. Delivery seemed like it arrived the very next day. Fast. I would definitely do business with them again.
Ken Winter –
Great products and great service. Installation was a snap. Very easy to understand instructions.
Scott Vadnais –
had a bad unit and they shipped a replacment same day.
saved me as i do foster care and had an inspection commign up.
recomended to all my other foster care givers in my last care givers meeting
Tjk –
Second time I’ve bought this same product from the same vendor. We needed to add more smoke/CO2 alarms and like the wireless feature. Fast shipping and an easy website to work with.
Also have sent friends and family members to their the Smoke Alert website for this product.
Jon J. –
I was confused by the different types and models of smoke alarms. The First Alert website offers little useful information.
I noticed a good price for the wireless, battery operated smoke and CO detectors on this website and called their phone number. My questions were answered quickly and accurately, as I double-checked through online research.
Shipping occurred within 30 minutes of my placing the order. I received my 7 detectors within 2 days.
I rarely leave reviews. My order from SmokeAlert.net was handled quickly and with excellent customer care.
The SCO500 detectors also functioned as described. I am happy with these items, although one out of the seven I ordered was received defective.
Matt –
Awesome product. Easy to install. Easy to link. Works like a champ.
Homer Rajotte –
Following a tragic fire next door, I decided to replace all the existing alarms in our duplex, which were of an unknown age.
These alarms were a bit tedious to set up at first, but I got the hang of it after the third one. Wear hearing protection when you set them up or test, because these alarms are loud!
Many thanks to SmokeAlert.net for selling these at a reasonable price. Other places online charge double, plus extra for shipping. I’ll be sure to buy here again, and I’m telling all my Facebook friends, too!
JP –
This is the second set I have purchased. I Feel much safer knowing that if one detector goes off, they all go off. No one will sleep through 7 smoke and carbon detectors. I have 2 hardwired and 5 wireless remote.
Deborah Wessner –
Excellent Service, Good Prices, Quick Delivery. Network was easy to set up and worked first time.
johnnie thomas –
very good price and fast delivery. just as advertised and easy to install
William Bridgewater –
Excellent product, excellent shipping, and excellent after-the-sale support.
W D Drover –
We followed the instructions from the package and were up and going in 20 minutes. The only problem we experienced was opening the battery tray door. It does not pull out perpendicular to the outer circumference. It pulls out at an angle as poorly shown in a small photo on the instructions. Once this was solved, all else went quickly. The units all talked to each other and were easy to test.
Thomas Tittmann –
Easy to install. Mounting bracket had extra holes allowing me to reuse ceiling holes from competitor’s alarm I was replacing.
Lloyd –
I never submit reviews but I am making an exception in this case. SmokeAlert provided me with such excellent service, well packaged and rapid shipping of my order that I felt compelled to comment on their excellent service and great prices. I am completely satisfied and will recommend SmokeAlert to my friends.
Anonymous –
The combination smoke and CO2 alarms are great. I took away one star because the date code was a little older than I would have liked. It looks like these don’t turn over as quickly as the other models. Also, the model number of the alarm didn’t match the model I ordered but I believe this is normal and is First Alert’s strange product coding.
Russell Zawoysky –
Product works as advertised.
Avon Vol Fire Fighter –
Received smoke detectors in a timely matter with a fair price. Great product with easy installation and very cool that they link wireless as I installed this for my elderly parents to give them peace of mind.
Arthur Fink –
Fine order
James Yearley –
Unable to program without assistance from tech support but product seems to be programmed correctly now and hopefully will perform when needed.
luther burdette –
Time to replace existing detectors and after reviewing various brands decision to buy First Alert SCO501CN-3ST a no brainer. Smoke Alert had the best review and pricing.
Order and shipping was handled very promptly.
Had mistake installing first unit causing damage, however, after contacting Chris a replacement unit will be shipped again very promptly.
Smoke Alert knows how to get customer satisfaction, will definitely recommend Smoke Alert to all my contacts.
Binh Do –
Product arrived quickly and works like a charm!

