    Rated 4.8 out of 5 by 4 reviewers.
    Rated 4 out of 5 by Best Insurance for My Older Home I bought these as 'best possible coverage' for my older #1982# home. When my home was built the local code only required two smoke detectors for a 2100 sq ft 2-story with basement. One hardwired detector in the top-most staircase/hallway on the upper floor. The second was hardwired in the hallway of the basement, just outside the furnace/utility room. I have supplemented these with battery powered detectors in the bedrooms. However, since the hardwired units were over 20+ years old, I wanted to replace them with the best -- a dual mode detector. They have been installed for ~30 days now and have performed admirably and silently for the time. This time includes repainting the basement, installing new carpet, and having the windows and skylight open to the breezes at night. Not a false peep from either one. Yes, they are 4X the cost of single mode detector; but, getting out of the house in plenty of time in case of a fire is well worth it! July 31, 2015
    Rated 5 out of 5 by Great product. Super great transaction. Much improved over prior models. No false alarms. Overall purchase and transaction was smooth and easy. April 11, 2012
    Rated 5 out of 5 by Much improved over BRK 7010B The 3120B is a huge improvement over previous BRK models. We had 10 linked BRK 7010B detectors that were just awful: many spurious alarms, silence buttons didn't work, can't tell which unit alarmed for 20 seconds at 2am then went silent, battery replacement warnings even though the units were AC powered. Our house has more than a hundred feet of alarm wiring due to modular construction, and that may be more than the 7010B electronics could deal with. We've replaced the important ones with 3120B units, and they're much better. No false alarms in a month, and the testing and silence and latching features work as documented. If the batteries stay good for more than 3 years (we never have power outages) then the 3120B will be a perfect unit. Highly recommended. October 6, 2011
    Rated 5 out of 5 by Double protection--ion/photon important This is only company selling BRK/First Alert's new ion/photon smoke detector. The double protection is strongly recommended by most fire departments. June 30, 2011
