Tools and Hardware Reviews of BRK Brands 9120 Hardwire Smoke Alarm
Customer Review: Simple to install needs no battery.
Summary: 5 Stars
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.
Customer Review: Not quite "Plug and Play"
Summary: 3 Stars
The replacement seems to be operating just fine. The problem though, is that you can not simply put the new unit into the old units slot. I replaced all of my smoke detectors. Some required some hardware modification and others some wiring. The good news is that all of the necessary parts are there but the installation may not be as simple as you would like.
I was happy to find the product on Amazon as all of the local sources either didn't carry the product or were out of stock. The price is very fair.
Customer Review: I should have looked closer
Summary: 5 Stars
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.Customer Review: Not the model pictured
Summary: 2 Stars
The product pictured has a battery door which is the 9120B, not the 9120 as labeled (and shipped to me). This model is hard wired like the 9120B, but is missing the battery backup. Without a battery backup the smoke detector will not work in case of a power loss.
I'm not quite sure why thy make a model like this, but for me it is useless and now I have to ship back the product because Amazon did not appropriately represent the product.
Customer Review: Smoke alarm

Bought 4 of these to install in a clients home. Was having trouble finding 120vac alarms without battery back up. These were mounted quite high and would have been nearly impossible to change batterys twice a year. They worked great.