This system works great. I purchased 5 alarms and easily set them up for each specific location. Our home has 4 floors and we now can hear an alarm that goes off in any area of the house. We wanted to avoid the hefty fee of hard wiring all the floors or signing up for a security/fire system. This did the trick.
Charles Carter –
Easy to install, good and loud alarm, glad for the connectivity to other detectors, extremely fast service from SmokeAlert. Now that I have my house alarmed in every room, will see about my mother in law’s home.
Matthew Studer –
the web site had all i needed to know about CO, and smoke detectors, and the prices were the best online I found.
Brian –
These are very cool battery smoke alarms. Solve the problem if inter-communication in old construction.
Dawn Hummel –
These were easy to mount simple to program and works fantastically!
DOUG VELTHOUSE –
Great service, prompt delivery and a product that performs wonderfully. Thank you.
Bob –
Excellent service. Received exactly what I ordered. Arrived when it was suppose to.
Andrew Schmidt –
I purchased 2 First Alert Smoke/CO2 alarms. Price was great, delivery prompt and installation went smoothly. Hope they never go off:-).
George J. Laurer –
Price is great, service is great. Excellent experience. There should be more like him.
Michael Sawdey –
I selected this unit on the basis of Consumer Reports rating, then looked for the best price, and SmokeAlert is it. They also ship quickly and economically. The installation was very easy, even getting three units to communicate took only a couple minutes. It’s an excellent idea to use these linked units, because you’ll “get the message” even if the unit that is responding is at the far end of the house, in the basement, etc.
Dave B –
Item was exactly as described and what I needed. Good price an prompt shipping – will buy from here again.
A G Wiatrowski –
Wonderful, fast service. This is the first alarm that I have found that is truly useful for a hard of hearing person like myself. Others are inaudible to a person with upper frequency hearing loss like myself. I can hear this one and understand it even without my hearing aid. Outstanding!!!
Mark Schuster –
I purchased three Talking, Smoke & CO wireless detectors. Ordering was a piece of cake, the price was the best around and $0 shipping costs sold me on SmokeAlert. I linked them with my other First Alert wireless smoke detectors with no issues whatsoever. I know I’ll be shopping SmokeAlert for gifts for my children and their families.
Justin –
Very quick service and the best price I could find.
Neil Higgins –
great customer service,best price on web,fast shipping

Works like a champ, I have 3 set up in the house, and they all linked perfectly. Best price on line I could find.

This is my “go to” site for smoke alarm purchases. The prices are good, the shipping is quick and the quality of the products have been excellent with recent manufacture dates. They do a great job.
Adam Walsh –
Not sure what to say. I ordered a smoke/co alarm and a few days later it showed up. Easy to install and integrate with other wireless smoke alarms.
Shalom Wertsberegr –
I had some questions and they got answered fast and completely. The price of most parts was very competitive. The package arrived on time and the answers to my questions proved accurate. I hope I will never have to test the quality of the devices more than by pressing the test button.

This is a great source of smoke and Carbon Monoxide detectors. They are always very helpful, knowledgeable and willing to provide great advice. I ordered 18 sco500B units for several houses. They arrived quickly. Prices are the best I could find.
jeff smith –
The CO alarm message portion does not seem to get passed along with the smoke message to the linked alarms.
George J. Laurer –
Good price. Good company.
Brian Gregory –
I was worried how they would go together or how much time it would take. They were very easy and straightforward, highly recommend.
Orlando –
From ease of ordering to the receipt of order.
Super fast delivery. Will do business again.
JOHN FIELDS –
Integrates with my Insteon home automation system via the SmokeBridge unit so I can now get a txt alert in realtime. I had searched long and wide for the exact features of this smoke alarm, and found it wasn’t sold in the big box stores. It is available from home automation specialty sites for much higher prices. Three cheers for Smoke Alert!
Paul –
The device itself works fine. Very loud. Did not get 5 stars due to the fact that there is a limited amount of choices for the “location” that the device uses when it gives a voice alert. For instance, there is only one hallway setting. If I have an upstairs hallway, I have to call it something else and then make sure everyone in the house knows that it is something else. Also, when one alarm starts talking, it takes a while for the others to talk, so there are several devices talking loudly at the same time. Unless you clearly heard the first alarm or you are able to clearly hear the others, it might be a bit confusing. MUCH better value than the Crossfire devices.
Ronald –
Installed and tested same day I received the 3 detectors. No problem with installation and all tested OK.
Curls Magee –
I recently learned that smoke detectors have a life span of 10 years or so and realized that I needed to replace mine pronto! In searching the web for prices, I came across smokealert.net, who had the best price on the units that I wanted. The site has helpful charts that assisted me in choosing exactly what I needed, so I ordered two smoke/CO2 detectors to replace the old smoke detectors, as well as two fire extinguishers. The order arrived very quickly, and now, our house is up to date, at least in regards to fire and CO2 safety!
John Lantz –
The detectors were as described, intuitive, easy to install, and all at a reasonable price.
Anonymous –
I linked 7 of these units in my house. They all perform flawlessly when tested! Fast shipping and a great price!

