All of these improvements help reduce nuisance alarms and save you time and money. BRK Electronics smoke alarms are designed to be easy to install, easy to maintain, and quality-engineered for years of virtually maintenance-free service.
The AC-powered BRK Hardwire Smoke Alarm includes these features:

| 8 of 8 people found the following review helpful  I should have looked closer,  Amazon Verified Purchase This review is from: BRK Brands 9120 Hardwire Smoke Alarm (Tools & Home Improvement) I ordered this to replace the 9120B with battery backup and ordered in a hurry. This model is the SAME THING without the battery backup. Since I was replacing the one in the kitchen, and the only one of that floor. I just put the 9120 in one of the bedrooms and put the old 9120B downstairs (for some reason we have 5 upstairs and only 1 downstairs). It will be alright and saved me $30. It fit fine in the 9120B slot and activated my other alarms all over the house when I tested it. 11 of 12 people found the following review helpful  False Alarms, Amazon Verified Purchase This review is from: BRK Brands 9120 Hardwire Smoke Alarm (Tools & Home Improvement) These BRK smoke alarms have issued alarms twice now, which lasted several hours each and resulted in lost work time. Initially, two of these would beep every minute and nothing I tried would stop it, so I had them replaced, and then these seemed to be OK, but almost every night we would hear a 1 second alarm. Then 2 weeks later, the alarms went off steady and nothing we tried would silence or reset them. We even had the gas company come out to check the gas applicances for CO2, since 2 of the units also had the CO2 detectors built in, but everything checked out fine, so I just started unplugging the units until the alarms stopped. A few days later, the remaining 3 alarms that I still had connected started another false alarm and eventually stopped. I don't have time to put up with issues like this, and it can result in not even believing your smoke alarms, when it may be a real fire! I only purchased these because they were plug compatible with the First Alert, but I will have...

Since the 9 volt battery is supposed to power the entire system when electricity is lost they must be replaced fairly frequently. They test at about 8.25 volts when required to be replaced. I have purchased a couple of these non-battery units to replace the ones in the cathedral ceiling that requires a ladder to replace and will invariably start chirping at 2am on a cold winters morning. I have also replace the one in our unheated attic which suffers the same fate.As long as I can get to the unit I'll stick with the battery back-ups but for those hard to reach places these electric models as a better choice. |
