Summary: Another voice in the chorus
Comment: I have the misfortune of having recently moved into a new home with one of these smoke detectors. I agree with many of the reviewers here, and am writing this review just to add my voice to the chorus. Attention potential buyers: This thing is far worse than useless. Random intermittent ear-piercing bleeps, unintelligible documentation, shoddy worksmanship ... it's making my life a living hell. I replaced the battery and cleaned the unit with compressed air a month or so ago and it was quiet for a bit, and now it's starting to go off in the middle of the night (and at other random times) again; worse, since all the smoke detectors are interconnected, when this one goes off they all go off.
It's a horrible piece of junk. Steer clear.

Summary: RIP-OFF!!!!!!
Comment: This product is TERRIBLE! We have a combination of 4120Bs and 9120Bs and they have gone off intermittently ever since our electricians installed these. A lot of the time, these go off during the middle of the night, probably due to power fluctuations--but I agree with the poster who questioned "Why have a battery backup?" if the thing won't work. There are undoubtably going to be fluctuations of the power grid; but when these go off for that reason, in my mind is reflective of poor design. Replacing the battery is a challenge worthy of a the most expert puzzle solver. My advice -- look for another brand, or buy earplugs.

Summary: Replacement Smoke Detector
Comment: I bought this item to replace the older/outdated smoke alarms. What I like most was it plugged right into the current connector. No wires to splice. The old plate had to be replaced, but that was loosening two screws taking the old one off and putting the new one in. In all, it took me 5 minutes to swap the old with the new. If you have a BRK brand alarm, I'd strongly recommend this as a replacement.

Summary: Warning!
Comment: Please read the reviews, this product is horrible!! Chirping at 3:30 AM for NO REASON is the norm. I've had 3 of these, new backup batteries and all, and they all fail. Go elsewhere, I am.
Customer Rating:
Summary: Great replacement!
Comment: I purchased this to replace a broken smoke detector. This matched up perfectly with the others in service in our home and we have had no false alarms since installing.

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