Those units are very easy to configure and install.
The network Configuration between all unit is very easy, and unsing the INSTEON bridge, I have instant Email alarming.
This is a very nice system.

Simple review, all good

All work perfect will by again
Allan Rogers –
I was looking for CO alarms and found the ones I wanted here at a much better price than elsewhere.
I then accidentally ordered the wrong model, and called them and they switched them prior to shipping and the correct ones arrived promptly at my house a few days later.

Quick delivery, easy installation, good product. Had some issues with the distance of the wireless link but just put another unit between the two I had up.

Worth every dollar. Save you a lot of money by using the wireless system.

Seemed pretty easy to set up the three of them. Only took me a few minutes to get them talking to each other.

Ordering was simple and easy, pricing was excellent, and the item arrived quickly in perfect condition.
I will definitely keep SmokeAlert.net in mind for my future safety needs and will also recommend them to my friends and family.
Mike F. –
Was recommended by Chris together with SA511B. I’ve had four a couple of weeks and they seems to work great.
Jay Edwards –
Took me a few tries to get these linked and to program the locations. The alarm and voice alert are plenty loud and easy to understand. I particularly like that they notify you of which alrm has been affected and what the actual CO level is. I fully expect that they will work as well during an actual emergency as they do during test.
Greg White –
Worked great. First alert helped getting them connected
MrBlz –
Purchased to replace units that are 6 years old. These get excellent grades from Consumer Reports.
Sylvia A Lambert –
I bought this unit to replace one that I received for Christmas five or six years ago. In the meantime I had purchased two more so I have three, one on each floor. Thankfully they have not had to be put thru the test of a real event.
rey cyr –
i install wired smokey in hot attics at very hi cost and need two people to do that
now i can go faster and no attics & have a more responsive type of smokey that tell yo0u which one has the problem yea
Steve J –
The units were easily installed physically…the instructions to link them was a little vague but figured it out. Just got them installed so have not had experience with possible false alarms and testing over time to ensure they stay linked and will sense smoke during a test. I believe these are high quality units and the best smoke/CO2 linkable wireless units on the market.
Anonymous –
I’d order from them again anytime!!!
Bob H –
Very prompt delivery and the alarms worked perfectly. Will definitely buy from these folk again!
MICHAEL GATELY –
Detectors came quickly and we’re what I ordered. Installed them the same day they arrived and linked them wirelessly to the rest of my smokecdetectors.
Tom –
I was very happy with the devices that I purchased. This was not entirely a surprise after I got such good help from SmokeAlert on selecting the right device for my application. Everything was as expected and the devices were easy to set up. I like the feature that announces the location of the alarm. You have to work with First Alert’s list of location names (you don’t get to record your own) but the available choices cover just about everything you could possibly need. I’m real happy with my purchase.
Steve Hennessy –
Great service, fast delivery & easy installation. Awesome company to do business with.
Jeff Doerner –
Recieved items quickly . Detectors arrived well packaged and as advertised . Instructions provided were clear and easy to follow . Had 3 detectors up and linked within half an hour .
Alvin Bahoora –
Rare to find a photoelectric wireless interconnected unit. I will be using these in my customers’ homes from here on out.
Bruce Bobbitt –
I ordered this unit to replace one that had hit end of life. What I didn’t know until recently is these units have an end of life function and will stop working after seven years of use. They work great, I hope, since I have never had a fire or CO2 problem. My unit was shipped quickly but because of holiday shipping jams arrived a couple of days late.

