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 may 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, unsuitable venting, and attached garages can also cause carbon monoxide accumulation. In keeping with the Consumer Product Safety Commission (CPSC), a minimum of one CO alarm must 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 simple installation.
  • 120-volt AC inter-connectable (with maximum 18 compatible devices). The alarm may also 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 unexpectedly 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 lets you 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 all over power outages.

All BRK Electronics carbon monoxide alarms are listed to UL Safety Standard 2034 for residential carbon monoxide alarms. Includes 9-volt backup battery. 5-year limited warranty.–Bree Norlander
