Amazon.com Product Description
Introducing the revolutionary BRK 9120 series smoke alarms which have been redesigned from the ground up. They install faster, perform better, and are even smarter than before. 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 9120B AC-powered smoke alarm with battery backup includes these features: - Ionization sensor which helps detect fast flaming fires that consume combustible materials rapidly.
- 120-volt AC inter-connectable (with maximum 18 compatible devices). The alarm can be interconnected with up to 12 other compatible smoke alarms and six compatible devices like bells, horns, repeaters and door closers. If one unit triggers an alarm, all smoke alarms in the series will sound. Power indicators show which unit in the series initiated the alarm.
- Latching alarm indicator which automatically identifies which unit initiated the alarm.
- Smart technology to reduce nuisance alarms.
- 9-volt battery backup for peace of mind during power malfunction.
- Single test/silence button which both silences a non-threatening alarm or low battery warning and allows you to test the unit's functionality.
- Perfect mount system including a gasketless base for easy installation and new mounting bracket that keeps the alarm secure over a wide rotation range to allow for perfect alignment.
- Mounting bracket lock for tamper resistance.
- Dust cover to keep unit clean during construction.
- 10-year limited warranty.
All BRK Electronics smoke alarms meet UL 217 standard and are listed with the California State Fire Marshal. They use the new UL mandated repeating 85-decibel alarm horn pattern. 10-year limited warranty. This unit is approved for sale in Oregon after new revisions on law HB2586.--Bree NorlanderWhat's in the Box
One smoke alarm, one 9-volt battery, and user's manual

 Did not come with all the parts July 23, 2010

The 9120b package does not contain everything you will need while owning this product. It DOES include everything to get you started on your path to pain. I got it installed, up and running, and chirping loudly at all hours of the night as described by previous reviewers, but when my eardrums were pierced during a particularly brutal middle-of-the-night false alarm session and began bleeding profusely, I could not find the replacement pillowcase that should come standard with this product.
I've experienced the "beep once loudly every minute for hours" thing, but I have also endured nights of 30 minute full-on false alarms when this bad-boy decides he just hasn't had enough attention in recent weeks. Usually occuring around 3:00am, my first defense is trying to cover my head with the bloody pillow for some sort of relief from the unyielding racket. This feeble attempt lasts for only a few minutes before I desperately begin searching for something to use as a ladder. The next several minutes are spent twisting, pulling, clawing, punching, and spitting at the alarm, trying to get make something other than loud beeping happen. Telekinetic attacks are futile. "No way! I ain't shuttin up!!" the alarm boldly declares. I angrily vow to find the golden hammer that will end this epic showdown once and for all, but the relentless screams of the alarm are simply too much and I am eventually defeated. I resort to taking my crimson pillow to a closet or outside where I can fashion a makeshift bed out of leaves and branches to finally get some peace and quiet (although my ears, of course, are still loudly ringing). It is usually at this point that the alarm figures it isn't damaging my brain cells at an efficient rate any longer and gives it up.
I haven't won a lot of things in my life, but feel like I deserve a medal of honor for not committing suicide after owning a BRK 9120b. Maybe another item they forgot to include in the packaging?

Replacement smoke dector/alarm worked perfectly...delivery was fast and price better than local hardwares, Lowes and Home Depot
Alarm! July 18, 2010

The BRK smoke alarms used the same wiring as the ones they replaced, so they were easy to connect. And they were easy to attach to the mounting of the former alarms. I'm very satisfied with them.
Piece of Junk July 17, 2010
S. V. Metre (Texas, USA)
Just like other reviewers this unit gives false alarms, usually in the middle of the night setting off all the other alarms in the house. For some reason the builder put this alarm in the attic and another brand throughout the rest of the house(have had not problems with the other units). Have replaced it once and problem started again after 6 months.
Save yourself time and aggravation and buy from a different manufacture. This alarm shouldn't even be on the market.