The detectors I ordered are linked with voice alarm. Smoke Alert had the best prices and shipped them promptly.
Very happy with this Company.
Justin Hensel –
Thanks for shipping the product out the next day after I ordered! Product came just as described. SmokeAlart get’s 5 stars!
I unboxed multiple of these and got them set up with their locations, but the bad part is I don’t believe they are “linked” to each other. Maybe I did something wrong, but I tried quite a few times the first night and then set one off with some smoke from the fire place and the others didn’t go off even after a minute of one going off. The other bad thing is it took a lot of smoke to set it off…I used an old ionizing smoke detector that this one is supposed to replace due to the old one being over 10 years old, well the old one went off immediately and this one took about a minute of direct smoke before it went off…

Roy Stroud –
These are great. Installation was easy. They are really loud, and we feel much safer with them interconnected and both smoke and carbon monoxide. They were reasonably priced and shipment was super fast. Support from the company was good as well.
James Morgan –
Cannot say enough about this company! First ordered the wrong smoke detector. Sent back for an easy refund and ordered the correct item. Had a few questions about setup and received a call back 15 minutes after leaving a message on a Saturday and was able to get everything working that afternoon! Customer service was above and beyond. Will use this company again in the future!

Michael Gurley –
Replaced my 7 year old First Alert smoke and CO talking detectors which had reached the CO sensor end of life. The old detectors saved my family and grandchildren on a very cold morning when the rarely used gas fireplace in our living room was turned on and the intake and exhaust wall vent was partially blocked by a bird’s nest. The resulting CO alert had us out in the 20 degree cold while the house was aired. I highly recommend these great units. Smoke Alert quickly shipped these replacement units which linked with the old smoke detectors. Smoke Alert also offers the best price.
Michael M –
Name brand products at a good price with fast and free shipping. I will make future purchases from them.

Not much to comment on. I placed an order, it shipped the next day, and arrived a couple days later – everything worked fine. Linked easily to a unit I bought two years ago. Kinda boring….just set the way ordering online should be
Mimi C –
When I was searching to update my smoke detectors, I stumbled across this site while price checking. Not only were their prices significantly less than what others were charging, the reviews of the items were very clear. The detectors arrived promptly. I had a quick installation question. When I called I got a real person who knowledgeably walked me through it. I’d recommend in a heart beat.
Jonathan Lambert –
I bought 5 so I could have one in every bedroom and the kitchen and hallway. Super easy to install, set up and initiate. Took about 30 minutes total for all of them. Absolutely the best price and I looked everywhere. Totally satisfied and feel great about the protection level.
navvett@sbcglobal.net –
Very good and responsive product. However, it is difficult to understand how to make the wireless communication aspect of this product work. And, there should be a method developed which allows a testing of the unit without having to find a fire or carbon monoxide source. And, since I purchased two combo alarms, and two single alarms, not sure if all 4 will to communicate (in wireless mode) in combination.
David Stanton –
Great idea wireless interconnected alarms, easy setup. Didn’t have to get in the attic.
Megan Sills –
Very knowledgable. Able to answer all my questions to get my family the product we need to ensure our house is safe. Also, husband installed them very easily once we got the products

Easy to configure and install.
Rolland Bockbrader –
We received our order of 18 First Alert SCO501CN smoke and CO detectors quickly and in great shape. The detectors were easy to connect with each other and to install. Great product! Thank you!
Steve Z. –
WOW ! GREAT !! *****5 stars (But I’d go 6)
Felix Cook –
I purchased 3 of the First Alert SC0501CN-3ST wireless detectors in May 2016. The instructions for setting up the detectors were not clear. I called First alert technical support, and they were very helpful.The detectors are now operating, and communicating with each others.Very pleased with the product.
Mary Meyer –
I have installed my alarm (6) units. I like them cause they have the voice loud so it can be heard. Hope they don’t ever go off, but I am protected now.
Thomas Smith –
Customer support was very prompt and helpful. I highly recommend purchasing from smokealert.net.

