Alarms were promptly shipped and received. Instructions on how to set up the alarms to link the alarms could have been better. Alarms appear to work.
Charles Vaughn –
Installation is simple, setting the units to link together is very easy and they are very loud. A very good purchase to protect my family.

The BRT substitutes do not appear to be exact replacements for the SA511CN2-3ST. They dont appear to have the 3 channel capability that the SA511C has that I require for my application. Rating reflects my application apparent conflict. I will call the manufacturer to confirm channel availibility.

I recently purchased (2) First Alert ONELINK wireless, battery operated, smoke detectors for use in our motor home. I replaced an existing smoke detector in the living area and installed the second device in the storage bay on the underside of the RV. Now that I have a detector inside the storage bay, where there is a diesel furnace, 10 batteries, and lots of electrical equipment, I feel much less worried about a possible fire in that area. I’ve tested the devices and am sure that should a fire start under the coach, I will be notified by voice from the unit inside the living area . I have advised several of my RV friends to do the same. This setup should be something the RV manufacturers should consider providing when building their new offerings.
I had 2 of these exact same alarms installed at my house so I ordered more thinking it would be an easy install. No matter how many times I tried I could not get the existing and new alarms to sync up even though they were the exact same model numbers. very frustrating. Also emailed your company to ask for help but got no response. 3 starts because what I bought all synced up and worked fine without my existing alarms in the mix, but I needed them all to work together to be of any use to me.

the best choice in cost-benefit analysis.
Excellent quality, easy setup, interconnect works fine.
Fast shipping! Easy to set up! Great piece of mind that if we ever have a fire the connection between our smoke detectors will be there to alert us!

Delivery was prompt, and the smoke detectors were packed well. I think the SN511CN2 is a very real improvement for this type of smoke detector. To have voice location for smoke , battery condition , smoke detector condition is a real step up. The only thought I would suggest would be the ability to custom program the location names. Maybe not a possibility in this price range, but it would have been a definite plus in our situation.
I purchased 8 smoke detectors for my townhouse. They were easy to link and install. I’m very happy with my purchase.
They setup easily, and seem to work on the bench, but I tested with real smoke from a burning paper, (blown out), and it seemed to take awhile for the alarm to go off! I guess I have to wait for a real fire to see if they will work right! I had the smoke go right into all the vents on the detector!

I purchased the item and when It arrived I noticed that I had ordered the wrong Item But I can not return item because there is not a email or any other way to get in touch with the company to arrange for refund.

This type of system is the best I have seen with the audible voice announcement system. It makes a safe egress for all family members to know where the fire is located and how to escape , avoiding it. Great protection.
These are the smoke only 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.

Must have made several errors on ordering via Amazon, but going thru smokealert was easy and clear — and great price…..
LEE KLEIN –
Great product smoke alert was a pleasure to deal with.
Fast delivery, current inventory. Nothing but good things to say. Would buy again. Appreciated access to contractor supplies in the single pack.
Worked as described…easy to install and interconnect…one goes off and they all go off!
Will Paris –
SmokeAlert Home Fire Safety had the best addition to our First Alert in home wireless smoke alarm system. We needed 2 additional units and the 2 from SmokeAlert were the upgraded with “Voice” alarms from First Alert. Had no problem connecting to our previous generation First Alert alarms without voice. Fast delivery from SmokeAlert was a huge plus! Never had any communication with anyone from customer service because everything (ordering, shipping, installation and connecting to our system) went without a hitch. I would definitely recommend them to anyone looking for a smoke alarm system for their house.

Fast shipping, installed easy,passed my city code. Thank you
DG Junior –
Bought 4 detectors, were easy to program and interconnect, also easy to install.
Great smoke detector part of One Link System. Very happy with purchase much more security for different floors of our house.
Jennifer M –
My house was not to code for smoke detectors, and I did not want to hire an electrician to wire interconnected smoke detectors for the bedrooms. These detectors now make me feel safer knowing the bedrooms have the proper equipment.
Easy to set up and install.
I was also so excited to find this website. They had better prices than amazon AND its ran by firefighters – it just feels nice to support a business other than a big corporation. And it got to me faster than expected! Super happy all the way around
Tim B. –
Smoke detectors were just what I was looking for. Happy to support a smaller company here. They arrived promptly and I got them working quickly. Highly recommend.
Desiree First –
Some of the best customer service I have ever experienced along with great alarms. We love that they talk and all alarm together. Very easy to install. If we ever need more we will order here.
fast shipping easy to install
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!
My cousin who is a fire chief highly recommended this particular smoke alarm to us.
The alarms were easy to setup and install. I hope to never actually need to use the product but they appear to work as they should during testing.
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.
This was the best price, shipping was reasonably fast. Some work to understand linking the detectors, but the internet was much better than the included directions. Would buy again right here, anytime!
Happy Online Shopper –
Only good things to say about my purchase and delivery of my new smoke alarms. A++ Company to do business with.
Sheridan Keber –
We first installed 2 wirelessly connected units 2 years ago. Very easy to set up. We decided to add 6 more units. First… We gave successfully connected all 8 units to each other and were happy with the alerts over the entire 8 units of a individual unit location. We were a little let down that the number of programmable location descriptions has not increased or any ability to add locations. We have 2 guest bdrms AND 2 Hallways but the units only allow one location for a hallway as well as only one guest bedroom.
