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

 BRK Brands 9120B Hardwired Smoke Alarm with Battery April 15, 2010

I replaced 10 BRK units that were in the house when I moved here in 2001. They had been acting up and chirping frequently. While I was away on a recent business trip, all the alarms were activated at 3:00 AM. My wife was home alone, and went through amazing machinations to deactivate them. There was, gratefully, no smoke to cause the alarms to activate. So I ordered ten of these units to replace the old ones. Installation was fairly easy, and they have been quiet ever since. I like them, and feel that they were reasonably priced. They were delivered right on time, as well.

Easy to install and works perfectly. Although it is advertised as a direct replacement for an older model, it's not quite that easy - you also have to replace the mounting bracket. The electrical connection was identical, however, so no electical work was required. It interfaces properly with a network of the older models.

Had nothing but problems with the older model BRK Smoke Detector installed by the contractor who built our home. After months (years) of chirping, replacing batteries and cleaning them did nothing to stop the annoying chirping which woke us up all hours of the morning. So far, these replacement units have not let out a chirp and seem to be working fine.

Easy install..fits right over the electric box where old one was installed...this is a newer model of the old one...working fine so far...
Works OK for me September 6, 2009

I had the chirping issue with the earlier version and replaced them with this. I've had them in for a month and no issues yet. The old units were almost 10 years old anyway - i think thats about the max age.