After installing this unit with the rest of the units I feel confident that my family is safe if the alarm should ever be needed.

Easy to set up. Just follow the directions and they came with fresh batteries.
Matt Anderson –
Everything is explained very well. You know what you are buying. And very fast shipping.

We were not happy with how the smoke alarms were set up in our new house, so we decided to go with these wireless smoke detectors. I am very happy with this product and would definitely recommend them to others.

Great price, fast delivery. Very reliable merchant.
Roy Roddey –
take the units out of the box, follow the instructions (pretty easy), and you can easily link all thse units together. If one detects smoke/CO then it will sound an alert and ALL of the units will sound and let you know which unit detected the issue so you immediately know. I put 3 in a 2 story house and another in a detached garage – it linked up perfectly.
William Fetzner –
Had this OneLink product sent to another location where I could install later. Delivered much faster than expected. Price was the best too. Good company.
Keith Yarosz –
I bought two and they are exactly what I needed.
Homer Rajotte –
I bought ten of these in August 2014. Soon after, we began experiencing false trips for no apparent reason. The full alarm horn for about 20 seconds, then it would stop. During false trips, the system did not announce the alarm type or the programmed location (all ten are programmed.) These false trips would sometimes occur three times a week, then not again for several weeks.
After putting up with this for over a year, I filed a warranty claim with First Alert, and they replaced all ten units in February 2016.
All was well for a while, maybe one false trip in six months, plus one legitimate activation from burnt food, during which the system did work perfectly.
Now, we are getting false smoke trips in which the system DOES identify the alarm type and programmed location. Two different units so far within the past three weeks. I’d be interested in hearing from people who may also have this problem, especially if you’ve found a solution. (homerrajotte @ gmail.com)
Donald A Gorscak –
Purchased this to replace unit that served me well for 7 years. Wanted unit to connect wirelessly with other smoked detectors. Prices were all over the place. Price here was best by far. Even with standard delivery I received the unit in a couple days. Very pleased with transaction
TOM BARIBEAU –
Great service at a good price.
Allen Wolf –
Easy to install and set up. A lot quicker than trying to put in a hardwired system. I like the convenience of having the carbon monoxide and smoke detector in one device and the ability to hook it up to other units in the house.
Jason –
Looks like a regular smoke alarm but also checks for carbon monoxide and wirelessly connects to our others. Seems to work great. We didn’t want to wire a whole system but still wanted to be safe so that should be awesome!
Ralph –
Received as expected and installed easily… Thank you!

Bought these to replace my older detectors. I like the simplistic design of these wireless, baterry operated, ‘all in one’ detectors. These allowed me to get rid of my outlet mounted carbon monoxide detectors, freeing up my power outlets. They arrived promptly and were easy to install. I’ll replace them with the same type when they reach the end of their life.
RONALD GILL –
Good, but I wish it was dual-sensor type smoke alarm.

SmokeAlert provided the product at the best price I was able to find. Even with the free shipping, my new smoke and carbon monoxide alarms arrived quickly – within 4 days of my order.
Peter Cremer –
Replaced an old one of the same product. Great price, very fast delivery! Thanks!

Thank you for your prompt service. This unit was used to replace one of my faulty detectors. I will definitely use your company for any future needs. I will also recomend your company to frends and family.
Thanks again

I ordered the First Alert wireless smoke and Carbon Monoxide alarms with interlink. I have 3 downstairs and 3 upstairs. I love that fact when one goes off, they all go off and it tells you what room it went off in!!! This was the cheapest place to buy them by far and extremely happy I did!!!

