Ratings may include incentivized customer reviews.
The smoke detector features dual ionization and photoelectric sensors for comprehensive smoke detection. Many customers found the product easy to install and appreciated the simple battery replacement. However, a significant number reported issues with defective alarms, false alarms, and battery life concerns. While the product's performance was satisfactory for some, the high rate of reported reliability problems suggests it may not be the most dependable option.

Make sure you test
I had to order because the store doesn't carry it on the store shelves. When I picked up at the store there were 2 duracell AA batteries loose in the shipping bag and the box inside was unsealed and had some tears. I thought.....this might be a return! When I looked at it closely at home I couldn't say if it was or not so I installed it and tested it with the button. That worked fine so I tested with smoke from a candle and even after repeated snuffings and smoke pouring around the unit it n...
Good detectors but this model is discontinued
This model detector has been discontinued so you may get one manufacturer in 2022. Two of the ones I bought were manufactured in Aug 2022 and the other 2 I bought were more recent in March 2024. I decided to keep the older ones anyway.
First Lowes would not mail this to my home when I ordered this detector. Store is 20 miles away. When picked up the box looked like a Mack truck had ran over it. The detector was manufactured in Aug. of 2022 [ two years and 3 months ago] . Have to drive to the store again to return it. I am very disappointed in Lowes
Replaced the old ionization detectors with these
Went down the smoke detector rabbit hole on YouTube and decided to update all the 12 year old ionization only detectors in my house. This dual sensor model has since been discontinued because of new smoke detector standards that rolled out this past summer, but these will be fine.
Order Pick-up Issues
Waited for some time 5-10min for someone to come to the pick-up desk for me to pick up my order. A mgr finally got someone to take care of me. Then they had to go back to Receiving to retrieve my order for a very small item (another 5 min). They have shelves & bins at "pick-up" for that purpose I thought. Not very good customer service.
Product is a great update for older detectors.
When compared to the older BRK detectors these are replacing, the batteries are much easier to change, LED is easier to see, the dual sensor is better and the wire connectors from the older detectors fit perfectly. It does have a smaller footprint than older models, so you may not be able to use the old mounting ring and some paint touch-up may be needed.
A very effective smoke alarm.
This model of smoke alarm works very well. It is hardwired to 120V and is interconnected to all of our other smoke alarms. I purchased this one to replace one that had reached end-of-life (10 years). It works great.
