Customer Reviews

Rated 5 out of 5 by 3 reviewers.
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