I ordered a First Alert SCO501CN-3ST smoke and carbon monoxide alarm but I received an SCO500B. The SCO500B is not compatible with my existing SCO501CN-3ST. So now I have to replace the existing detector in order to get the detectors to communicate with each other.

My house has 120 volt hard-wired smoke alarms. The First Alert SCO501-3ST alarms function just as well. I’ve got 4 in my mother’s house and I just put 6 in my friend’s place too. Easy programming and installation. Very good range. Wonderful features! I’m sure I’ll be buying more of them later. A bit pricey? .. yes. Worth every penny .. YES. SmokeAlert.net is also great to work with. I won’t be shopping around ever again.

Thought I was buying this model but was sent SCO500B instead. I purchased 2 for $46.95 each. I found the same SCO500B at Westside Wholesale for $34.95 so I paid $24 more at smokealert.net
Wish I had found Westside wholesale sooner

Very fast delivery and all the detectors linked and worked when tested! I’m very happy with my business with SmokeAlert and their great prices!
Mel Annis –
Great service Thanks
Anthony Cutri –
The alarms were shipped to my parents and showed delivered by USPS but could not be located. I called Smoke Alert and they asked me to check with the local post office but said they would replace them if they couldn’t be located. It turned out someone had brought them inside where they were eventually found. Smoke Alert is a top notch company – thanks!

Smooth transaction and everything was straightforward.

Smoke Alert will always be my first stop to prevention and piece of mind.

this was a replacement purchase as my previous ones had reached end of like. They suite my need to cover multiple levels and most especially, alert all at once. One area of improvement would be to allow custom or have more choices of location names.

fast on time delivery. Product works well

I love these. I have used these (through various models) over the years (the Wireless Interconnect ones). I find them very easy to configure, sync with the other alarms and mount. I’ve got the fire/CO and the fire only ones and even older models purchased previously and everything just works.
John DiNicola –
works great thank you
M. Buhn –
The SCO501CN-3ST was easy to install with fast network setup linking all the other detectors. SmokeAlert price and shipping were the best I could find after searching all offers. Bravo!

Replacing a unit that started having problems. Just if out warranty but wanted to sink with existing ones. Got just what I needed at a great price. Thank you!
Charles Duckworth –
Overall service was good and product seems to be functioning, however the product received was not as pictured on the web site and I called and thought I had received the wrong product. It was explained that the product was the same but not as shown on the web site since it was mfg. at a different location.
I do think product should be the same as the web site shows to prevent this confusion, when installed works as described. Service rep. said this comes to their attn. about once per month.
Daniel MacDonald –
For all of the purchases I would not think of going to any other outlet for these items. SmokeAlert’s employees provide the best advice and expert designs to ensure I get what I need without overspending. Can’t find this kind of customer service anywhere,..
Delores Childs –
Fair price, quick FREE shipping,
Great customer service.

I wirelessly connected three SCO501CN, a CO511B, and SA521CN. The SA521CN was hard-wired to a 3120B in my furnace room. Hitting ‘test’ in the furnace room was heard throughout my house!
The OneLink worked great and the SA521CN worked as a bridge between hard-wired and wireless connections.
Edward Eldridge –
Easy to connect with other types of detectors
Carol –
Installed easily and pleased with product
Richard Schwartz –
I used cigarettes to test the alarms for smoke detection, and they work. To test for carbon monoxide detection, I did not have a suitable garage, so I placed an alrm in my truck with a garden hose from the exhaust to the passenger compartment. I started up the motor and after a while, the alarm was triggered. I was very sleepy at this point, so I turned off the car and opened the garage door. The alarm continued to sound, so I removed the batteries for a little peace, quiet, and sleep. I advise everybody to NOT do this, as it could be dangerous in the unlikely event that the alarm is faulty.
David Pasqualini –
very good product,quick service. This is my second purchase from Smoke Alert. Very happy with the quick from your company

Completely satisfied with the purchase process and product, however I never received a response to an earlier (before purchase) email question related to the product.

Shopping was easy. The unit arrived very quickly and the price at SmokeAlert was better than anywhere else. As a former volunteer firefighter, it’s a pleasure to deal with brother firefighters.

