Newer product on the Market! Great option for hard to reach units and for apartment complexes or rentals. Once the unit is up it should be good to go for 10 YEARS! You should still test the unit by the manufacturers recommendation. The BRK SC9120LBL alarm features a dual ionization smoke sensing chamber and an electrochemical carbon monoxide sensor, an 85dB horn and a “silence” feature. This alarm features a 10 year battery backup. The battery drawer is shipped pre-locked so battery will not be discarded prematurely. Under normal conditions you should not have to replace the battery for the life of the alarm.
“Intelligent Sensing Technology” system is designed to reduce nuisance alarms.
“Latching Alarm Indication” remembers which unit initiated an alarm. When interconnected in a series, the unit that triggered the alarm rapidly flashes its red LED indicator. After the alarm condition subsides, the initiating unit will store in memory or “latch” the information and begin to flash the LED indicator 2 seconds on, 2 seconds off. The “Perfect Mount” system features a gasketless base and a mounting bracket that keeps the alarm secure over a wide rotation range to allow for true alignment.

Battery installation and removal can occur while the unit is mounted to the ceiling or wall via the side load battery compartment. Two locking features are provided to prevent battery theft and/or theft of the unit. Connection to AC power is made with a “Quick-Connect” wiring harness. Installation is quick, easy and cost effective.

Good price, quick service
Laurie Kraynick –
Smoke/O2 detectors were almost $20 cheaper than sourcing locally, SUPER FAST shipping, will be doing business with this company again and again.

What else to add;)?
Terry Crane –
Found the smoke detector on the cheaper than in the store with free shipping. It came quickly. Very happy.
John Mattaliano –
Great price, fast shipping. I replaced my 8 yr old BRK’s. Interchangable with the existing install ring. Install took less than 1 minute each.
Paul CLINCH –
quick delivery. products just as advertised

Very good delivered price on 5 of these all with 2016 dating. Replaced malfunctioning First Alert models using standard AA and 9 volt alkaline batteries. Old units were dated 2007 and installed in 2008.
Very fast 2 day delivery.
Love the promised 10 year battery life – I have one of these over a king bed where I have to use plywood on the bed to hold a ladder to change batteries every year!
Easy to reuse old mounts except one I had to update using the new one supplied. No rewiring needed on my 3 wire system and First Alert brand.
Loud enough and easy to test – like these a LOT better than the ones that have the annoying verbal warning, especially when the alarm is false as is almost always the case.
Tracy Singer –
These new combination CO2/smoke detectors are fantastic and for only $8 more per unit with a 10 year battery? It’s not a question. Twice the life span and no annual battery swaps will save me money over the next 10 years.
Stop buying 9V batteries and climbing the ladder several times a year. If you currently have the SC9120B, these will connect to the existing system and are going to be maintenance free for their life span.

I needed to replace nine BRK 9120B smoke detectors. The SC9120LBL detectors were a great choice. I was able to use the existing mounts and wiring harnesses, so it took me as long to replace the entire detector as it used to take me to replace the 9-volt battery in the old detectors. Plus, now I have the CO detection and don’t have to worry about replacing any batteries. The price from SmokeAlert.com was unbeatable, and the detectors arrived quickly and as advertised.

Completely satisfied. I had called to ask for some info on different smoke/co detectors. Chris was very knowledgeable and helpful. I ordered 9 units and it was at my doorstep in 3 days. I’m usually an Amazon customer but I highly recommend SmokeAlert!
Osvaldo Morales –
I was having same issues as many homeowners with beeping alarms throughout my house. I have 12 smoke alarms to deal with and finding the beeping culprit in the middle of the night was insane. I decided one night in early October that I had to find better alarms than the 9-volt battery type. I found these units. Installation was simple. About 5 mins per alarm.
Similar to a bad toothache, my relief was immediate and profound.
John D’Amaro –
Item was exactly what I ordered.. No problems
Joe Schmuckatelli –
Bought to replace 10 year old detectors. Direct replacement. Ten years without annual battery replacement is a great improvement. Easy peasy.
Sherrie/Doug Matthews –
Very helpful in helping us determine what to get to replace our current smoke detectors that were old and not working. thank you!
Tim Rittal –
Got 8 of these a few months ago but I was out of town. Just installed & it was very simple since they replace another BRK alarm which had 9 v batteries. Very good price. Best I could find. Time will tell if the ten year batteries live up to the claim. I have 23′ high ceiling in LR & changing batteries a pain.
Richard Percaccio –
Called with questions and they were nice. Their price was better than Amazon. I received my units quickly.

