Tools and Hardware Reviews of BRK Brands SC9120B Hardwire Combination Smoke/Carbon Monoxide Alarm with Battery Backup
Customer Review: poor design - don't buy this product
Summary: 1 Stars
The BRK combination smoke and carbon monoxide alarm requires BOTH 110VAC AND 9VDC (Energizer type battery please) for proper operation.
You can use this alarm without the 110VAC if you like, but be prepared to replace the 9 volt battery every 3 weeks. If you use the device on 110VAC only, it will emit random false "low battery level" notices - loud beeps (in the middle of the night !). BRK (the manufacturer) denied the device had any issues at all and suggested I "properly follow the instructions" (which I enjoyed reading in the Spanish version included with my superior BRK alarm system). The product description (on Amazon) says: "9-volt battery backup for peace of mind during power outages". Right.
If you are into home improvement projects, then go ahead, make this purchase. You will have a chance to make your own 110VAC cable connection - no cable is supplied. You will also be challenged to find a way to fit this cable mess into the back of the device housing - there is no space there.
If, however, you intend to purchase a smoke alarm FOR peace of mind, try another product - and another brand.

Description of BRK Brands SC9120B Hardwire Combination Smoke/Carbon Monoxide Alarm with Battery Backup
The BRK hardwire combination smoke and carbon monoxide alarm detects two hazards with one simple unit. Carbon monoxide (CO) is a colorless, odorless, deadly gas. It can be emitted by sources including gas or oil furnaces, gas clothes dryers, water heaters, fireplaces, wood stoves, charcoal grills, gas ranges, and space heaters. A clogged chimney, improper venting, and attached garages can also cause carbon monoxide accumulation. According to the Consumer Product Safety Commission (CPSC), at least one CO alarm should be installed near a home's sleeping area.The BRK SC9120 hardwire combination smoke and CO alarm with battery backup includes these features:
- Quick plug-in power connector for easy installation.
- 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.
- Ionization sensor which is more effective at detecting flaming fires which consume combustible materials rapidly and spread quickly.
- Microprocessor controlled for fewer nuisance alarms.
- Single test/silence button which both silences a non-threatening alarm or low battery warning and allows you to test the unit's functionality.
- Automatically performs internal test of functionality.
- Latching alarm indicator which automatically identifies which unit initiated the alarm.
- Separate smoke and carbon monoxide visual and audible warnings.
- Battery drawer lock and mounting bracket lock for tamper resistance.
- AC power indicator and alarm indicator light.
- Low battery warning "chirp" and missing battery tab.
- 9-volt battery backup for peace of mind during power outages.