When I discovered I had mistakenly ordered wireless devices, the return process was very easy. I did have to follow up since my return was not passed directly to the department as labeled on my return, but the problem was corrected quickly. I’ve ordered more of the correct part and service has been excellent.
Tyler Rogers –
Good product. Easy to setup and have not had any hiccups as of yet.
Ordering here was easy, delivery was quick and the price was less than other retailers.

Great prices, great service, great company. Would not buy a smoke alarm anywhere else.

These are the combination smoke and CO alarms with voice that run on batteries only and connect via the OneLink wireless network so if one goes off they all go off and speak the location of the one that went off along with saying if it detected fire or CO.
I have used these for years, but this was my first purchase from SmokeAlert which I chose due to their low price. I bought about 25 alarms to cover my house, my mom’s house, my sister’s house, and my mother-in-law’s house.
They shipped quickly.
kevin pickar –
work good, really make noise when more than one is going off. too bad they dont go off in coordination together.
Home owner –
I ordered two SCO500B detectors, and received them in three days . I also had a question before I ordered so I sent an email hoping for a response. I was surprised when I received a response answering my question the same day. Good service , fast response, lowest price, all equal Great company . I will order from them in the future.

Extremely pleased with the First Alert Combination Smoke and Carbon Monoxide Alarms……..took a call into Customer Service to help us program the Voice Locations…….They were great in helping us set them up…………….Excellent Pricing….Fast Delivery….Recommend Highly
Peter Teitelman –
We recently received replacement alarms for the exact same ones we have had previoulsy as we were very pleased with the first ones. As usual, I had difficulty following the instructions for setting up the voice alarms, and so we called. I was able to talk to a technician who happened to be around and he was very helpful and patient in walking me through the steps for setting up the voice mechanisms. Our alarms are now back in place and we are all set for several more years. Thank you!
Asher Jacobs –

These five units replaced a previous set of SCO501CN-3ST units that had timed out over the seven year use limit.
The manufacturer says to program (link) the units all from one unit. IE: 1-2, 1-3, 1-4. I disagree. I suggest that you program them in series as you walk around the house for best signal reception. IE: 1-2, 2-3, 3-4.
Also, beware of internal wall wiring that will shield the signal. That is, I originally placed units on the wall above line voltage electric thermostats but the internal wiring caused me to move the units to over doorways.
Thomas Pavlock –
I had been looking for this smoke/carbon monoxide alarm for several weeks. I checked the usual places, E-Bay, Amazon and other sites. I am really glad I stumbled upon SmokeAlert. They gave me the exact product I was looking for, and at a price that I could not pass up. The total price was almost $40.00 less than I could find anywhere. I would recommend them to anyone who is interested in home/business protection items.
Sherilyn Anderson –
I ordered 2 of the First Alert SCO500B alarms. The price was better than I could find anywhere else. Received it quickly. Excellent company. Highly recommend you purchase from them!!
Gary Smith –
This is the first order with Smoke Alert, and they delivered ahead of expectations. Great experience
Kimberly Ferrell –
Awww, this company is Great to order from, my pricing was awesome cause they were on sale! First time I have been a customer here, and will definitely go here for alarms in the future. The 3 devices I purchased work perfectly, they all interconnected just fine. I did OK with them, first time I have ever used the interconnected alarms. They are battery operated and have them on every floor of the house. there is a 7yr lifetime existence. I will buy a few more in yr or so, cause I want to expand my range a little on each floor. Just can’t say enough about how easy it was to order, how quickly it all arrived, and for a 62yr old person, I was able to successfully activate them all and get them talking together. I am challenged by technology, but believe me, don’t hesitate to try these.
Jon M –
Great wireless detectors where code requires linked detectors but it’s difficult to run wires for the hardwired units. Easy ordering and units were shipped fast, received them in a few days. Price was better than mass merchandisers, what more could you ask for?
PETE BRAUTIGAM –
I have 50 years in the electrical trade, and 35 years as an electrical contractor. Over the years, installing smoke detectors in residences has been with the interconnected 120VAC detectors with battery backup. These were considered to be the best protection available in smoke and CO detectors, but had many problems that contractors, like myself had to deal with. #1 problem was the labor and materials required to wire the detectors throughout the residence. The SCO500B eliminates all of that expense. #2 the inability to silence an alarm, or to know which alarm in the house caused the alarm- the SCO500B tells you where the problem is. #3 low battery in one of the detectors. Which one of several has the low battery? The SCO500B tells you which battery is low. I have been using the SCO500B in all of the new custom homes that I am currently wiring. The only thing that I could think of as an improvement would be for more location labels for the room in a large house (especially bedrooms.)