Like the idea of 10 year life span. Reasonable price. Shipped and received in a timely manner. Install was quick and easy.

Excellent replacement for older model. Fast delivery as expected. And they were easy to mount.
Tom Kusleika –
SmokeAlert has done everything possible to deliver a great product at a great price. Their website does a good job to help you select which detector to purchase – in my case the replacement detectors included CO detection, a feature the old detectors did not have. My order arrived promptly via USPS mail and I had the detectors mounted the same day. The old detectors should have been replaced in 2005! Thanks!
Chris Webster –
I am grateful that there was no design change to the interface, these were plug and play with the units that were installed 12 years ago. I easily disconnected the old ones and plugged these in.
Gary S –
Quick response by email and they shipped out the product very fast. I bought the 10 year First Alert that automatically start beeping when the 10 years expire so you need to make sure the company that you buy from has current inventory. Smoke Alert has current products and the code date was like 45 days from when they were manufactured. I would give them a A ++ for service, price and freshness of products!

This is the second time I order from here and it is easy. The price is great and shipping is fast.
Michael Maracz –
Per Fire Dept I need (4) Smoke and Carbon Monoxide alarm instead of the (1) I ordered.
The same number of alarms for Linda Granath at 4193 Lanier Ridge Walk.
We both need to order (3) each of the Smoke and Carbon Monoxide Alarms.

Replaced old BRK smoke and CO detectors with new 10 year sealed battery units. Easy replacement; just loosened 2 screws on old mounting ring and replaced with new ring. New detectors plugged into existing connection.

I bought these to replace the original BRK detectors in my house (~15 years old), which were starting to give false alarms. SmokeAlert had unbeatable pricing, shipped within a few hours of order, and the manufacturing dates were all within 2 months of purchase…I couldn’t be more pleased.
Jean Aubel –
Very satisfied with service and product
Recommended you to our agency for their other buildings needs.
Larry Schick –
It arrived very quickly and I installed it easily. The paperwork was totally sufficient for a single device, but the multiple device set up seemed just as easy to set up.
Jennifer Coombs –
Great Company, Terrific Service, Fast Shipping.
I will need to wait to fully review the item as It should have a 10 year life span. the last unit we got was supposed to be 7 and started having failures around the building after 3-5 with malfunction codes. Hopefully the updated product is better.
A Brown –
Easy to install, purchased two and they work in unison when wired with red wire; suggestion remove the plastic battery protection first. Its a pain to remove probably the hardest part of the installation. Does it work? Hope I’ll never find out.
Chris –
Good products. Good pricing. Quick shipper. I will purchase from them again.
Robert Kufta –
arrived on time with no problems. Thanks

I own several rental properties in the Augusta area so this was the fourth time I purchased products from Smoke Alert. As usual, their prices are significantly lower than local home improvement stores, the order processing works well, and the products show up as promised. Great company to do business with and I highly recommend!

I ordered alarms for Smoke, CO2, alarms that will all go off when one registers a problem and WIFI alarm with voice. The alarm in your catalog said it did . everything. I ordered them (4) . My electrician and I double checked what I requested and we checked the box and compared the part numbers and they matched but, it did have the voice and didn’t have the capablity to set alll alarms at once.

Very good price and easy install as a replacement for older First Alert Alarm.
Safe and Happy –
The alarms shipped quickly, included clear instructions, and were easy to install. All are working, and I don’t have to climb a ladder to change the battery every year! I wish they would make a 3-way combination – Ionization and photoelectric smoke, and carbon monoxide. I had to buy a few of these and a few of the photoelectric to get all types of detection.

I bought these because smokealert had a great price and shipping!! Also, they have a 10 year battery which is cheaper than replacing the battery every year!
Thanks Smokealert!
