Introducing the revolutionary BRK 9120 series smoke alarms which have been redesigned from the ground up. They install more rapidly, carry out superior, and are even smarter than before. All of these improvements help lower nuisance alarms and save you time and capital. BRK Electronics smoke alarms are created to be simple to install, simple to preserve, and quality-engineered for years of practically maintenance-no cost service.
The AC-powered BRK Hardwire Smoke Alarm contains these attributes:
- Ionization sensor which assists detect rapidly flaming fires that consume combustible supplies rapidly.
- 120-volt AC inter-connectable with up to 12 smoke alarms and six of a combination of UL listed BRK heat alarms and RM3 relays (maximum 18 devices). Smoke and CO alarms need to be interconnected separately per NFPA 72 and UL 217.
- Latching alarm indicator which automatically identifies which unit initiated the alarm.
- Smart technologies to decrease nuisance alarms.
- Single test/silence button which each silences a non-threatening alarm or low battery warning and permits you to test the unit's functionality.
- Fantastic mount technique such as a gasketless base for simple and easy installation and new mounting bracket that keeps the alarm secure more than a wide rotation range to let for excellent alignment.
- Mounting bracket lock for tamper resistance.

Customer Reviews
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 to rewire the plug and purchase a better quality brand.
My house came wired with about 12 of these with the battery back-up. 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.