The very next day after we installed these, my family received a talking notification that there was danger in the family room. Just so happened, my daughter forgot about the food she was cooking. Though a fire didn’t break out, the entire downstairs smelt of burnt food. We were so appreciative of the confirmation that we received in knowing these alarms work so effectively. They were easy to install and so far have been great assistance to us. I would definitely highly recommend these. I have immediate plans on buying one more.

i had bought some of these for my cousins home that was on the market. They were great for a multi story home. Bought more for mine.
just wish FA would add a 2nd floor hallway and bedrooms to the list.

One of the few wirelessly linked smoke/CO detectors on the market. First installed a set in my home to meet building code and then in relatives’ homes. Very rare to have a false alarm, easy to program once you get the first two units done. SmokeAlert ships fresh stock quickly, I am a repeat satisfied customer.
Cannons –
Family of first responders. We bought these years ago and just replaced the whole system with the exact same. They are amazing. MAN they’re loud, but they do the job. We’re heavy sleepers, especially the teens, but the fact that all devices talk to each other…the whole house knows what’s happening! Even the dog runs to the back door! Love it!
C.R. Lewis –
This device came with solid reviews and referrals. That SmokeAlert rec commended too made it a solid purchase. Very pleased. Easy to pair with my smoke only alarms I have in bedrooms. Great video from SmokeAlert team to teach you how to pair with First Alert SA511B units.
Bob A –
great item and love how it connects to other alarms in the house. the only problem i have is that the voice is not 100% clear. it would be nice to have a customized location – but i understand that.

I needed to add interconnected smoke detectors in an older home and found exactly what I needed at the best prices, in stock, and shipped immediately! Did my research and it paid off – I found smokealert.net!

I came across Smoke Alert’s website while shopping for Smoke/Carbo combos units for an older house we purchased that needed updated smoke detectors. Their price on the units I was looking for was the best I could find plus they offered FREE 2-3 day shipping. I called them before I purchased and the gentleman I spoke to was extremely helpful. He offered me advise on placement and answered all the questions I had. After the call, I was sold. The video they have posted on how to link the wireless units was great. He told me to feel free to call back if I had any issues linking the units and was help walk me through it if needed. The units I received were also less than a year old from when they were manufactured as they promised (actually they were only about 5 months old).
I would recommend them to anybody I know and would definitely purchase from them again.
Thanks Smoke Alert Team! Keep up the good work!

I received 2 First Alert smoke/carbon monoxide detectors that were exactly what I would have got from a retail store but $10 less a piece. Arrived in a rather short time considering the covid delay. Great place to purchase safety items for your household.
W. Hoffman –
I had replaced half of our smoke/CO alarms a year ago with this model. This year I replaced four more. Easy to program and install. I feel our house is safer with these installed on all floors including four bedrooms.
Shirley Fey –
Happy with this alarm . Second one I bought.

I have two of these already in my house. The last detector we had left did not have interconnectivity, so when it finally needed to be changed, I made sure to get the updated version to replace it. Connecting them with the other two existing detectors was easy. Hopefully these last just as long.
KEC –
SmokeAlert.net is top notch. Good product, best price and fast shipping. What else could you ask for? Installed 3 of the SCO500B units and 3 of the SA511N2-3ST units. They all interconnect with each other. Instructions from First Alert for setup are a bit unclear, but not too difficult to figure out. I’m so glad that I found Smoke Alert.net online and would absolutely buy again from these folks.
